If someone would ask me which is the biggest learning app out there ?
I would instantly answer that it’s YouTube. You can learn anything and everything using YouTube, be it cooking, dancing, technical skills, singing, painting and writing etc.
You can even study through YouTube as well. There are a lot of entertainment and sports related videos on YouTube which get trending every now and then.
How the idea of creating such an amazing video app came up?
Not only, one can learn through YouTube but also can help others to learn new skills. It is the era of social media influencers where people have different platforms in front of them to share their creativity with millions of people through online media.
YouTube is the world’s largest video streaming website and the second largest search engine after Google.
The creators behind this wonderful innovation were Chad Hurley, Steve Chen and Jawed Karim who just not made their mission possible but also created a phenomenon that is everlasting and never gonna end anytime soon.
After college Chad Hurley worked in PayPal division where he met Steve Chen and Jawed Karim who later came together to create YouTube in 2005.
Hurley worked in PayPal till it got acquired by eBay in 2002 and after that he started working in Silicon Valley as a Consultant.
In January 2005, Steve hosted a party for his friends and Hurley was one of his guests. Both Steve and Harley recorded the party on a camcorder and digital camera but were not able to send the recording to their friends and guests because of the massive file size.
It was then they came up with an idea of creating a site which would help people to share their videos.
They wanted to do something like the concept of Flickr which was one of the new websites back then that facilitated the sharing of the photographs.
After a few days, the team came up with a memorable and consumer-friendly logo. The website was launched on February 14, 2005.
A sneak peek was offered to interested parties in May , 2005. However, potential youtubers had to wait for another six months to be able to freely enjoy the site.
YouTube employees had to work from home and even from the garages where many start-ups used to work. It had roughly 8 to 10 employees who were enthusiasts and were working without any pay.
The first video published by the YouTube was titled “me at the zoo” by one of the co-founders of YouTube who was Jawed Karim.
In no time, YouTube became a huge success.
Later in September, 2005, YouTube got its first one million hit video. The video was a NIKE ad which went viral. YouTube acquired $3.5 million funding from Sequoia Capital and made an official launch in November, 2005.
In July, 2006, the company relieved that 65,000 videos were getting uploaded on YouTube every day. It slowly became the 10th most popular website all around the world.
This much success in such a short time was unbelievable. In the later year, YouTube witnessed another huge success.
This tech video start-up got acquired by tech giant GOOGLE for a whooping $1.65 billion. The idea of two technically inclined pioneers turned out to be a revolutionary milestone in the history.
In May 2007 , YouTube launched its partner program which allowed the creators with the viral videos to get paid. Now, people started to get paid due to their hobbies, only thanks to YouTube.
In August 2007, Google decided to introduce Ads on YouTube.
In 2007, Usher introduced the world to Justin Bieber via a YouTube video which got hit and made JB one of the greatest singers in the history of music. With Gangnam Style becoming viral on YouTube also was a huge event in the YouTube history. A lot of artists made their careers through YouTube. Not only artists but also videos related to education are getting popular among the people. YouTube also helped many K-pop groups like BTS and BlackPink etc. to be popular worldwide.
Now, It has become impossible to imagine a world without having YouTube in it!!

The world’s biggest and the most popular sportswear company – NIKE . In just 50 years, one man’s dream of better shoes turned into a global corporation worth over a $100 billion.
What did NIKE had that others didn’t? How come NIKE achieved the spot where it is right now??
The year is 1962 and Phil Knight was just graduated from Stanford. Becoming a successful entrepreneur is a difficult task if you don’t have an idea which can make a bigger impact in this world.
He was a distance runner back in the university. In one of his business classes, he wrote in a paper title:
“Can Japanese sports shoes do the same to German sports shoes that Japanese cameras did to the German cameras?”
He was aware of the fact that Japanese cameras replaced German cameras and was pondering if Japanese shoes could do the same to Puma and Adidas which were domineering in America at that time.
He got so conscious of that idea of bringing Japanese shoes to U.S.A.
He could not find much exposure to Japanese shoes, so he decided to contact the Japanese company in order to import the goods in America. But he had zero experience in it.
As a determined man who created NIKE, we all know he actually did it.
In November 1962, he flew over to Japan like a tourist and just started exploring. In a beautiful city of Kobe, he laid his eyes on a shoe store that caught his eyes.
It belonged to the company called Onitsuka Tiger and the shoes they were producing at that time were of very high quality that Phil got tempted to import them to America.
He proposed to the company to let him import the shoes to America and became the distributor. Surprisingly, the company accepted the offer. He received his shipment of 12 pairs of Tiger shoes in 1963 and he started selling them at every running track he could get into.
Obviously, his strategy was not that scalable, so he approached the right person he knew at that time who was his former coach at the University of Oregon, Bill Bowerman. Bill was one of the famous coaches in America at that time. He had in fact trained multiple Olympic Athletes.
He liked the Tiger shoes so much that he wanted to partner up. Thus, in January 1964, Bill and Phil incorporated Blue Ribbon Sports, each investing $500 into it.
They spent all that money on their first order, which at $3.33 a pair, amounted to 300 pairs of shoes.
The shipment came through in April, 1964 and thanks to Bill’s connections it was sold out by July.
In their first year, BRS sold $8,000 worth of shoes and with that money Phil started hiring salesmen for his company.
In 1965, their revenue had increased to $20,000 and pretty soon they opened their very own store in Santa Monica.
But while Phil was handling the business side of the operation, the actual innovation was
coming from Bill.
He was the guy who single-handedly brought jogging to America.
In 1966, he wrote a book about it that sold over a million copies, and of course his company was among the first to start marketing the Tiger shoes for jogging.
Bowerman was all about innovation and with every new shipment from Onitsuka, he’d cut open a few shoes to see how they were made, and he’d always try to improve them, for example adding to the cushion or using more lightweight materials.
He’d constantly sent his notes to Japan requesting changes; he was effectively designing Onitsuka’s shoes for them.
It was one of Bill’s designs that catapulted BRS into the mainstream: the Cortez, as he
called it, became one of the best-selling shoes in 1968, undoubtedly thanks to the 1968 Olympics, held in Mexico.
Thanks to the Cortez, BRS sold $300,000 worth of shoes in 1969.
But they had a big problem: the Cortez was so successful that they couldn’t keep up
with the demand.
Every new shipment they received sold out faster than the one before, but Onitsuka kept sending them at the same glacial pace.
What Onitsuka were actually doing was satisfying their local demand in Japan first and then sending whatever was left to America.
Phil and Bill knew that to expand they would have to evolve beyond being just a simple
distributor. Then they realized that they held all the cards: the Cortez was Bowerman’s design
so as soon as their contract with Onitsuka expired, they were free to start making it for themselves.
Luckily for them, their contract would end in 1972, just before the Olympics in Munich.
Thus, Phil had plenty of time to prepare for his big move.
In 1971, he started working on the branding: his first employee suggested calling the brand Nike, after the Greek goddess of victory.
Then, Phil needed a logo, so he went to a nearby university, snatched the first graphic design student he could find and told her to make him a logo.
For the impressive sum of $35 he got this: the swoosh.
In hindsight, that was money well spent and with his branding now complete, Phil was ready
for the Olympics.
This time, instead of locking himself into exclusive agreements, Phil established a network of subcontractors across Japan.
With production under his control, Phil could finally spread his wings.
You can see in this graph of Nike’s sales exactly when Phil started importing shoes from his Japanese subcontractors, and yes he started before his contract had even expired in 1971.
From then on, the story of Nike became one of growth.
They became the largest sportswear company in America in 1989 on the back of brilliant marketing like the “Just Do It” campaign and by signing rookie athletes that would eventually become famous across the world!!
What Is Bitcoin?

Bitcoin is a decentralized digital currency created in January 2009. It follows the ideas set out in a white paper by the mysterious and pseudonymous Satoshi Nakamoto. The identity of the person or persons who created the technology is still a mystery. Bitcoin offers the promise of lower transaction fees than traditional online payment mechanisms do, and unlike government-issued currencies, it is operated by a decentralized authority.
Bitcoin is known as a type of cryptocurrency because it uses cryptography to keep it secure. There are no physical bitcoins, only balances kept on a public ledger that everyone has transparent access to (although each record is encrypted). All Bitcoin transactions are verified by a massive amount of computing power via a process known as “mining.” Bitcoin is not issued or backed by any banks or governments, nor is an individual bitcoin valuable as a commodity. Despite it not being legal tender in most parts of the world, Bitcoin is very popular and has triggered the launch of hundreds of other cryptocurrencies, collectively referred to as altcoins. Bitcoin is commonly abbreviated as BTC when traded.
Understanding Bitcoin
The Bitcoin system is a collection of computers (also referred to as “nodes” or “miners”) that all run Bitcoin’s code and store its blockchain. Figuratively speaking, a blockchain can be thought of as a collection of blocks. In each block is a collection of transactions. Because all of the computers running the blockchain have the same list of blocks and transactions and can transparently see these new blocks as they’re filled with new Bitcoin transactions, no one can cheat the system.
Anyone whether they run a Bitcoin “node” or not can see these transactions occurring in real time. To achieve a nefarious act, a bad actor would need to operate 51% of the computing power that makes up Bitcoin. Bitcoin has around 13,768 full nodes, as of mid-November 2021, and this number is growing, making such an attack quite unlikely.
But if an attack were to happen, Bitcoin miners the people who take part in the Bitcoin network with their computers—would likely split off to a new blockchain, making the effort the bad actor put forth to achieve the attack a waste.
Balances of Bitcoin tokens are kept using public and private “keys,” which are long strings of numbers and letters linked through the mathematical encryption algorithm that creates them. The public key (comparable to a bank account number) serves as the address published to the world and to which others may send Bitcoin.
The private key (comparable to an ATM PIN) is meant to be a guarded secret and only used to authorize Bitcoin transmissions. Bitcoin keys should not be confused with a Bitcoin wallet, which is a physical or digital device that facilitates the trading of Bitcoin and allows users to track ownership of coins. The term “wallet” is a bit misleading because Bitcoin’s decentralized nature means it is never stored “in” a wallet, but rather distributed on a blockchain.
Peer-to-Peer Technology:
Bitcoin is one of the first digital currencies to use peer-to-peer (P2P) technology to facilitate instant payments. The independent individuals and companies who own the governing computing power and participate in the Bitcoin network Bitcoin “miners” are in charge of processing the transactions on the blockchain and are motivated by rewards (the release of new Bitcoin) and transaction fees paid in Bitcoin.
These miners can be thought of as the decentralized authority enforcing the credibility of the Bitcoin network. New bitcoins are released to miners at a fixed but periodically declining rate. There are only 21 million bitcoins that can be mined in total. As of November 2021, there are over 18.875 million Bitcoin in existence and less than 2.125 million Bitcoin left to mine.
Bitcoin Mining:
Bitcoin mining is the process by which Bitcoin is released into circulation. Generally, mining requires solving computationally difficult puzzles to discover a new block, which is added to the blockchain.
Bitcoin mining adds and verifies transaction records across the network. Miners are rewarded with some Bitcoin; the reward is halved every 210,000 blocks. The block reward was 50 new bitcoins in 2009. On May 11, 2020, the third halving occurred, bringing the reward for each block discovery down to 6.25 bitcoins
Early Timeline of Bitcoin
Aug. 18, 2008
The domain name Bitcoin.org is registered. Today, at least, this domain is WhoisGuard Protected, meaning the identity of the person who registered it is not public information.
Oct. 31, 2008
A person or group using the name Satoshi Nakamoto makes an announcement to the Cryptography Mailing List at metzdowd.com: “I’ve been working on a new electronic cash system that’s fully peer-to-peer, with no trusted third party.” This now-famous white paper published on Bitcoin.org, entitled “Bitcoin: A Peer-to-Peer Electronic Cash System,” would become the Magna Carta for how Bitcoin operates today.
Jan. 3, 2009
The first Bitcoin block is mined Block 0. This is also known as the “genesis block” and contains the text: “The Times 03/Jan/2009 Chancellor on brink of second bailout for banks,” perhaps as proof that the block was mined on or after that date, and perhaps also as relevant political commentary.
Jan. 8, 2009
The first version of the Bitcoin software is announced to the Cryptography Mailing List.
Jan. 9, 2009
Block 1 is mined, and Bitcoin mining commences in earnest.
Bitcoin employment opportunities:
Those who are self-employed can get paid for a job related to Bitcoin. There are several ways to achieve this, such as creating any internet service and adding your Bitcoin wallet address to the site as a form of payment. There are also several websites and job boards that are dedicated to digital currencies:
Why Is Bitcoin Valuable?
Bitcoin’s price has risen exponentially in just over a decade, from less than $1 in 2011 to more than $68,000 as of November 2021. Its value is derived from several sources, including its relative scarcity, market demand, and marginal cost of production. Thus, even though it is intangible, Bitcoin commands a high valuation, with a total market cap of $1.11 trillion as of November 2021
Is Bitcoin a Scam?
Even though Bitcoin is virtual and can’t be touched, it is certainly real. Bitcoin has been around for more than a decade and the system has proved itself to be robust. The computer code that runs the system, moreover, is open source and can be downloaded and analyzed by anybody for bugs or evidence of nefarious intent. Of course, fraudsters may attempt to swindle people out of their Bitcoin or hack sites such as crypto exchanges, but these are flaws in human behavior or third-party applications and not in Bitcoin itself.
How Many Bitcoins Are There?
The maximum number of bitcoins that will ever be produced is 21 million, and the last bitcoin will be mined at some point around the year 2140. As of November 2021, more than 18.85 million (almost 90%) of those bitcoins have been mined.18 Moreover, researchers estimate that up to 20% of those bitcoins have been “lost” due to people forgetting their private key, dying without leaving any access instructions, or sending bitcoins to unusable addresses.
Where Can I Buy Bitcoin?
There are several online exchanges that allow you to purchase Bitcoin. In addition, Bitcoin ATMs internet-connected kiosks that can be used to buy bitcoins with credit cards or cash have been popping up around the world. Or, if you know a friend who owns some bitcoins, they may be willing to sell them to you directly without any exchange at all.

LinkedIn is a very famous employment oriented online service where various professional corporate workers and job seekers get connected with each other. It provides the best networking opportunity in this online era.
How the idea of creating this kind of site came up?
How Reid Hoffman built LinkedIn?
Reid Hoffman was born on 5th August, 1957 in California. When he was only 12, he wrote the suggestions for the gaming company and then the game developer asked him if he wanted to do something with the game, after that he started working there and received his first pay-check. After graduating from high school, Hoffman graduated from Stanford University. At Stanford, he met Peter Thiel who became his good friend from then. While being at Stanford, he pondered about influencing others at a large scale. He wanted to make a big impact in the world. Hence, he started to invest his time in making software which can be used by billions of people.
He tried to get funding from various company but got rejected each and every time. Hoffman joined Apple Computer in 1994 through the reference he got from his room-mate at Stanford. At Apple, he worked at eWorld which soon got stopped due to heavy losses.
He left Apple and join Fujitsu and overtook project management field. In July 1994, he resigned from Fujitsu and took a big step of opening his venture on his own. He named that venture socialnet.com!
SocialNet was focused mainly on online dating although you can connect with people for different purposes as well on it. It was a good venture from the beginning but it didn’t last in long run. It started to look scattered due to lack of a clear purpose. Online dating and making friends was a new idea back then which was not accepted by the people at that time.
He learnt a great lesson from this failure that the product distribution strategy is as important as the quality of the product itself.
After that he joined PayPal, where he was responsible for the external affairs department. In 2002, PayPal went public, Hoffman was a real contributor in the success of PayPal. After that he achieved the financial freedom by becoming a millionaire.
He though of taking a long break after a huge success but he got back to work only after the break of three weeks. He founded LinkedIn in December, 2002 with his teammates from PayPal and Socialnet.
He founded LinkedIn on his idea that the people would have two identities on the internet . One is their social identity which people want to show others to befriend them and the other one is the real identity which is for their achievements, educational background and works till that date.
LinkedIn is a professional networking site which connects professional people and job seekers from all over the world to help them in getting better opportunities and the better insights of real corporate world.
Initially, they invited the people they already knew about. From there, the things began to grew. In first month of operation, a total of 4500 users joined the platform. Some of them found jobs and new clients through LinkedIn which itself was fulfilling the purpose of the platform.
People started to recommend the platform and more people started to join in. By the time, LinkedIn was a year old, it already bagged about 5,00,000 users on its platform.
Meanwhile, Sequoia Capital invested in this venture. By the year 2004, the platform managed to have a million users already.
Hoffman pointed out two major problems with LinkedIn in 2006. One was its user base which was comparatively low and the other was the product itself.
He resigned from the post of CEO and appointed Dan Nye as the new CEO of LinkedIn.
He worked as CEO for two years and helped LinkedIn to grow more and more. During those two years, the site reached to 35 million users and sales jumped over 900%.
A mobile version of LinkedIn was introduced on February, 2008. In January 2011, LinkedIn filed for an Initial Public Offering.
Over the years, LinkedIn acquired many small start-ups to increase the quality of the product and make it more useful for their users.
On 13th June, 2016 , nearly 14 years after starting the company, Microsoft acquired LinkedIn for $26.2 billion.
This was the largest acquisition made by the Microsoft till date. This deal made Hoffman and his teammate billionaires!
Today, LinkedIn is the world’s largest professional networking site with over 706 million users all around the world.

A question bank can be two things: a list of all your questions created with an exam software (including all exams) and a list of all the questions in one exam.
The last definition is the one we are going to focus on. How does it work? Basically, it works like this: you create an exam and add a number of questions to it. Let’s say, 100 questions. But you don’t want your students to answer all these questions, so you set them up in a way that the exam software picks, say, 30 questions from this question bank with 100 questions, at random, every time someone takes the exam. This means every student will get a different set of 30 questions when taking the same exam. Awesome, right? ✨
Using a question bank like this helps prevent cheating, since no group of students will get the same questions, at the same order, while taking the same exam. It also lets you add more content to the exam material, since you can cover a lot more ground with a bigger set of questions (even though the students are not getting all of them) than with just a few questions.

Test Banks gives you a unique opportunity to test your knowledge as you get access to all 500+ Govt Exam Mock Tests available on the Career Launcher platform. These Tests are prepared by the Finest Faculty team under the supervision of Career Launcher Mentors. Every Mock Test is followed by a Detailed analysis which helps you to find your areas of improvement.
I understand that instructors vary in their testing preferences. Some prefer to test learning by the student”s ability to apply the material to a case. Often this is done through assigned papers. Others like objective formats. Many use a combination of objective tests/quizzes and papers. Generally I regard test-making/taking as another teaching/learning opportunity.
This test bank attempts to provide a variety questions in different objective formats as students vary (recall, recognition, compare/contrast, critical thinking essay) in how they can best demonstrate that they have learned the material. Some of the same content has been asked in different objective formats, therefore the instructor must be careful in selecting the questions they use to create a quiz or exam. Instructor must also decide how many points to assign to the questions they select. I recognize that developing a test bank is not an exact science. Sometimes students have a take on a question that was not anticipated by the test-maker.
A Test bank is a ready-made electronic testing resource that can be customized by lecturers for their teaching.
Written by an OUP author, it is tailored to the contents of an individual textbook. Feedback is often provided on answers given by students, containing page references to the book.
Questions can be any of the following types:
Test banks are available in a number of software formats to cater for a wide range of users, and are password-protected to ensure that only lecturers gain access.
Online test banks are used worldwide. They are prepackaged online resources meant for lecturers creating tests and sometimes provided through educational institutions. Online test banks are attractive because they are often created by the same publisher that produced the corresponding textbook for that course and thus centered around the main topics of that individual textbook. The test banks offer a diverse selection of questions and can include feedback on a specific answer given directly by students, often accompanied with exact page references to the textbook.
The initial use for test banks was as a time-saving resource for instructors crafting tests for their courses. They evolved into tools for students preparing for an upcoming exam, offering a curated selection of questions directly related to the topic. These days, online test banks are no longer limited to questions chosen by a textbook publisher; they now include collections of actual exams uploaded to the internet.
One such example was Fratfolder.com, which started in 2007. At that point, it was somewhat common practice amongst sorority and fraternity houses in university settings across North America to share exams as a study tool. Alex Baldwin thought making the exam content more easily accessible to students beyond the fraternity and sorority scene was a type of “public service, leveling the academic playing field by giving non-Greeks access to the same test banks while providing students insight into how individual professors structure their exams.”
Fratfolder is no longer accessible online, but many other sites are, begging the question: how does an instructor know when/if a student has used an online test bank? They may manifest in student work in a variety of ways:
With such a focused study tool, students may feel that the time they spend preparing for the exam is not only efficient, but convenient, with everything they need in one place. Online test bank material is often marketed as “study material” and an “additional resource” for students with busy schedules. What is also true is that sometimes instructors themselves will choose to hand out previous exams as a study resource for their students. One professor from Wichita State University stated: “If this is something that I want my students to learn, why won’t I give them as much practice information as I can?”
Unfortunately, an online collection of previous tests blurs the line between copyright law and academic integrity. Exams or test questions that are uploaded without an instructor’s consentmeans that they did not willingly share their course’s content, nor their original exam material. Most educators are up in arms about the increased use of online test banks because it means their tests—truly, their intellectual property—are available online without their permission.
Furthermore, if a student or set of students simply memorizes answers to a previous test, are they actually exhibiting knowledge, applying learned concepts to a new setting? Professors may not see that a student or an entire class needs additional support or coverage on a challenging topic because the exams do not accurately reflect their learning. And if exams are simply passed from one student to the next, then the deep value of attending the course, absorbing the information, engaging in class discussions, and asking questions, are all lost.
Luckily, there are several ways to reduce the negative impact of online test banks on student learning.
In the end, talking to students openly about online test banks may be the perfect deterrent for the misuse of this resource. And while most situations involving study materials are likely honest endeavors, knowing the evolution of online test banks and how they are being used will help everyone to ground themselves in the importance of academics and assessment with integrity.
Money, if someone would ask what exactly money is for me then I would tell him without hesitation that it is the thing that can either make me or break me.
Pretty daring, right! When you know that without money, you can’t even survive by yourself then why not better manage it carefully. From office workers to comedians, everyone needs to manage their money.
Investing your money as early as possible is what we need in this era. When your money is sitting idle in your banks, there would be person who’ll be multiplying his assets through investment in other corner of the world.
First advice: Don’t take loans hastily
You get bound with liabilities once you take loans. Buying a house is definitely gonna help you in making assets, but buying it with the money from your loan will increase the liabilities. Taking education loan is still fine as the ROI ( Return On Investment ) in this case would not only include the money but also your overall personality . But always ensure to take the education loan under your own name. Avoid taking personal loans or loans to buy bikes or cars etc. At your 20s, it’s necessary for you to reduce and eliminate the loans as much as possible.
Second advice: Insurance
For the planning of unforeseen or any unexpected situation that might occur in your future, Insurance for that time becomes inevitable. There are two types of insurance which are highly recommended and attainable:
First is Life Insurance and
Second is Health Insurance.
In Life Insurance, choose term plan. As a working professional, to get a good idea of cover, 20 to 25 times of your current salary would surely make a good cover. If you have salary of 6 lakhs per annum then a financial cover of 1.5 crores would be a better choice which comes under a term insurance plan. If you are in twenties then you could get this cover in minimum price which is a huge benefit in itself.
Health Insurance should be taken for everyone dear to you. If you work in a company then it is most likely they would have a corporate health insurance on their own which would cover you and your family.
When should you start investing?
In your twenties, when you don’t have to pay large amount of taxes due to low income, you have the potential to invest as much as possible at that rate.
What is the right investment ratio?
Investing at least 20 percent of your income is the best choice. If you are investing 50,000 per month then investing at least 10,000 rupees is an ideal choice. In 20s, no one expects you to be rich from the beginning of your working life. When no one expects from you then you have the less pressure on you , so why don’t you use that to be focused on doubling your assets as much as possible through investing. Having luxurious food, living in lavish places and hanging out with your friends is not necessary but having financial freedom as soon as possible is the most important thing in the 20s. If you invest 1 rupee from your twenties and if you invest the same 1 rupee from your 30s then it will make a huge difference.
In 10 years, the same rupee would lose half of its value meaning the value of 1 rupee now would be equal to 50 paise in the next ten years and that is how inflation works.
Inflation is the biggest reason for you to start investing as early as possible.
To get a satisfying return through your investment, where should you start to invest exactly?
Firstly, avoid investing in FDs (Fixed Deposits). FD is the worst investment you can make if you are in your in 20s. As you are free to take risks in your 20s then let your money to grow as much as possible than to protect it under the name of FD.
Invest and hold in stocks and equities..
Invest in the stocks of the companies which are doing great in the market but if you don’t have the knowledge of the stocks that much then invest in mutual funds. You can invest in direct stocks, portfolio stocks and in cryptocurrency (though it’s a bit risky)..
Don’t wait for your 40s to invest. Start investing your money in 20s as soon as you begin to earn!!

The end…
Way back in 1992, an immigrant from Ukraine came to the U.S. in search of some opportunity. This young teenager was accompanied by his mother and they’d barely had any money for their daily expenses. Due to the limited cash on hand, he used to save his old Soviet notebooks for schools and queued up with his mom for food stamps under government subsidy.
At the same time there was another guy who had lost a small fortune in the.com bubble and wasn’t close to finding something big. Now the friends have come together to disrupt the communication sector by merging a mobile messaging app that today has over 1.2 billion monthly active users with over 30 billion messages sent every day the friends. This journey is about Jan Koum and Brian Acton who founded the company together which is none other than the most popular mobile app currently in the world WhatsApp…
Jan is no stranger to failure and as a founder who had to go through his fair share of reductions by top tech companies including the one that eventually bought their servers only to become the most valuable messaging platform on the planet.
Jan was born in the rural areas of Ukraine this was during the Soviet era so being a Jewish and living in a rural area was definitely not easy. He lived in a house that did not even have electricity connection. Being in a country that mostly had a temperature below zero degrees, they didn’t even have hot water.
His parents also denied the usage of course because they were often tapped by the government. To worsen things more being financially unwell , they also had to go through a regularity of hardships as well. Hence, in an attempt to put an end to all the sufferings, Jan along with his mother and grandmothers decided to move to Mountain View, California in 1992. In the U.S. , they were helped by a social support program to get a small two-bedroom apartment.
During this time, Jan started learning computer network by reading manuals that he used to purchase from a used bookstore at the age of 16. He had also begun working as a cleaner at a grocery store while his mother worked as a babysitter. Just once, things began to look normal, another tragedy hit his life when his mother was diagnosed with cancer but he became more stronger and his adversities were only making him more resilient. In the next two years, he had fully trained himself all about computer networking and was all set to take the next step. This is when he gains a sudden interest in programming and got himself enrolled at San Jose State University along with that he also began working with Ernst & Young as a security tester.
After working there for roughly six Months, Jan got the biggest opportunity of his life where he got selected to work at Yahoo as an infrastructure engineer. Now this was when he was still studying at San Jose State University.
Yahoo Back then was just another start-up and was beginning to grow and since Jan loved what he was doing he dropped out of his college and moved ahead with Yahoo. However, the happiness was short-lived and his mother couldn’t out beat cancer for long and passed away in the year 2000. He was suddenly left all alone and that is when his friend from Ernst & young and Yahoo, Brian Acton helped him fight the loneliness by inviting Jan to his house for playing soccer. Together they went on to work with Yahoo for more than nine years. they got to intake numerous amounts of priceless knowledge and experience. Later in January 2009,
Jan bought an iPhone and realized that the seven-month-old App Store was in the process of launching a whole new range of apps. This gave him a brilliant idea although the idea itself was at very nascent stages. They were very clear about three rules:
Additionally it would also maintain to deliver the product without any gimmicks or signs with endless amount of readability and rich experience. Having said that, Jan quickly got the name WhatsApp incorporated on his birthday that is on 24th of February 2009 in California. Now, as the world progressed, they figured that WhatsApp kept crashing or getting stuck at a particular point, this went on for a long time. It built up a great amount of frustration. Jan at one point even lost hope and felt like giving up and started looking for a new job but Brian helped him to motivate and got his act together and asked him to invest a few more months. And finally a few months down the line, help came from Apple.
They launched their push notifications which used to pin their users whenever they were using the app. By August 2009, WhatsApp had no significant growth. This time Jan persuaded Brian Acton to join the in.
Later, on October 2009, Brian contacted several old Yahoo buddies and got together a 250,000 dollars in seed funding. This made Brian to earn the title of co-founder and since then there was no stopping to this Tech phenomena.
By the early 2014, WhatsApp has witnessed humongous growth In its user base with millions of people across the globe using its messaging service. WhatsApp had never publicized or promoted itself anywhere and at organically growing numbers. By this time, it only had 55 employees over serving millions of people each day. Later the very next month in February 2014, Facebook declared that they were acquiring WhatsApp. It was the deal which is known to be one of the biggest acquisitions in the tech history.
Facebook acquired WhatsApp at a whooping 19 billion dollars and also offered a board member position to Jan in Facebook. Jan signed the Facebook take over contract at an unused building in Silicon Valley where he and his mother once queued for food stands in the city of Mountain View where WhatsApp was located!
Well the story of WhatsApp is yet another live example of innovation in true terms for everyone out there waiting for motivation. The journey of Jan Koum and Brian Acton is a lesson for every entrepreneur that capital jumping and marketing will not reap benefits, it is ultimately the product and service that automatically drives customers’ attraction without any need for paid publicity.
Well with billions of users addicted to WhatsApp style, it is undoubtedly a tech marvel of this era!!

“They frame it as if the whole reason for making Facebook and building something was because I wanted to get girls or wanted to get into some kind of social institution they just can’t wrap their head around the idea that someone might build something because they like building things” – Mark Zuckerberg.
Mark Zuckerberg, the programming prodigy who turned to town for making cool things into social network dynasty the website he started in his dorm room when he was 19 years old is one of the most influential in the world with profiles for over a quarter of the world’s population. Zuckerberg became a self-made billionaire before his 24th birthday!! How is that possible that’s what we’re gonna find out…
Mark Zuckerberg was born on May 14th, 1984 in upper-middle class parents in the outskirts of New York. His father told him to go basic in the early teens and Mark really took to it. He created a program that allowed the computer at his dad’s dental office to communicate with the family computer in Colditz arcnet.
The program was an early form of messenger while in school he excelled a number of subjects from computer science to languages and literature, he transferred to Exeter prep school where he met his good friend Adam D’Angelo.
They created music software called synapse that learned what music people liked and made suggestions based on it as writer Jose Antonio Vargas said
“some kids played computer games…. Mark
created them”. It was clear he had an entrepreneur’s mindset from an early age. Synapse was treated as a high school project but drew the attention of big software companies including Microsoft who apparently offered Zuckerberg a rumored 1 million dollars for it as well as a job before college.
Despite the job offer Zuckerberg chose to attend Harvard doing computer science and philosophy his first year of college plus without any significant creations, probably love partying. It was in his sophomore year that he began to show signs of things to come.
He created a site called Coursematch at the beginning of his second year which had led his classmates to log in and see what courses their friends. It quickly became popular which prompted Zuckerberg to try a new idea he’d recently had that he’d go on to call face masters. Facemash was created October 2003 with the intention of finding the most attractive person on campus.
Slowly a ranking was formed that created the entire thing during a tipsy eight-hour coding session that ended at 4 a.m. Despite the drunken programming, Facemash was an instant hit, been used by 450 students in one day before the Harvard admin team shut it down to new plates of sexism things.
Zuckerberg was put under probation over the incident “I was thread with exclusion” although apparently didn’t faze him too much at the time as it’s written in David Carr Patras book the Facebook Effect “ it’s not the mark necessarily set set to break the rules… he just doesn’t pay much attention to them”.
Over the next few months, undeterred by his warning from Harvard’s, Mark worked more on computer programs simply because he enjoyed it, he created a web program that brought art images from his art in the time of Augustus class and encouraged his classmates to add comments beside them to create study aids. He then used these notes to cram for an exam far more quickly. He also created a program called six degrees of Harry Lewis, a program that created links between people and his favourite computer science professor. He also began to work on other people’s produce , setting up a website for the association of Harvard black women and significantly helping three Harvard seniors finish coding on their web site idea the Harvard connection.
Zuckerberg was sold for the project in November, 2003 after the founders heard about Facemash through the Harvard magazine. They asked him to finish programming their social network site Harvard connection since he didn’t have much coding experience themselves Zuckerberg agreed to do it soon lost interest in favour of his own site, the Facebook. He stalled the
Harvard connection team by coding his new site and may have borrowed some ideas which led to a lawsuit and even a movie down the line although the initial idea of sourcing process may not have been entirely on the up the execution and launch of
Facebook was close to flawless. Zuckerberg bought the domain the facebook.com on January 11th for $30 and officially launched the site. On February 4th , by emailing a few of his friends to check out just four days after it launched, 450 Harvard undergrads signed up and 300 joined the following day. As previously mentioned, he had a knack for building social websites that people wanted to use. The idea of
Facebook was to move the physical books the university issued with a picture of all the students called face books online and students to update them with more recent pictures. It also allowed students to see what other students were talking about, what their interests were and also their relationship status. Another two weeks later , Facebook had over 6,000 users which formed over three-quarters of the undergraduates as well as some alumni. Not only did thousands of students sign up but they also readily spent hours on it each day which made it unique to every other website. Zach put a team of his roommates and friends together to handle various aspects of the project as he didn’t yet consider a business.
Eduardo Saverin handled business ,Dustin Moskovitz was a programmer, Andrew McCollum was a graphic artist and Chris shoes as a spokesman all joined the team. With the team around him that complemented his strengths and weaknesses, Zuckerberg tried to span
Facebook into other colleges starting with the Yale, Stanford and Columbia. Facebook sweat the competition and the number of people signed up kept growing.
It took them a few weeks for 80% of each of the campuses to sign up for Facebook. The team decided to rent an apartment in Palo Alto for the summer as it was where all the big start-ups seemed to come from.
After many 16-hour days, in all-nighters Facebook reached a hundred thousand users in June 2004. Just four months after its launch, a venture capital firm offered ten million dollars to buy Facebook.
He apparently didn’t even consider the offer and often said to continue drawing it for themselves. For Zach, it was never really about the money but always about really a really cool product. Over the summer, the team continued to expand Facebook’s functionality and user base. They also met Sean Parker, a Silicon Valley veteran, who became their president and introduced him to investors including
Peter Thiel who put 500k into the venture for around ten percent of the Business. All in all, a pretty solid Investment. It took Mark and his friends all of two minutes to decide to postpone their Harvard return as the social network was all about timing and they didn’t want to screw this up.
“Well that’s unclear… I am 21 but I finished my sophomore year and came out to Palo Alto fully expecting that I’d actually go back to Harvard in the fall but didn’t quite make it after Peter put his money in but started building a company instead and I got a little side-tracked but fortunately Harvard lets you take indefinite periods of time off so you know if the sever falls through… I’m back at Harvard”, he said.
They’re dropouts. The team focused on expansion, they hit many road bumps and continued to work extremely hard but it paid off for them as they reached a million users in early 2005. They continued to add more features such as the ability to share photos and post on people’s walls and their valuation kept climbing.
If we fast forward seven years, Facebookwent public in the largest tech IPO to this date and become the company over a hundred billion dollars and made all the founders billionaires while still in their early to mid-20s. While there’s no doubt Mark’s a genius. There are so many things that we can learn about him and his story so far.
Facebook was an example of a great idea at the right time with fantastic execution. They made many mistakes along the way but it all paid off in the end. One thing we have to remember is that the multi-billion dollar company that we all use today was started by a handful of forward-thinking teams in a college dorm room. With that in mind, encourage yourself to keep hustling towards your own goals!!
Gandhi first proposed a flag to the Indian National Congress in 1921. The Indian flag was designed by Pingali Venkayya.In the flag the deep saffron colour is for courage and sacrifice white colour is for honesty, peace, and purity dark green colour is for faith and chivalry and the chakra in the middle is for vigilance, perseverance, and justice.This flag was accepted in 1947.Bhikaji Rustom Cama, the fiery lady who unfurled the first version of the Indian national flag a tricolour of green, saffron, and red stripes at the International Socialist Congress held at Stuttgart

The Indian flag was designed as
A horizontal triband of India saffron, white, and India green; charged with a navy blue wheel with 24 spokes in the centre.The flag was proposed by Nehru at the Constituent Assembly on 22 July 1947 as a horizontal tricolour of deep saffron, white and dark green in equal proportions, with the Ashoka wheel in blue in the centre of the white band. From 26 January 2002, allowing private citizens to hoist the flag on any day of the year, subject to their safeguarding the dignity, honour and respect of the flag.

* Deforestation is one of the reason for global warming.
* The smoke from vehicles.

EFFECTS OF GLOBAL WARMING:-
* Global warming cause increase in temperature that raises sea level can cause flood.
* Global warming raises temperature in the atmosphere.
* Melting of glaciers are one of the most threat for the earth
* If global warming cause increase in temperature then there is threat for availablity of water.
* It also cause some diseases like allergies,chest pain etc.

CONTROLLING MEASURES OF GLOBAL WARMING:-
* By decreasing deforestation and encouraging affrostration
* By making awareness programmes.

BLACK HOLE!!
Is black hole a pitch dark pit??
Want to know what a black hole is? But just give up everytime watching a typical definition soaked with physics on wikipedia about how even light can’t pass through it….Is black hole a big hole? But if it is a hole, how to get to know about its color? First of all I want to make sure it clear that a black hole is anything but empty space. Infact it is a place where huge matter is packed into a very small area…..what does that mean now??😦
Got confused🥴 okay then come with me to the wonderland of Alice where we see a magic✨ ‘gravity machine’ – a device with which we could control Earth’s gravity, by turning a dial. Initially it is at 1g, gravity that we are used to experience since childhood. Okay just turn the dial to 0g and you will see all your friends floating in the air even with the slightest motion. The tea☕ that you spilled on your beloved to make an old romantic movie scene, formed spherical globe in the air. Yes, balls of tea everywhere💦. But just to make a scene memorable I changed the dial to 1g and taadaa here you get the rain of tea🌧️ as earth got its gravity back….Now I again changed the dial to 3g to 4g…. everything becomes immoblised. Even if you want to have a normal walk under the sky with your crush, it requires enormous efforts. As kindness, I am removing you and your friend from the domain of gravity machine before I dial a higher gravity number. Okay, now I dialed 1000s, trees become squashed but beam of light is straight. Now at 1 lakh gs, rocks are crushed by their own weight but beam of light is still straight. When a gravity approaches a billion gs, something strange happens, the beam of light which was going straight to the sky starts bending. Now imagine a dial greater than billion gs, nothing, not even a beam of light can get out, it would bend back to the starting place. Such a place is called black hole. That is why it is called black: no light can escape from it. A place whose density and gravity is very high. But the question is from where it’s formed??……..(To be continued)
Cadbury, one of the biggest chocolate brands in the world with operations in more than 60 countries and billions of dollars in revenues. It is not only a brand of mouth-watering chocolates liked by Consumers of all ages, but also one with a 200 year old history filled with wonderful achievements and depressing failures.
Let’s dive into the origins and rise of Cadbury and see how they got to where they are today coming from a wealthy family of Quaker Christians in Britain, John Cadbury, just like any other member of his community was not allowed to attend Universities and his non-violent beliefs and values Kept him out from Joining the military. So, starting a business was the only option for him to make a living. That is why, in 1824 he Opened A Grocery Store In Bull Street, located in the city of Birmingham, UK.
As Alcohol was considered bad For Society by quaker community Tea, Coffee, Cocoa and drinking Chocolate were seen as healthy alternatives by them including John himself. That’s why among other things he sold high quality Cocoa and drinking Chocolate in his store, which he used to prepare using a pestle And mortar.
Due to high demand in 1831 John moved to a four-story warehouse nearby and started producing Cocoa and drinking chocolate on a commercial-scale.
Thus, the Cadbury manufacturing business was born.
Because of the high cost of production these were sold mainly to the wealthy people. By, 1842 he was selling around 11 varieties of Cocoa and 16 varieties of chocolate.
In 1847, his brother Benjamin Cadbury became a partner in the business and the company came to be known As Cadbury Brothers. The same year they rented larger factory in Birmingham which had a private canal that connected to all the major ports in Britain.
In 1854, the Cadbury Brothers of Birmingham received an exclusive royal warrant as manufacturers of chocolate and Cocoa to Queen Victoria this was a great luck for them as businesses which used to have these warrants had a better and sophisticated image among general buyers. However, just six years later in 1860, they had dissolve their partnership due to John’s wife’s Death and his declining mental and physical health. In 1861, John handed over the complete control of the business to his sons Richard and George Cadbury who were 25 and 21 at that time. During this time the market was not doing well and most chocolate manufacturers in Britain were going out of business of which Cadbury was not an exception.
Richard and George invested 4000 pounds each from their inherited money and started to work long hours to keep the business alive. But their turning point came in 1966 when they decided to buy a new type of Cocoa press developed in the Netherlands which removed much of the unpalatable Cocoa butter from the Cocoa beans. Up until this point almost all Cocoa makers including Cadbury had a high level Of Cocoa butter in it, to which they had to add starches to mask its taste and texture. But with this press, that would not be necessary anymore. However, buying this machine was a massive risk for Cadbury as it was expensive, they had very little money to invest, and no one knew if there would be enough demand for the products that came out of it.
But they decided to go for it and were the first British manufacturers to do so. Thus they introduced the Cadbury Cocoa Essence as the UK’s first unadulterated, pure Cocoa. With its high quality and extensive marketing it became extremely popular leading to dramatic sales numbers and changed the future of British Cocoa industry.
In 1893, George Cadbury bought 120 acres of land surrounding the factory at his own expense to create a model village so that many more of their workforce could be given a healthy, pollution free And greener environment where they could thrive. By 1900, this was expanded to 330 acres with 313 cottages and houses along with other facilities like playgrounds, swimming pools and medical centres. Many more similar properties were built in.
The years leading up to the First World War, with smaller developments taking place later on in the 20th century. In 1897, Cadbury introduced their First Milk Chocolate bar. Although they were making milk chocolate drinks from 1849. This was a new recipe that they copied from contemporary Swiss Chocolate manufacturers.
But in terms of texture Swiss Chocolates were far superior as they added condensed milk instead of milk powder. Because of this, Swiss Companies dominated the British Market which Cadbury started to challenge. In 1904, Cadbury launched their Dairy milk bar. Developed by George Cadbury Junior, it was a production of exceptional quality with a higher proportion of milk than any previous chocolate in the market. On the suggestion of a customer, it was named Dairy Milk. With a distinctive and attractive purple wrapper, gradually it became, Cadbury’s best-selling product by 1914.
Due to the shortage of supply, the British Government banned manufacturers from using fresh milk. So, dried skimmed milk was used instead. Due to these issues with essential supplies, the Dairy Milk and many other Cadbury products came Off the shelves during The War. But once the war ended, the company worked hard to restore their business did a lot of promotions, kept competitors away with a direct distribution chain and continued launching new products like Milk Tray Bars, Fudge, Toffee Buttons and Picnic. In a few years they were back to the game like before.
In 1969 ,they merged with Swiss Drinks company Schweppes and demerged again in 2008.
Then in 2010, Kraft Foods bought the brand for an astounding $19 billion but they themselves split into two companies one of which was named Mondelez International which owns the Cadbury brand till date.
In 2019, Mondelez ranked 116 in the Fortune 500 list of largest corporations by total revenue.
As of today, Cadbury is the second largest confectionery brand in the world with products ranging from chocolates, ice cream and beverages to biscuits, desserts, spread and much more.
With operations in more than 60 countries including the UK, USA, Canada, South Africa, New Zealand, Australia and India, it continues to be one of the most favoured name in the segment of chocolates, confectionaries and most probably would continue to be so for a long time!!
The harsh winter weather will cause flakiness and dryness of the skin, creating it look dull. Therefore, it becomes extraordinarily necessary to produce the skin with the correct nourishment, and keep it hydrous and protected. When weather condition arrives, humidness levels drop drastically, says a dermatologist.
During winters we have a tendency to all notice the skin going dry, rough and flaky. it’s important to require correct skin care throughout winters therefore on build your skin healthy and glowing.

Moisturizers act as a barrier, holding wetness in and hydrating the skin’s outer layers. If you’ve got oily skin, water-based, non-comedogenic moisturizers are the simplest choice. Dry skin desires a heavier, oil-based moisturizer to rehydrate. Moisturize your skin frequently and don’t forget to wear a lip balm.

Hot water evaporates fast, stripping your skin of its essential moisture and damaging its natural protective barrier. Moisturize immediately after showering with a body lotion.

Harsh winter weather creates a challenge for the skin as humidity is low each inside and out. Employ a humidifier helps replenish the top layer of the epidermis by preventing the air from becoming too dry.
Humidifiers are generally safe for all skin types to use. However, it is important that you take the time to clean and maintain your appliance.

During winters opt for creamy or balm based cleansers and products. Look for mild skin cleansers labeled as “fragrance-free.” And should also contain mild ingredients. Using a transparent body bar made with glycerin will clean and moisturize the skin without causing irritation. Always wash gently without scrubbing to avoid skin irritation.

Never ever skip a sunscreen in your skincare routine. The most necessary factor you’ll do for your skin is to wear sun screen each single day, even once it’s winter. Sun exposure can result in pigmentation issues, wrinkles and skin cancer. Sunscreen always protects your skin from harmful UV rays.

Look for ingredients such as rosehip oil, soybean oil, and jojoba oil and vitamin E, which all possess highly hydrating and moisturizing properties.

These include ingredients such as mineral oils and aggressive acid peels, using scrubs or acid peels on dry may create patches and peel off the skin causing skin damage. It damages the cells and reduce skin –barrier function resulting in trans epidermal water loss.

Hyaluronic acid is an incredible acid needed to add in your skincare routine. Hyaluronic acid serum acts as a humectant a substance helps the skin hold on to water. It helps to hydrate the skin and lockup moisture content into the skin.

Always try to stay hydrated consuming adequate amount of water during winter season. If your skin is dehydrated, it becomes flaky, dull and dry. Hydrated skin is smooth and radiant so keep up the water consumption so that winters don’t let go your skin dehydrated.

The skin here is thinner and has little-to-no oil glands to shield itself. Use serums, under eye creams and oils around the eyes that soothe and protect the skin. On the lips, use balms to supply a barrier against the weather and to lock in the moisture.

* longer life span
Positive thinking isn’t magic and it won’t make all of your problems disappear. What it will do is make problems seem more manageable and help you approach hardships in a more positive and productive way.
How to think positive thoughts:
Positive thinking can be achieved through a few different techniques that have been proven effective, such as positive self-talk and positive imagery.
Here are some tips that to get you started that can help you train your brain how to think positively.
Focus on the good things:
Challenging situations and obstacles are a part of life. When you’re faced with one, focus on the good things no matter how small or seemingly insignificant they seem. If you look for it, you can always find the proverbial silver lining in every cloud — even if it’s not immediately obvious. For example, if someone cancels plans, focus on how it frees up time for you to catch up on a TV show or other activity you enjoy.
Practice gratitude:
Practicing gratitude has been shown to reduce stress, improve self-esteem, and foster resilience even in very difficult times. Think of people, moments, or things that bring you some kind of comfort or happiness and try to express your gratitude at least once a day. This can be thanking a co-worker for helping with a project, a loved one for washing the dishes, or your dog for the unconditional love they give you.
Keep a gratitude journal:
Studies Trusted Source have found that writing down the things you’re grateful for can improve your optimism and sense of well-being. You can do this by writing in a gratitude journal every day, or jotting down a list of things you’re grateful for on days you’re having a hard time.
Open yourself up to humor:
Studies have found that laughter lowers stress, anxiety, and depression. It also improves coping skills, mood, and self-esteem.
Be open to humor in all situations, especially the difficult ones, and give yourself permission to laugh. It instantly lightens the mood and makes things seem a little less difficult. Even if you’re not feeling it; pretending or forcing yourself to laugh can improve your mood and lower stress.
Spend time with positive people:
Negativity and positivity have been shown to be contagious. Consider the people with whom you’re spending time. Have you noticed how someone in a bad mood can bring down almost everyone in a room? A positive person has the opposite effect on others.
Being around positive people has been shown to improve self-esteem and increase your chances of reaching goals. Surround yourself with people who will lift you up and help you see the bright side.
Practice positive self-talk:
We tend to be the hardest on ourselves and be our own worst critic. Over time, this can cause you to form a negative opinion of yourself that can be hard to shake. To stop this, you’ll need to be mindful of the voice in your head and respond with positive messages, also known as positive self-talk.
Research shows that even a small shift in the way you talk to yourself can influence your ability to regulate your feelings, thoughts, and behavior under stress.
Here’s an example of positive self-talk: Instead of thinking “I really messed that up,” try “I’ll try it again a different way.”
Identify your areas of negativity:
Take a good look at the different areas of your life and identify the ones in which you tend to be the most negative. Not sure? Ask a trusted friend or colleague. Chances are, they’ll be able to offer some insight. A co-worker might notice that you tend to be negative at work. Your spouse may notice that you get especially negative while driving. Tackle one area at a time.
Start every day on a positive note:
Create a ritual in which you start off each day with something uplifting and positive. Here are a few ideas:
* Tell yourself that it’s going to be a great day or any other positive affirmation.
* Listen to a happy and positive song or playlist.
* Share some positivity by giving a compliment or doing something nice for someone.
How to think positive when everything is going wrong:
Trying to be positive when you’re grieving or experiencing other serious distress can seem impossible. During these times, it’s important to take the pressure off of yourself to find the silver lining. Instead, channel that energy into getting support from others.
Positive thinking isn’t about burying every negative thought or emotion you have or avoiding difficult feelings. The lowest points in our lives are often the ones that motivate us to move on and make positive changes.
When going through such a time, try to see yourself as if you were a good friend in need of comfort and sound advice. What would you say to her? You’d likely acknowledge her feelings and remind her she has every right to feel sad or angry in her situation, and then offer support with a gentle reminder that things will get better.
Side effects of negative thinking:
Negative thinking and the many feelings that can accompany it, such as pessimism, stress, and anger, can cause a number of physical symptoms and increase your risk of diseases and a shortened lifespan.
Stress and other negative emotions trigger several processes in our bodies, including stress hormone release, metabolism, and immune function. Long periods of stress increase inflammation in your body, which has also been implicated in a number or serious diseases.
Some of the symptoms of stress include:
* headache
* body aches
* nausea
* fatigue
* difficulty sleeping
Cynicism, stress, anger, and hostility have been linked to a higher risk of:
* heart disease
* heart attack
* stroke
* dementia
When to seek medical help:
If you’re feeling consumed by negative thoughts and are having trouble controlling your emotions, see a doctor. You may benefit from medical help, such as positive psychology or therapy. Persistent negative thoughts can be caused by an underlying psychiatric condition that requires treatment.
Takeaway:
You won’t be able to undo years of pessimism and negative thoughts overnight, but with some practice, you can learn how to approach things with a more positive outlook.
John S. Pemberton first produced a drink in 1866 and named it COCA-COLA.
It is a really astonishing fact that the beverage with 1.9 million daily servings was initially made as an alternative to morphine, a pain reliever.
Pemberton was working as a colonel in the confederate during the American Civil War as well as a pharmacist. He sustained a saber injury from the war in April 1865 and was prescribed morphine to relieve his pain.
He realised that gradually we was becoming addictive to morphine and decided to prepare an alternative that would not contain morphine in it. He then experimented with a lot of different pain relievers.
After a lot of trials, he finally came up with an alcoholic wine that he called Pemberton’s French Wine Coca. The drink was mixed up with cocaine extracted from coca leaves and caffeine from kola nut. Pemberton registered this French Wine in 1885. In 1886, Atlanta and Fulton County prohibited that wine,
This led to development of a non-alcoholic version of the wine.
Pemberton relied upon the Atlanta drugstore owner Wills E. Venable to help him perfect the product.
While trying to make the beverage, he accidently mixed the base syrup with carbonated water which eventually gave birth to the drink Coca- Cola.
Frank Mason Robinson, Pemberton’s bookkeeper and partner came up with the name Coca-Cola which is the hybrid of the coca in Cocaine and cola ad in kola nut spelled as ‘cola nut’ at that time. Robinson also hand wrote, using the standard writing script for business correspondence in the U.S. at that time; Spencerian script on the bottles and ads, which are still in use until today.
The Coca-Cola was first sold at Jacob’s Pharmacy in Atlanta, Georgia on the 8th of May, 1886 at 5 cents per glass at soda fountains, which were popular at that time in U.S. due to the belief that the carbonated water was good for the health.
Pemberton claimed Coca-Cola as a brain tonic which could cure many diseases such as morphine addictions, headaches, nerve disorders and impotence. It sold 25 US gallons the first year. By 1888, three versions of Coca- Cola were produced and sold by three separate businesses. Years later Asa Griggs Candler, an Atlanta Pharmacist and businessman stated in the testimony that he had acquired stakes for $2,300 in Pemberton’s company as early as 1887. Candler sold products called ‘yum yum’ and ‘koke’ which he prepared with the same formula while Charley Pemberton, the son of John Pemberton, kept selling cruder syrup under the name of Coca-Cola. After the death of Pemberton, Candler bought the name ‘ Coca-Cola’ for $300.
By 1888, Candler had the full control over the ‘Coca-Cola’ company. In 1889, Benjamin Thomas and Joseph Whitehead, two entrepreneurs from Chattanooga, Tennessee suggested bottling and offered to be in charge of the procedure. They were so compelling that Candler agreed to a contract of only one dollar granting
them exclusive rights to bottle and sell the Coca-Cola.
Candler never collected his one dollar.
The first bottling of Coca-Cola was done in Biedenharn Candy Company in Vicksburg, Mississippi
in 1894 with John Biedenharn as proprietor.
In 1899, the first Coca-Cola bottling company was set up in Chattanooga, Tennessee.
The contract came with many issues for the Coca-Cola Company.
It stated that each bottle was to be sold at 5 cents without stating a specific period.
As a result, a bottle of Coca-Cola was sold at 5 cents from 1886 to 1959.
The first outdoor wall advertisement of Coca-Cola was painted in Cartersville, Georgia in 1894.
Coca-Cola from 20th Century In 1910, the papers of the old Coca-Cola Company
were burned during a move to New Corporation offices and surprisingly in 1914, Margaret
Dozier, came out to profess that her signature on the Coca-Cola company bill of sale was
forged.
Analysis of certain similar transfer documents showed that John Pemberton’s signature was
forged and some accounts show that Charley Pemberton did it.
However, on September 12, 1919, a group of investors purchased the company for $25 million
and proceeded to release five hundred thousand shares to the public with each share costing
about $40.
In the same year, the company merged with Johnston Coca-Cola Bottling Group Inc. and
in 1986, the Coca-Cola company merged with two of its bottling companies, owned by HTL
corporation and BCI Holding company, to become Coca-Cola Enterprises Inc.
The longest running soda fountain that sold Coca-Cola was Fleeman’s pharmacy, established
in 1914 and existed for 81 years until 1995.
On July 12, 1944, the one-billionth gallon of Coca-Cola syrup was produced.
In 1955 the Coca-Cola cans were first introduced.
On April 23, 1985, Coca-Cola tried to change the formula of the syrup by preparing “New
Coke”.
Subsequent taste tests showed that people loved the taste of New coke better than Coke
or Pepsi and the company went on to produce more of it.
Soon after, the public wanted the old Coca-Cola soda back.
The Coca-Cola Company granted the wish of the public and produced the old drink with
a slight variation in the main sweetener; using high fructose corn syrup instead of
cane sugar.
This new drink was produced under the name Coca-Cola Classic on July 10, 1985.
Coca Cola in Recent Years On July 5, 2005, it was announced that Coca-Cola
would resume production in Iraq for the first time since the Arab league refused its use
in 1968.
By April 2007, Canada removed the “Classic” from the name, as New Coke was no longer in
production, so there was no need to differentiate between the two kinds of coke.
In 2009, Coca-Cola introduced the 7.5-ounce mini can.
Also in 2009, the “Classic” was removed from the 470 ml bottles of Coca-Cola sold in the
South Eastern United States and in 2011; “Classic” was removed from all Coca-Cola products.
In September 2011, the Coca Cola Company announced price reductions asking retailers to sell
eight packs at $2.99.
That same day, the company announced that the 12.5 ounces would sell at 89 cents and
the 16 ounces would sell at 99 cents.
In 2012, Coca-Cola resumed operations in Myanmar after 60 years of absence due to investment
sanction imposed on the US.
In 2013, the company announced that Coca-Cola Life would be introduced to Argentina and
other parts of the world.
This drink contained stevia and sugar but the production of Coca-Cola Life was discontinued
in Britain in June 2017.
Coca-Cola together with its investors is working to invest $5billion in their operations in
India by 2020.
Presently, The Coca-Cola Company owns several outlets around the world with the headquarters
situated as a 29 story; 403-foot tall building in Atlanta, Georgia called the One Coca-Cola
Plaza.
As of 2017, the company employed 61,800 members of staff with Muhtar Kent as the Chairman
of the Board and James Quincey as the President and Chief Executive Officer.
The net income in 2017 estimated around $1.4 billion with total assets worth $87.8 billion
and estimated net worth around $180 billion.

With more than 30,000 cafes around the globe, Starbucks has become a well known name across the world. From its iconic and popular cups with espresso inside them, Starbucks evolved from on coffee bean shop in Seattle to a brand with $80 billion business over 48 years. Starbucks cover total of 57% sales in the cafe market.
You heard it right!!
57% is not a small number. Nearly 2/3 of the coffee sold in the U.S. comes from Starbucks. But this itself has come with real pains. With 14,000 locations in U.S. alone, Starbucks has spread itself too thin.
Having too many stores out there led to fewer transactions in individual stores. To compensate the loss of fewer transactions, the company tried to increase the prices of their products. Doing this frequently can drive the customers away.
So, what strategy did Starbucks use to attract its customers ?
This was the time of 1970. Three college friends Zev Siegl, Jerry Baldwin and Gordon Bowker decided to go for a coffee business. They found a mentor in Alfred Peet, founder of Peet’s coffee and the man behind the custom coffee roasting to the U.S. So, with the help of Peet, the three friends founded Starbucks , a coffee bean shop and roastery at Seattle’s famous Pike Place Market in 1971. Peet helped those young entrepreneurs with coffee beans and helped them to connect with coffee brokers to provide the source to get their own roasted coffee beans until they could set up their own roastery. For the first decade, the founders opened the branches of Starbucks at 5 locations. At that time, the conventions coffee consumers found out a glaring absence that was actual coffee drinks or the actual cups made especially for coffee. There was no actual bars and no such demand for espresso based drink at that period of time. People usually take coffee beans their homes and just with simple method, they used to brew the coffee. No one had the thought of getting a beverage at a Starbucks coffee shop until 1980. Initial focus of Starbucks was the high quality coffee as customers were more focused on the canned coffee. The company hired its first Director of Marketing and Sales, Howard Schultz. That man was very professional to the level where he became the CEO of Starbucks later.
In 1983, Schultz went To Italy and returns with an idea that was turning the coffee bean stores into cafes. Starbucks launched its first latte the next year. That experiment was a success and four years later Schultz partnered with the investors and bought Starbucks with $3.8 million. Schultz proposed a strategy of aggressive expansion.
By 1996, the company had opened the cafes in the more than thousand locations including the international cafes in Japan and Singapore.
Growth was too rapid in the case of Starbucks that in just three years later, the company opened the café in 2000th location as well.
Schultz switched from CEO to Executive Chairman at 2000. Between 2000 and 2007, Starbucks witnessed the extreme growth that the number of its cafes got more than quadrupled like 3,500 to 15,000 cafes directly.
Sales hot up from $2 billion to $9.4 billion in that period. But then Starbucks hit a wall.
The 2007 financial crash:
The growth from that year remained constant. The stock price fell by 50 percent. So Starbucks brought back Howard Schultz.
This news alone raised the Starbucks stock by 9 percent. He laid off 6,700 baristas in the café. He wanted customers to remember his brand. Schultz ordered all the cafes in the U.S. locations to call off in the afternoon so that he could show the baristas how to make the signature espresso. He wanted to make the customers to experience real life coffee in the stores to let it remember fresh in their minds. Schultz even ordered to remove automatic espresso machines.
Schultz’s strategy worked and the company stock price soared up by 149 percent in 2009. The company has been gaining positive reviews since then.
Starbucks took the big step of opening the new kind of stores that are Starbucks Reserve Roasteries. These massive foot stores are designed to be a tourist destination. Here, Starbucks baristas experiment new and different brewing methods to come up with delicious beverages. With this , Starbucks decided to come up with something new for the customers every now and then.
Wireless PANs (WPANs) have caused the latest revolution in wireless technology. WPAN’s are short to very short-range (from a couple of centimeters to a couple of meters) wireless networks that can use to exchange information between devices within reach of an individual. WPANs can be used to replace cables between computers and peripherals; share multimedia content amongst devices; build an infrastructure for sensor networking applications, or establish various location-aware services. The best example represents Wireless Personal Area Networks in the industry-standard Bluetooth found in many consumer electronics such as cell phones, PDAs, wireless headsets, wireless mouse, and wireless keyboards.

Personal Area Networks(PAN’s) was first demonstrated by IBM researchers in 1996 that utilized the human body to exchange digital information. Engineers use picoamp currents through the body at very low frequencies of around 1MHz. The low power and frequencies prevented eavesdropping and interference to neighboring PAN’s. In this way, they created a new way to communicate between body-borne appliances by using the human body as a channel. The only Limitation was that some form of human contact between devices is required, which may not always be desirable or possible. To get around this problem of human contact, other alternatives such as IR(Infrared) or Far-field (radio) communications have been considered. Using wireless methods such as IR or radio frequency (RF) for PAN’s is known as WPAN, which are typically smaller, operate on battery power, and either worn on a human body or carried personally. The main design goal of WPANs is to allow either stationary or moving devices that are close to communicating and exchanging information without wires. WPANs should allow devices to create or provide data/voice access points is within a Personal Operating Space(POS) of up to 10 meters in all directions and envelops a stationary or a mobile person.

The WPANs systems are currently expected to provide secure modes of operation, allowing groups of personal devices to interconnect while excluding connectivity to other non-essentials. They should not affect the primary function, the form factor, and power consumption of the devices in which they are embedded. As WPANs primarily use the license-free radio frequencies (e.g., ISM band), they have to coexist with other RF technologies that make of these frequencies. A WPAN is functionally similar to a WLAN while it differs in power consumption, coverage range rate, and cost.
Pluto (minor-planet designation: 134340 Pluto) is a dwarf planet in the Kuiper belt, a ring of bodies beyond the orbit of Neptune. It was the first and the largest Kuiper belt object to be discovered. After Pluto was discovered in 1930, it was declared to be the ninth planet from the Sun. Beginning in the 1990s, its status as a planet was questioned following the discovery of several objects of similar size in the Kuiper belt and the scattered disc, including the dwarf planet Eris. This led the International Astronomical Union (IAU) in 2006 to formally define the term planet excluding Pluto and reclassifying it as a dwarf planet.


Pluto is the ninth-largest and tenth-most-massive known object directly orbiting the Sun. It is the largest known trans-Neptunian object by volume but is less massive than Eris. Like other Kuiper belt objects, Pluto is primarily made of ice and rock and is relatively small—one-sixth the mass of the Moon and one-third its volume. It has a moderately eccentric and inclined orbit during which it ranges from 30 to 49 astronomical units or AU (4.4–7.4 billion km) from the Sun. This means that Pluto periodically comes closer to the Sun than Neptune, but a stable orbital resonance with Neptune prevents them from colliding. Light from the Sun takes 5.5 hours to reach Pluto at its average distance (39.5 AU).
Pluto has five known moons: Charon (the largest, with a diameter just over half that of Pluto), Styx, Nix, Kerberos, and Hydra. Pluto and Charon are sometimes considered a binary system because the barycenter of their orbits does not lie within either body.
The New Horizons spacecraft performed a flyby of Pluto on July 14, 2015, becoming the first and, to date, only spacecraft to do so. During its brief flyby, New Horizons made detailed measurements and observations of Pluto and its moons. In September 2016, astronomers announced that the reddish-brown cap of the north pole of Charon is composed of tholins, organic macromolecules that may be ingredients for the emergence of life, and produced from methane, nitrogen and other gases released from the atmosphere of Pluto and transferred 19,000 km (12,000 mi) to the orbiting moon.
Orbit :

Pluto was discovered in 1930 near the star δ Geminorum, and merely coincidentally crossing the ecliptic at this time of discovery. Pluto moves about 7 degrees east per decade with small apparent retrograde motion as seen from Earth. Pluto was closer to the Sun than Neptune between 1979 and 1999.

Pluto’s orbital period is currently about 248 years. Its orbital characteristics are substantially different from those of the planets, which follow nearly circular orbits around the Sun close to a flat reference plane called the ecliptic. In contrast, Pluto’s orbit is moderately inclined relative to the ecliptic (over 17°) and moderately eccentric (elliptical). This eccentricity means a small region of Pluto’s orbit lies closer to the Sun than Neptune’s. The Pluto–Charon barycenter came to perihelion on September 5, 1989, and was last closer to the Sun than Neptune between February 7, 1979, and February 11, 1999.

Although the 3:2 resonance with Neptune (see below) is maintained, Pluto’s inclination and eccentricity behave in a chaotic manner. Computer simulations can be used to predict its position for several million years (both forward and backward in time), but after intervals much longer than the Lyapunov time of 10–20 million years, calculations become unreliable: Pluto is sensitive to immeasurably small details of the Solar System, hard-to-predict factors that will gradually change Pluto’s position in its orbit.
Rotation:
Pluto’s rotation period, its day, is equal to 6.387 Earth days. Like Uranus, Pluto rotates on its “side” in its orbital plane, with an axial tilt of 120°, and so its seasonal variation is extreme; at its solstices, one-fourth of its surface is in continuous daylight, whereas another fourth is in continuous darkness.The reason for this unusual orientation has been debated. Research from the University of Arizona has suggested that it may be due to the way that a body’s spin will always adjust to minimise energy. This could mean a body reorienting itself to put extraneous mass near the equator and regions lacking mass tend towards the poles. This is called polar wander. According to a paper released from the University of Arizona, this could be caused by masses of frozen nitrogen building up in shadowed areas of the dwarf planet. These masses would cause the body to reorient itself, leading to its unusual axial tilt of 120°. The buildup of nitrogen is due to Pluto’s vast distance from the Sun. At the equator, temperatures can drop to −240 °C (−400.0 °F; 33.1 K), causing nitrogen to freeze as water would freeze on Earth. The same effect seen on Pluto would be observed on Earth were the Antarctic ice sheet several times larger.
Atmosphere:

Pluto has a tenuous atmosphere consisting of nitrogen (N2), methane (CH4), and carbon monoxide (CO), which are in equilibrium with their ices on Pluto’s surface. According to the measurements by New Horizons, the surface pressure is about 1 Pa (10 μbar),roughly one million to 100,000 times less than Earth’s atmospheric pressure.

It was initially thought that, as Pluto moves away from the Sun, its atmosphere should gradually freeze onto the surface; studies of New Horizons data and ground-based occultations show that Pluto’s atmospheric density increases, and that it likely remains gaseous throughout Pluto’s orbit. New Horizons observations showed that atmospheric escape of nitrogen to be 10,000 times less than expected.Alan Stern has contended that even a small increase in Pluto’s surface temperature can lead to exponential increases in Pluto’s atmospheric density; from 18 hPa to as much as 280 hPa (three times that of Mars to a quarter that of the Earth). At such densities, nitrogen could flow across the surface as liquid.Just like sweat cools the body as it evaporates from the skin, the sublimation of Pluto’s atmosphere cools its surface.The presence of atmospheric gases was traced up to 1670 kilometers high; the atmosphere does not have a sharp upper boundary.
Satellites:

Pluto has five known natural satellites. The closest to Pluto is Charon. First identified in 1978 by astronomer James Christy, Charon is the only moon of Pluto that may be in hydrostatic equilibrium. Charon’s mass is sufficient to cause the barycenter of the Pluto–Charon system to be outside Pluto. Beyond Charon there are four much smaller circumbinary moons. In order of distance from Pluto they are Styx, Nix, Kerberos, and Hydra. Nix and Hydra were both discovered in 2005, Kerberos was discovered in 2011,and Styx was discovered in 2012.The satellites’ orbits are circular (eccentricity < 0.006) and coplanar with Pluto’s equator (inclination < 1°),and therefore tilted approximately 120° relative to Pluto’s orbit. The Plutonian system is highly compact: the five known satellites orbit within the inner 3% of the region where prograde orbits would be stable.

Origin:

Pluto’s origin and identity had long puzzled astronomers. One early hypothesis was that Pluto was an escaped moon of Neptune knocked out of orbit by Neptune’s largest current moon, Triton. This idea was eventually rejected after dynamical studies showed it to be impossible because Pluto never approaches Neptune in its orbit.
Pluto’s true place in the Solar System began to reveal itself only in 1992, when astronomers began to find small icy objects beyond Neptune that were similar to Pluto not only in orbit but also in size and composition. This trans-Neptunian population is thought to be the source of many short-period comets. Pluto is now known to be the largest member of the Kuiper belt,a stable belt of objects located between 30 and 50 AU from the Sun. As of 2011, surveys of the Kuiper belt to magnitude 21 were nearly complete and any remaining Pluto-sized objects are expected to be beyond 100 AU from the Sun. Like other Kuiper-belt objects (KBOs), Pluto shares features with comets; for example, the solar wind is gradually blowing Pluto’s surface into space.It has been claimed that if Pluto were placed as near to the Sun as Earth, it would develop a tail, as comets do.This claim has been disputed with the argument that Pluto’s escape velocity is too high for this to happen. It has been proposed that Pluto may have formed as a result of the agglomeration of numerous comets and Kuiper-belt objects.

Bitcoin is basically a computer file which is stored in a digital wallet app on a smartphone or computer. People can send Bitcoins or part of one to your digital wallet, and you can send Bitcoins to other people.You can buy Bitcoins using real money. You can sell things and let people pay you with Bitcoins.The money you put into Bitcoin is not safe from value fluctuations. Bitcoin is a volatile investment. If you’re looking for a “safe” investment with guaranteed returns, then don’t invest in Bitcoin

Bitcoin is the oldest cryptocurrency in the world. It is a digital currency that is often used to exchange value for goods and services. Bitcoins work on the principle of blockchain technology. Bitcoins can also be mined or produced using a massive computing system, complex technical process, and an active internet connection.People have traded in Bitcoin for over a decade now. Many companies have even started accepting Bitcoins as a payment method. The price of the coins has gone up substantially over the years.

In April 2018, the RBI had effectively banned cryptocurrency transactions via banks and e-wallets in the country. It was initially supported by the Supreme Court, though the top court later quashed the ban in March last year.Earlier this week, the government listed a bill titled The Cryptocurrency and Regulation of Official Digital Currency Bill, 2021 that is aimed to provide a framework for creation of an official digital currency to be issued by the RBI and prohibit all existing private cryptocurrencies. Experts, however, believe that it would take some time for the country to bring any changes.

Bitcoin held at exchanges are vulnerable to theft through phishing, scamming, and hacking. As of December 2017, around 980,000 bitcoins have been stolen from cryptocurrency exchanges.The use of bitcoin by criminals has attracted the attention of financial regulators, legislative bodies, law enforcement, and the media.Bitcoin gained early notoriety for its use on the Silk Road.
sensor is a device that produces an output signal for the purpose of sensing of a physical phenomenon.

In the broadest definition, a sensor is a device, module, machine, or subsystem that detects events or changes in its environment and sends the information to other electronics, frequently a computer processor. Sensors are always used with other electronics.
Sensors are used in everyday objects such as touch-sensitive elevator buttons (tactile sensor) and lamps which dim or brighten by touching the base, and in innumerable applications of which most people are never aware. With advances in micromachinery and easy-to-use microcontroller platforms, the uses of sensors have expanded beyond the traditional fields of temperature, pressure and flow measurement, for example into MARG sensors.
Analog sensors such as potentiometers and force-sensing resistors are still widely used. Their applications include manufacturing and machinery, airplanes and aerospace, cars, medicine, robotics and many other aspects of our day-to-day life. There is a wide range of other sensors that measure chemical and physical properties of materials, including optical sensors for refractive index measurement, vibrational sensors for fluid viscosity measurement, and electro-chemical sensors for monitoring pH of fluids.
A sensor’s sensitivity indicates how much its output changes when the input quantity it measures changes. For instance, if the mercury in a thermometer moves 1 cm when the temperature changes by 1 °C, its sensitivity is 1 cm/°C (it is basically the slope dy/dx assuming a linear characteristic). Some sensors can also affect what they measure; for instance, a room temperature thermometer inserted into a hot cup of liquid cools the liquid while the liquid heats the thermometer. Sensors are usually designed to have a small effect on what is measured; making the sensor smaller often improves this and may introduce other advantages.
Technological progress allows more and more sensors to be manufactured on a microscopic scale as microsensors using MEMS technology. In most cases, a microsensor reaches a significantly faster measurement time and higher sensitivity compared with macroscopic approaches. Due to the increasing demand for rapid, affordable and reliable information in today’s world, disposable sensors low-cost and easy‐to‐use devices for short‐term monitoring or single‐shot measurements have recently gained growing importance. Using this class of sensors, critical analytical information can be obtained by anyone, anywhere and at any time, without the need for recalibration and worrying about contamination.
Classification of measurement errors:

A good sensor obeys the following rules:
* it is sensitive to the measured property
* it is insensitive to any other property likely to be encountered in its application, and
* it does not influence the measured property.
Most sensors have a linear transfer function. The sensitivity is then defined as the ratio between the output signal and measured property. For example, if a sensor measures temperature and has a voltage output, the sensitivity is a constant with the units [V/K]. The sensitivity is the slope of the transfer function. Converting the sensor’s electrical output (for example V) to the measured units (for example K) requires dividing the electrical output by the slope (or multiplying by its reciprocal). In addition, an offset is frequently added or subtracted. For example, −40 must be added to the output if 0 V output corresponds to −40 C input.
For an analog sensor signal to be processed, or used in digital equipment, it needs to be converted to a digital signal, using an analog-to-digital converter.
Sensor deviations :

Since sensors cannot replicate an ideal transfer function, several types of deviations can occur which limit sensor accuracy:
* Since the range of the output signal is always limited, the output signal will eventually reach a minimum or maximum when the measured property exceeds the limits. The full scale range defines the maximum and minimum values of the measured property.[citation needed]
* The sensitivity may in practice differ from the value specified. This is called a sensitivity error. This is an error in the slope of a linear transfer function.
* If the output signal differs from the correct value by a constant, the sensor has an offset error or bias. This is an error in the y-intercept of a linear transfer function.
* Nonlinearity is deviation of a sensor’s transfer function from a straight line transfer function. Usually, this is defined by the amount the output differs from ideal behavior over the full range of the sensor, often noted as a percentage of the full range.
* Deviation caused by rapid changes of the measured property over time is a dynamic error. Often, this behavior is described with a bode plot showing sensitivity error and phase shift as a function of the frequency of a periodic input signal.
* If the output signal slowly changes independent of the measured property, this is defined as drift. Long term drift over months or years is caused by physical changes in the sensor.
* Noise is a random deviation of the signal that varies in time.
* A hysteresis error causes the output value to vary depending on the previous input values. If a sensor’s output is different depending on whether a specific input value was reached by increasing vs. decreasing the input, then the sensor has a hysteresis error.
Resolution:
The sensor resolution or measurement resolution is the smallest change that can be detected in the quantity that it is being measured. The resolution of a sensor with a digital output is usually the numerical resolution of the digital output. The resolution is related to the precision with which the measurement is made, but they are not the same thing. A sensor’s accuracy may be considerably worse than its resolution.
For example, the distance resolution is the minimum distance that can be accurately measured by any distance measuring devices. In a time-of-flight camera, the distance resolution is usually equal to the standard deviation (total noise) of the signal expressed in unit of length.
The sensor may to some extent be sensitive to properties other than the property being measured. For example, most sensors are influenced by the temperature of their environment.
Chemical sensor:
A chemical sensor is a self-contained analytical device that can provide information about the chemical composition of its environment, that is, a liquid or a gas phase. The information is provided in the form of a measurable physical signal that is correlated with the concentration of a certain chemical species (termed as analyte). Two main steps are involved in the functioning of a chemical sensor, namely, recognition and transduction. In the recognition step, analyte molecules interact selectively with receptor molecules or sites included in the structure of the recognition element of the sensor. Consequently, a characteristic physical parameter varies and this variation is reported by means of an integrated transducer that generates the output signal. A chemical sensor based on recognition material of biological nature is a biosensor. However, as synthetic biomimetic materials are going to substitute to some extent recognition biomaterials, a sharp distinction between a biosensor and a standard chemical sensor is superfluous. Typical biomimetic materials used in sensor development are molecularly imprinted polymers and aptamers.
Biosensor:
In biomedicine and biotechnology, sensors which detect analytes thanks to a biological component, such as cells, protein, nucleic acid or biomimetic polymers, are called biosensors. Whereas a non-biological sensor, even organic (carbon chemistry), for biological analytes is referred to as sensor or nanosensor. This terminology applies for both in-vitro and in vivo applications. The encapsulation of the biological component in biosensors, presents a slightly different problem that ordinary sensors; this can either be done by means of a semipermeable barrier, such as a dialysis membrane or a hydrogel, or a 3D polymer matrix, which either physically constrains the sensing macromolecule or chemically constrains the macromolecule by bounding it to the scaffold.
Neuromorphic sensors :

Neuromorphic sensors are sensors that physically mimic structures and functions of biological neural entities.[8] One example of this is the event camera.
MOS sensors :
Metal-oxide-semiconductor (MOS) technology originates from the MOSFET (MOS field-effect transistor, or MOS transistor) invented by Mohamed M. Atalla and Dawon Kahng in 1959, and demonstrated in 1960. MOSFET sensors (MOS sensors) were later developed, and they have since been widely used to measure physical, chemical, biological and environmental parameters.
Biochemical sensors:

A number of MOSFET sensors have been developed, for measuring physical, chemical, biological and environmental parameters. The earliest MOSFET sensors include the open-gate field-effect transistor (OGFET) introduced by Johannessen in 1970, the ion-sensitive field-effect transistor (ISFET) invented by Piet Bergveld in 1970, the adsorption FET (ADFET) patented by P.F. Cox in 1974, and a hydrogen-sensitive MOSFET demonstrated by I. Lundstrom, M.S. Shivaraman, C.S. Svenson and L. Lundkvist in 1975. The ISFET is a special type of MOSFET with a gate at a certain distance, and where the metal gate is replaced by an ion-sensitive membrane, electrolyte solution and reference electrode. The ISFET is widely used in biomedical applications, such as the detection of DNA hybridization, biomarker detection from blood, antibody detection, glucose measurement, pH sensing, and genetic technology.
Image sensors:

MOS technology is the basis for modern image sensors, including the charge-coupled device (CCD) and the CMOS active-pixel sensor (CMOS sensor), used in digital imaging and digital cameras. Willard Boyle and George E. Smith developed the CCD in 1969. While researching the MOS process, they realized that an electric charge was the analogy of the magnetic bubble and that it could be stored on a tiny MOS capacitor. As it was fairly straightforward to fabricate a series of MOS capacitors in a row, they connected a suitable voltage to them so that the charge could be stepped along from one to the next. The CCD is a semiconductor circuit that was later used in the first digital video cameras for television broadcasting.
The MOS active-pixel sensor (APS) was developed by Tsutomu Nakamura at Olympus in 1985.The CMOS active-pixel sensor was later developed by Eric Fossum and his team in the early 1990s.
Monitoring sensors:

MOS monitoring sensors are used for house monitoring, office and agriculture monitoring, traffic monitoring (including car speed, traffic jams, and traffic accidents), weather monitoring (such as for rain, wind, lightning and storms), defense monitoring, and monitoring temperature, humidity, air pollution, fire, health, security and lighting.MOS gas detector sensors are used to detect carbon monoxide, sulfur dioxide, hydrogen sulfide, ammonia, and other gas substances.Other MOS sensors include intelligent sensors and wireless sensor network (WSN) technology

The Kaveri is an Indian river flowing through the states of Karnataka and Tamil Nadu. The Cauvery River rises in the Western Ghats and flows in eastwardly direction passing through the states of Karnataka, Tamil Nadu, Kerala and Pondicherry before it drains into Bay of Bengal.The total length of the river from source to its outfall into Bay of Bengal is about 800 km.The Cauvery basin extends over states of Tamil Nadu, Karnataka, Kerala and Union Territory of Puducherry draining an area of 81,155 Sq.km which is nearly 2.7% of the total geographical area of the country with a maximum length and width of about 560 km and 245 km.

Cauvery river is the largest river in tamil nadu occupying 765 km.The Kaveri is a sacred river to the people of South India and is worshipped as the Goddess Kaveriamma. The primary uses of the Kaveri is providing water for irrigation, water for household consumption and the generation of electricity.In February 2020, Tamil Nadu assembly passed bill to declare Cauvery Delta as Protected Agricultural Zone, includes Thanjavur, Thirvarur, Nagapattinam and five blocks in Cuddalore and Pudukottai. The bill fails to include Tiruchirappalli, Ariyalur and Karur which are geographically included in the Cauvery Delta.The cauvery river is the main source for the delta region for irrigation.It ends in the bay of Bengal.
On 22 June 2018, despite opposition from Karnataka, the Central government constituted the Cauvery Water Regulation Committee (CWRC) as per the provisions in the Kaveri Management Scheme laid down by the Supreme Court.
Acting on the Supreme Court’s direction, the Centre constituted a Cauvery Water Management Authority (CWMA) on 1 June 2018 to address the dispute over sharing of river water among Tamil Nadu, Karnataka, Kerala and Puducherry.The central government failed to adhere with the top court’s deadline of within six weeks of deliverance of judgement.
You got your pay-check in the end of the month. Congrats!! But now what? Either spend it or save it. Now, you know the things on which you want to spend the money. But a lot of people don’t know how to save money in such a way where the money they saved does not lose its value but in reality let it increase. Now, you must have this in your mind – How?
Simple, through investing it. There are four different areas where people usually invest in our country. First is Savings Account, second is Fixed Deposit, third is Gold or Jewellery and the last is real estate. Another way is investing in the stock market where the risk is comparatively higher.
Every investment contains three aspects viz. Return, Time and Risk.
Return is basically the profit you actually get through your investment and make sure that the profit percentage is higher than the inflation rate in your area otherwise the investment that you make would not make any sense.
Risk is about the chance of how much money can you lose through your investment. What are the chances of going in loss after investing in certain area , this mainly come under the risk aspect.
Time is about for how long are you planning to invest.
Savings account has the minimum risk with no restriction. You can take or save your money at any time. But the return is something in savings account which you have to compromise. In simply words, ROI ( Return In Investment ) in this case is low.
Fixed deposit is also another less risky option but there is a time limit here in which you can not take your money out. But the return here is slightly higher than that of savings account.
There is no risk in investing in Gold and Jewellery but ROI is not confirmed as their prices fluctuate a lot.
Investing in real estate depends on a lot of factors especially the area. There is a low to moderate risk in investing it. As the fluctuation of prices prevail here as well. You need a lot of capital as well in order to invest in the real estate.
Investment into the stocks may lead to higher return and higher loss as well. It depends on the stock in which you are investing.
It is advised to invest in multiple arenas in order to avoid higher risks.
What are Mutual Funds?
It is a special kind of investment through which you can invest on different types together. It is a better way of diversifying your investments by investing in a one place.
An asset management company collects money from different investors. Afterwards, it invests that money in different places. The collectively return that it gets is given to you after deducting small percent of it for the company itself. A lot of organisations have their own asset management companies. The risk and return all depends on which kind of mutual funds you are investing in.
Types of mutual funds:
There can be different types of mutual funds according to the places on which asset management company is investing.
Equity Mutual funds:
In equity mutual funds, money is invested in the stock market. In this category, generally risks and return both are high. If the investment in big company then it is called large cap equity fund and so on.
Diversified Equity Fund:
Here the investment is done in the large cap, medium cap and small cap companies simultaneously or it is done in different companies.
Equity Linked Saving Scheme (ELSS):
In this scheme you can save your tax that you get in the profit. The fund manager purposedly invests in the places where there is large return and large risks.
Index Funds:
Index funds are passively managed fund where no agent of asset management company looks for the places to invest. The return on these funds depend on the market price.
Debt Investment:
These are mutual funds which are invested in debt instruments like bonds, debentures and certificate of deposits.
What are bonds?
When government borrows money from people as loans then that is called a bond. The government will return the money to you with a fixed interest.
Hybrid Mutual funds:
In this type, the money is invested in both equity and debt mutual funds.
For investing the money, you should gather the complete information about the type of investment you want to make first. Afterwards, make the right decision. But don’t let your money to sit idle in the banks.
Introduction:-
Data science is an interdisciplinary field that uses scientific methods, processes, algorithms and systems to extract knowledge and insights from noisy, structured and unstructured data, and apply knowledge and actionable insights from data across a broad range of application domains. Data science is related to data mining, machine learning and big data.

Data science is a “concept to unify statistics, data analysis, informatics, and their related methods” in order to “understand and analyze actual phenomena” with data. It uses techniques and theories drawn from many fields within the context of mathematics, statistics, computer science, information science, and domain knowledge. However, data science is different from computer science and information science. Turing Award winner Jim Gray imagined data science as a “fourth paradigm” of science (empirical, theoretical, computational, and now data-driven) and asserted that “everything about science is changing because of the impact of information technology” and the data deluge.
A data scientist is someone who creates programming code, and combines it with statistical knowledge to create insights from data.
Foundations:
Data science is an interdisciplinary field focused on extracting knowledge from data sets, which are typically large (see big data), and applying the knowledge and actionable insights from data to solve problems in a wide range of application domains.The field encompasses preparing data for analysis, formulating data science problems, analyzing data, developing data-driven solutions, and presenting findings to inform high-level decisions in a broad range of application domains. As such, it incorporates skills from computer science, statistics, information science, mathematics, information visualization, data integration, graphic design, complex systems, communication and business.Statistician Nathan Yau, drawing on Ben Fry, also links data science to human-computer interaction: users should be able to intuitively control and explore data.In 2015, the American Statistical Association identified database management, statistics and machine learning, and distributed and parallel systems as the three emerging foundational professional communities.
Relationship to statistics :
Many statisticians, including Nate Silver, have argued that data science is not a new field, but rather another name for statistics. Others argue that data science is distinct from statistics because it focuses on problems and techniques unique to digital data.Vasant Dhar writes that statistics emphasizes quantitative data and description. In contrast, data science deals with quantitative and qualitative data (e.g. images) and emphasizes prediction and action.Andrew Gelman of Columbia University has described statistics as a nonessential part of data science. Stanford professor David Donoho writes that data science is not distinguished from statistics by the size of datasets or use of computing, and that many graduate programs misleadingly advertise their analytics and statistics training as the essence of a data science program. He describes data science as an applied field growing out of traditional statistics.In summary, data science can be therefore described as an applied branch of statistics.
Etymology:
In 1962, John Tukey described a field he called “data analysis“, which resembles modern data science. In 1985, in a lecture given to the Chinese Academy of Sciences in Beijing, C.F. Jeff Wu used the term Data Science for the first time as an alternative name for statistics.Later, attendees at a 1992 statistics symposium at the University of Montpellier II acknowledged the emergence of a new discipline focused on data of various origins and forms, combining established concepts and principles of statistics and data analysis with computing.
The term “data science” has been traced back to 1974, when Peter Naur proposed it as an alternative name for computer science.In 1996, the International Federation of Classification Societies became the first conference to specifically feature data science as a topic. However, the definition was still in flux. After the 1985 lecture in the Chinese Academy of Sciences in Beijing, in 1997 C.F. Jeff Wu again suggested that statistics should be renamed data science. He reasoned that a new name would help statistics shed inaccurate stereotypes, such as being synonymous with accounting, or limited to describing data.In 1998, Hayashi Chikio argued for data science as a new, interdisciplinary concept, with three aspects: data design, collection, and analysis.
During the 1990s, popular terms for the process of finding patterns in datasets (which were increasingly large) included “knowledge discovery” and “data mining”.
Modern usage:
The modern conception of data science as an independent discipline is sometimes attributed to William S. Cleveland. In a 2001 paper, he advocated an expansion of statistics beyond theory into technical areas; because this would significantly change the field, it warranted a new name.”Data science” became more widely used in the next few years: in 2002, the Committee on Data for Science and Technology launched Data Science Journal. In 2003, Columbia University launched The Journal of Data Science. In 2014, the American Statistical Association’s Section on Statistical Learning and Data Mining changed its name to the Section on Statistical Learning and Data Science, reflecting the ascendant popularity of data science.
The professional title of “data scientist” has been attributed to DJ Patil and Jeff Hammerbacher in 2008. Though it was used by the National Science Board in their 2005 report, “Long-Lived Digital Data Collections: Enabling Research and Education in the 21st Century,” it referred broadly to any key role in managing a digital data collection.
Market:
Big data is becoming a tool for businesses and companies of all sizes. The availability and interpretation of big data has altered the business models of old industries and enabled the creation of new ones.Data scientists are responsible for breaking down big data into usable information and creating software and algorithms that help companies and organizations determine optimal operations.

There are people in the world who are having high income but are still living petty lives as they don’t know how to manage their finances.
Can you be financially secure even if you are not making a lot of money?
Can ordinary people invest in the stock market with manageable risks?
Answers to these questions are YES if you are well versed with Financial literacy.
Today managing money in a beneficial way has become a skill. It all starts with the income or money you are making in present. It can be through your salary or investments.
INCOME-
Your first step towards becoming a financial literate is to have enough money to manage. How can you make money now? For making money, you have to create your own value in the market. Employers would never hire YOU but they will hire your SKILLS. When you are imparting skills in yourself then you are creating your value. The more and better skills you have the more the value you would have.
EXPENSES-
When you get your income then what is the first thing you do?
Of course you either save it or spend it. In most of the times, you spend your income first. Now, how, when and on what to spend your income are the important aspects of financial literacy. Do you even know where your all money goes?
There is a 50:30:20 rule where 50% of your income goes to your urgent costs that can’t be delayed for example monthly bills including housing or rent other 30% of your income goes to Debt or savings and the rest 20% goes to your entertainment or the things you like to do or buy. If you don’t manage your expenses carefully then the repercussions only contain the regrets. People should note down their financial priorities every month then spend the income accordingly.
ASSETS-
Assets are the things on which you have the ownership. Everything from your house and saving accounts to your car are regarded as your assets. It is advised to develop the habit of saving from as earlier as possible while earning. Even if you save a very little amount then also this is not the problem. The thing is you should save and get into the practice of saving. Save regularly for any upcoming unexpected expenditures. Save as much to build more and more assets. After saving, make a diverse financial plan through which you can efficiently use your income.
STOCKS-
Investment nowadays has become a necessity. Your one portion of your income ought to be used to buy a stock as to open multiple ways to earn money. There is always some amount of risk while buying a stock as the company in which you are investing may get profits in future or maybe not. So, you have to choose the company wisely in which you are investing. For a beginner, it is advised to invest in index funds or mutual funds. A mutual fund is a professionally managed portfolio for investment that pulls money from all sorts of investors especially for those who are looking for diversifying their investments. Index funds are which are able to manage the performance for a group of companies like a group of tech companies or group of consumer goods company etc. An index basically consists of a basket of companies related to a particular niche. There are a lot of indices out there which can grab your attention. There comes the role of financial literacy which helps you to understand the tools required for achieving the short- term goals, intermediate goals or long-term goals.
LIABILITIES –
Liability is basically the debt you owe to a person or a business. Buying something with credit that is an asset and consuming something with credit has a vast difference. Using your student loan to go for a trip or investing your student loan to build assets and to hone your skills create a big impact in your life. Whether you use your money to invest on yourself or spend it on having fun, it all depends on you and your mindset. The worse repercussions of more debt than your income have all been emotional. They suck all the joy of one’s life. Try to limit your expenses and liabilities. In the end, it all depends on you whether you make right choices or wrong. These choices can be related to money , education and relationships etc. Every choice you make has an impact in your life. It does not matter whether the impact is large or small. So, choose wisely!

A podcast is an episode of series of spoken digital audio file. Podcasting is one of the most significant tools accessible to build your brand and your audience. when it comes to creating a podcast, the real magic happens when you’re recording.
Here are few ways to make your podcast sound more professional are enlisted below:
1.Start with an introduction:
Always start with an intro. It’s nice for stigmatization functions, however there are alternative ways to approach it. this is your show. You can do whatever it is that you want to do with it. You have a lot of freedom here. Now, like any podcast, video, or perhaps a live presentation, the simplest factor you’ll do at the start is to inform your listeners or readers what they’re about to experience. This helps them perceive what to expect, and provides them one thing to seem forward to. Then I pay a couple of minute going over about what I’m reaching to observe and who I actually have on the show as a guest that episode.Intro is an important step taken into consideration.
2. Attract the audience with an outro:
Always keep this one quick and sweet. In addition, in your intro, your outro could be very essential. And frankly, I see a variety of podcasters lacking in this one. your outro is the closing component humans pay attention and bear in mind whilst they are paying attention to you. So placed it to precise use.
3. Remove Interruptions during podcasting:
Ambient noises have an area in suggests however must be deliberate and now no longer left to chance. You don’t need your listener to listen a baby within side the subsequent room, a truck noise outside, or a noisy air conditioner.
It makes the whole listening enjoy unpleasant, and also you need to keep away from it in any respect costs. Customer enjoy is one of the primary elements whilst Clients purchase and pay, so that you need to take note of how does your podcast sound.
Podcasts are regularly listened to in cars, perks or gym, in the course of a commute, etc. Those aren’t ideal listening situations and are complete of noises. you must make your audio crystal clean to assure your podcast sound more professional. Another simple way is to record in a better condition simply is to observe patterns in the neighborhood whenever you are recording. In most places, it is the quietest during morning hours.
4. Adjust your tone:
There are many ways for podcasters, you ought to put in force to make your podcast sound professionally.
5.Submit Social Proofs:
If you have clients, submit their genuine testimonials. The people you have helped submit their positive testimonials if your product resolved their issues. Simply raise and share it.
When you don’t have customers yet, present the benefits of your product in a larger context. Build your credibility on the basis of years of unique work, knowledge, certifications, qualifications and experience.
Over 50 to 70 % of audiences read reviews before making a buying decision.
And nearly 63% of consumers are more likely to buy from a site that has ratings and reviews.
For instance, if you have a podcast about electric vehicles and not be an engineer. always make sure your podcast sounds professional, it shows how reputable companies are implementing the technologies. Proving that someone with authority did what you are talking about shows that you know your topic. When you teach something, try to show how it works for others.

A computer is a programmable device that stores, retrieves, and processes data. … The term was later given to mechanical devices as they began replacing human computers. Today’s computers are electronic devices that accept data (input), process that data, produce output, and store storage the results.A computer is a machine that can store and process information. Most computers rely on a binary system, which uses two variables, 0 and 1, to complete tasks such as storing data, calculating algorithms, and displaying information.Computer has become very important nowadays because it is very much accurate, fast and can accomplish many tasks easily.

TYPES OF COMPUTER:-
* ANALOG COMPUTER.
* DIGITAL COMPUTER.
* MAINFRAME COMPUTER.
ANALOG COMPUTER:-
An analog computer or analogue computer is a type of computer that uses the continuously variable aspects of physical phenomena such as electrical, mechanical, or hydraulic quantities to model the problem being solved planimeters, nomograms, operational amplifiers, mechanical integrators, slide rules, tide pool predators, electric integrators are some examples for analog computers.
DIGITAL COMPUTER:-
Digital computer, any of a class of devices capable of solving problems by processing information in discrete form. It operates on data, including magnitudes, letters, and symbols, that are expressed in binary codes using only the two digits 0 and 1.smartphones, calculators, tablets, personal computer are some examples for Digital computers.
MAINFRAME COMPUTER:-
A mainframe computer, informally called a mainframe or big iron, is a computer used primarily by large organizations for critical applications like bulk data processing for tasks such as censuses, industry and consumer statistics, enterprise resource planning, and large-scale transaction processing. IBM zSeries, System z9 and System z10 servers are some examples for Mainframe computers.
An aircraft is a vehicle or machine that is able to fly by gaining support from the air. It counters the force of gravity by using either static lift or by using the dynamic lift of an airfoil, or in a few cases the downward thrust from jet engines. Common examples of aircraft include airplanes, helicopters, airships (including blimps), gliders, paramotors, and hot air balloons.

The human activity that surrounds aircraft is called aviation. The science of aviation, including designing and building aircraft, is called aeronautics. Crewed aircraft are flown by an onboard pilot, but unmanned aerial vehicles may be remotely controlled or self-controlled by onboard computers. Aircraft may be classified by different criteria, such as lift type, aircraft propulsion, usage and others.

History :
Flying model craft and stories of manned flight go back many centuries; however, the first manned ascent and safe descent in modern times took place by larger hot-air balloons developed in the 18th century. Each of the two World Wars led to great technical advances. Consequently, the history of aircraft can be divided into five eras:
* Pioneers of flight, from the earliest experiments to 1914.
* First World War, 1914 to 1918.
Aviation between the World Wars, 1918 to 1939.
* Second World War, 1939 to 1945.
* Postwar era, also called the Jet Age, 1945 to the present day.
Methods of lift
Lighter than air – aerostats

Aerostats use buoyancy to float in the air in much the same way that ships float on the water. They are characterized by one or more large cells or canopies, filled with a relatively low-density gas such as helium, hydrogen, or hot air, which is less dense than the surrounding air. When the weight of this is added to the weight of the aircraft structure, it adds up to the same weight as the air that the craft displaces.
Small hot-air balloons, called sky lanterns, were first invented in ancient China prior to the 3rd century BC and used primarily in cultural celebrations, and were only the second type of aircraft to fly, the first being kites, which were first invented in ancient China over two thousand years ago.
During World War II, this shape was widely adopted for tethered balloons; in windy weather, this both reduces the strain on the tether and stabilizes the balloon. The nickname blimp was adopted along with the shape. In modern times, any small dirigible or airship is called a blimp, though a blimp may be unpowered as well as powered.
Heavier-than-air – aerodynes :

Heavier-than-air aircraft, such as airplanes, must find some way to push air or gas downwards so that a reaction occurs (by Newton’s laws of motion) to push the aircraft upwards. This dynamic movement through the air is the origin of the term. There are two ways to produce dynamic upthrust aerodynamic lift, and powered lift in the form of engine thrust.
Aerodynamic lift involving wings is the most common, with fixed-wing aircraft being kept in the air by the forward movement of wings, and rotorcraft by spinning wing-shaped rotors sometimes called rotary wings. A wing is a flat, horizontal surface, usually shaped in cross-section as an aerofoil. To fly, air must flow over the wing and generate lift. A flexible wing is a wing made of fabric or thin sheet material, often stretched over a rigid frame. A kite is tethered to the ground and relies on the speed of the wind over its wings, which may be flexible or rigid, fixed, or rotary.
Fixed-wing:

The forerunner of the fixed-wing aircraft is the kite. Whereas a fixed-wing aircraft relies on its forward speed to create airflow over the wings, a kite is tethered to the ground and relies on the wind blowing over its wings to provide lift. Kites were the first kind of aircraft to fly and were invented in China around 500 BC. Much aerodynamic research was done with kites before test aircraft, wind tunnels, and computer modelling programs became available.
The first heavier-than-air craft capable of controlled free-flight were gliders. A glider designed by George Cayley carried out the first true manned, controlled flight in 1853.
The practical, powered, fixed-wing aircraft (the airplane or aeroplane) was invented by Wilbur and Orville Wright
Rotorcraft:

Rotorcraft, or rotary-wing aircraft, use a spinning rotor with aerofoil section blades (a rotary wing) to provide lift. Types include helicopters, autogyros, and various hybrids such as gyrodynes and compound rotorcraft.
Helicopters have a rotor turned by an engine-driven shaft. The rotor pushes air downward to create lift. By tilting the rotor forward, the downward flow is tilted backward, producing thrust for forward flight. Some helicopters have more than one rotor and a few have rotors turned by gas jets at the tips.
Autogyros have unpowered rotors, with a separate power plant to provide thrust. The rotor is tilted backward. As the autogyro moves forward, air blows upward across the rotor, making it spin. This spinning increases the speed of airflow over the rotor, to provide lift. Rotor kites are unpowered autogyros, which are towed to give them forward speed or tethered to a static anchor in high-wind for kited flight.
Other methods of lift:

A lifting body is an aircraft body shaped to produce lift. If there are any wings, they are too small to provide significant lift and are used only for stability and control. Lifting bodies are not efficient: they suffer from high drag, and must also travel at high speed to generate enough lift to fly. Many of the research prototypes, such as the Martin Marietta X-24, which led up to the Space Shuttle, were lifting bodies, though the Space Shuttle is not, and some supersonic missiles obtain lift from the airflow over a tubular body.
Powered lift types rely on engine-derived lift for vertical takeoff and landing (VTOL). Most types transition to fixed-wing lift for horizontal flight. Classes of powered lift types include VTOL jet aircraft (such as the Harrier Jump Jet) and tiltrotors, such as the Bell Boeing V-22 Osprey, among others.
Size :
The smallest aircraft are toys/recreational items, and nano aircraft.
The largest aircraft by dimensions and volume (as of 2016) is the 302 ft (92 m) long British Airlander 10, a hybrid blimp, with helicopter and fixed-wing features, and reportedly capable of speeds up to 90 mph (140 km/h; 78 kn), and an airborne endurance of two weeks with a payload of up to 22,050 lb (10,000 kg).
The largest aircraft by weight and largest regular fixed-wing aircraft ever built, as of 2016, is the Antonov An-225 Mriya. That Ukrainian-built six-engine Russian transport of the 1980s is 84 m (276 ft) long, with an 88 m (289 ft) wingspan. It holds the world payload record, after transporting 428,834 lb (194,516 kg) of goods, and has recently flown 100 t (220,000 lb) loads commercially. With a maximum loaded weight of 550–700 t (1,210,000–1,540,000 lb), it is also the heaviest aircraft built to date. It can cruise at 500 mph (800 km/h; 430 kn).
The largest military airplanes are the Ukrainian Antonov An-124 Ruslan (world’s second-largest airplane, also used as a civilian transport), and American Lockheed C-5 Galaxy transport, weighing, loaded, over 380 t (840,000 lb). The 8-engine, piston/propeller Hughes H-4 Hercules “Spruce Goose” an American World War II wooden flying boat transport with a greater wingspan (94m/260ft) than any current aircraft and a tail height equal to the tallest (Airbus A380-800 at 24.1m/78ft) — flew only one short hop in the late 1940s and never flew out of ground effect.
The largest civilian airplanes, apart from the above-noted An-225 and An-124, are the Airbus Beluga cargo transport derivative of the Airbus A300 jet airliner, the Boeing Dreamlifter cargo transport derivative of the Boeing 747 jet airliner/transport (the 747-200B was, at its creation in the 1960s, the heaviest aircraft ever built, with a maximum weight of over 400 t (880,000 lb)),and the double-decker Airbus A380 “super-jumbo” jet airliner
Size and speed extremes:
Speeds :
The fastest recorded powered aircraft flight and fastest recorded aircraft flight of an air-breathing powered aircraft was of the NASA X-43A Pegasus, a scramjet-powered, hypersonic, lifting body experimental research aircraft, at Mach 9.6, exactly 3,292.8 m/s (11,854 km/h; 6,400.7 kn; 7,366 mph). The X-43A set that new mark, and broke its own world record of Mach 6.3, exactly 2,160.9 m/s (7,779 km/h; 4,200.5 kn; 4,834 mph), set in March 2004, on its third and final flight on 16 November 2004.
Prior to the X-43A, the fastest recorded powered airplane flight (and still the record for the fastest manned, powered airplane / fastest manned, non-spacecraft aircraft) was of the North American X-15A-2, rocket-powered airplane at Mach 6.72, or 2,304.96 m/s (8,297.9 km/h; 4,480.48 kn; 5,156.0 mph), on 3 October 1967. On one flight it reached an altitude of 354,300 ft (108,000 m).
The fastest known, production aircraft (other than rockets and missiles) currently or formerly operational (as of 2016) are:
The fastest fixed-wing aircraft, and fastest glider, is the Space Shuttle, a rocket-glider hybrid, which has re-entered the atmosphere as a fixed-wing glider at more than Mach 25, equal to 8,575 m/s (30,870 km/h; 16,668 kn; 19,180 mph).
The fastest military airplane ever built: Lockheed SR-71 Blackbird, a U.S. reconnaissance jet fixed-wing aircraft, known to fly beyond Mach 3.3, equal to 1,131.9 m/s (4,075 km/h; 2,200.2 kn; 2,532 mph). On 28 July 1976, an SR-71 set the record for the fastest and highest-flying operational aircraft with an absolute speed record of 2,193 mph (3,529 km/h; 1,906 kn; 980 m/s) and an absolute altitude record of 85,068 ft (25,929 m).
Uses for aircraft:
Aircraft are produced in several different types optimized for various uses; military aircraft, which includes not just combat types but many types of supporting aircraft, and civil aircraft, which include all non-military types, experimental and model.
Military:

A military aircraft is any aircraft that is operated by a legal or insurrectionary armed service of any type.] Military aircraft can be either combat or non-combat:
Combat aircraft are aircraft designed to destroy enemy equipment using its own armament.Combat aircraft divide broadly into fighters and bombers, with several in-between types, such as fighter-bombers and attack aircraft, including attack helicopters.
Non-combat aircraft are not designed for combat as their primary function, but may carry weapons for self-defense. Non-combat roles include search and rescue, reconnaissance, observation, transport, training, and aerial refueling. These aircraft are often variants of civil aircraft.
Civil:

Civil aircraft divide into commercial and general types, however there are some overlaps.
Commercial aircraft include types designed for scheduled and charter airline flights, carrying passengers, mail and other cargo. The larger passenger-carrying types are the airliners, the largest of which are wide-body aircraft. Some of the smaller types are also used in general aviation, and some of the larger types are used as VIP aircraft.
General aviation is a catch-all covering other kinds of private (where the pilot is not paid for time or expenses) and commercial use, and involving a wide range of aircraft types such as business jets (bizjets), trainers, homebuilt, gliders, warbirds and hot air balloons to name a few. The vast majority of aircraft today are general aviation types.
Model:
A model aircraft is a small unmanned type made to fly for fun, for static display, for aerodynamic research or for other purposes. A scale model is a replica of some larger design.
The end…
A technical skills screening tool is software that contains a rich library of technical assessment tests, including questions and answers for recruiters to screen and evaluate candidates.
The assessments created on these platforms are used to evaluate candidates before employment by technical recruiters and/or hiring managers.
Skill assessments are not the only type of evaluation used by the hiring teams – job simulation resumes, and reference checks are all common screening methods. The trouble with resumes and reference checks is that they don’t reveal the whole picture. A candidate and often their references will attempt to present the applicant in the best positive light. Unfortunately, this may not be the most accurate portrayal of the candidate’s skills and abilities.

Job simulations, also known as work simulations, require candidates to perform tasks that the role requires in the workplace. These simulations are an effective evaluation tactic to understand how the candidate will perform in the real work environment.
Structured interviews are also an effective evaluation method, and they include a scoring system similar to that of skill assessments. The common denominator between the two methods is that they are both quantitative and can thus be reliably compared and contrasted. Moreover, recruiters can extract useful insights from the collected data.
Screen developers at scale with accurate, custom programming tests that evaluate technical skills hyper-relevant to the role.
Skill assessments have the added benefit of providing recruiters with the opportunity to reliably screen out candidates pre-interview. Thus, when it comes to tech hiring, skill tests take the cake to justify reliability, efficiency, and cost-effectiveness.
While skill tests are great, we mentioned earlier that you need the right kind of assessment to guarantee fair evaluation and the best results. Therefore, the ideal technical screening tool should offer:
Of course, not every tool will have all these features. So let’s take a look at the best technical screening tools for tech recruiters and hiring managers and see which one wins out.
WeCreateProblems has the largest repository of technical interview questions & tests. Where other platforms average a few thousand to generously over 10,000 questions, WeCP has over 0.2 million+ technical questions in the bank. The question bank contains skill test questions for every tech role, whether it’s frontend or full-stack development, data science, DevOps, or something else.
Tech recruiters can generate custom tests on-demand with WeCP to evaluate over 2000 different technical skills. Need morecustomization with the test questions and design? WeCP’s team is on standby to help you out there too.
Aside from the impressive size of the question bank and the high quality of the questions themselves, WeCP sets itself apart from the competition in another big way – the evaluation process. WeCP uses SkillMaps for scientifically evaluating candidates, guaranteeing accuracy, and all the tests in the repository have been thoroughly vetted. Moreover, WeCP’s technical screening is made cheat-proof through:
WeCP’s questions are thoroughly scrutinized for difficulty, guaranteeing candidates can’t just Google the answers or prepare for them beforehand. Whether you design a custom test or use a pre-built one, WeCP guarantees unique, challenging, skill-mapped assessments to help you track down the best candidate.
Codility is a powerful tech screening solution and remote hiring tool tailored for engineering teams. The recruitment platform has been around since 2009 and provides employers with powerful screening and interviewing tools.
Codility has a diverse knowledge base and includes skill tests for various roles – you can use the tool to evaluate potential candidates for frontend and backend developer positions, data science, language skills, and more. However, one drawback of using this tool is that it lacks AI-powered video proctoring and web proctoring features, which may lead to cheating.
One of Codility’s most appreciated features is its ‘candidate feedback’ option. If you enable this feature, Codility provides candidates with a breakdown of their score immediately after submission of the skill test. Enabling automated candidate feedback helps recruiters be more transparent about the hiring process.
CodeSignal is a popular technical screening tool for tech recruiters with a decent repository of questions, web proctoring, on-demand custom questions, and even video interviews.
CodeSignal is a relatively young recruitment platform, having popped up in 2015, but it has since made a good name for itself. The tool helps recruiters generate custom tests for a wide variety of programming languages and developer skills.
Pedigree is a poor proxy for programming skills. Broaden your candidate pool and qualify individuals based on their coding skills. Measuring developer skills accurately and at scale is easy with CodeSignal.
Some candidates have expressed concern regarding CodeSignal’s existing questions, citing them to be verbose and difficult to comprehend. On the whole, though, CodeSignal is a reliable tool. It has helped many tech companies evolve past using resumes for evaluation into the more reliable realm of coding skill tests.
HackerRank is a popular developer screening tool. The platform offers assessment tests for a variety of skills, including tests for full-stack development skills and database skills.
From simple coding challenges to full-stack engineering scenarios, allow developers to demonstrate their design, development, and communication skills in a real-time pair programming environment, complete with a virtual whiteboard. Add projects that provide insight into the quality of work candidates will perform at your company.
HackerRank has been around since 2012 and has since grown its client list to over 2000. The tool provides framework support and helps recruiters assess up to 44 skills with its rich repository of questions. After designing your custom assessment with HackerRank, you can opt for the automated scoring system or manually score the tests.
HackerEarth has the makings of a solid technical screening tool – it has a decent question bank (sporting over 15000 questions), has tests for all relevant skills, and has features like video interviews that some of its competitors lack.

The field of electronics is a branch of physics and electrical engineering that deals with the emission, behaviour and effects of electrons using electronic devices. Electronics uses active devices to control electron flow by amplification and rectification, which distinguishes it from classical electrical engineering, which only uses passive effects such as resistance, capacitance and inductance to control electric current flow.

Electronics has hugely influenced the development of modern society. The identification of the electron in 1897, along with the subsequent invention of the vacuum tube which could amplify and rectify small electrical signals, inaugurated the field of electronics and the electron age.Practical applications started with the invention of the diode by Ambrose Fleming and the triode by Lee De Forest in the early 1900s, which made the detection of small electrical voltages such as radio signals from an radio antenna possible with a non-mechanical device. The growth of electronics was rapid, and by the early 1920s commercial radio broadcasting and communications were becoming widespread, and electronic amplifiers were being used in such diverse applications as long distance telephony and the music recording industry.
The next big technological step took several decades to appear, when Solid-state electronics emerged with the first working semiconductor transistor which was invented by William Shockley, Walter Houser Brattain and John Bardeen in 1947. The vacuum tube was no longer the only means of controlling electron flow. The MOSFET (MOS transistor) was subsequently invented in 1959, and was the first compact transistor that could be miniaturised and mass-produced. This played a key role in the emergence of microelectronics and the Digital Revolution. Today, electronic devices are universally used in Computers, telecommunications and signal processing employing Integrated circuits with sometimes millions of transistors on a single chip.
Electronic devices and components:

An electronic component is any physical entity in an electronic system used to affect the electrons or their associated fields in a manner consistent with the intended function of the electronic system. Components are generally intended to be connected together, usually by being soldered to a printed circuit board (PCB), to create an electronic circuit with a particular function (for example an amplifier, radio receiver, or oscillator). Components may be packaged singly, or in more complex groups as integrated circuits. Some common electronic components are capacitors, inductors, resistors, diodes, transistors, etc. Components are often categorized as active (e.g. transistors and thyristors) or passive (e.g. resistors, diodes, inductors and capacitors).

History of electronic components :

Vacuum tubes (Thermionic valves) were among the earliest electronic components. They were almost solely responsible for the electronics revolution of the first half of the twentieth century. They allowed for vastly more complicated systems and gave us radio, television, phonographs, radar, long-distance telephony and much more. They played a leading role in the field of microwave and high power transmission as well as television receivers until the middle of the 1980s. Since that time, solid-state devices have all but completely taken over. Vacuum tubes are still used in some specialist applications such as high power RF amplifiers, cathode ray tubes, specialist audio equipment, guitar amplifiers and some microwave devices.
The first working point-contact transistor was invented by John Bardeen and Walter Houser Brattain at Bell Labs in 1947. In April 1955, the IBM 608 was the first IBM product to use transistor circuits without any vacuum tubes and is believed to be the first all-transistorized calculator to be manufactured for the commercial market. The 608 contained more than 3,000 germanium transistors. Thomas J. Watson Jr. ordered all future IBM products to use transistors in their design. From that time on transistors were almost exclusively used for computer logic and peripherals. However, early junction transistors were relatively bulky devices that were difficult to manufacture on a mass-production basis, which limited them to a number of specialised applications.
Types of circuits:
Circuits and components can be divided into two groups: analog and digital. A particular device may consist of circuitry that has one or the other or a mix of the two types. An important electronic technique in both analog and digital electronics involves the use of feedback. Among many other things this allows very linear amplifiers to be made with high gain, and digital circuits such as registers, computers and oscillators.
Analog circuits:

Most analog electronic appliances, such as radio receivers, are constructed from combinations of a few types of basic circuits. Analog circuits use a continuous range of voltage or current as opposed to discrete levels as in digital circuits.

The number of different analog circuits so far devised is huge, especially because a ‘circuit’ can be defined as anything from a single component, to systems containing thousands of components.
Analog circuits are sometimes called linear circuits although many non-linear effects are used in analog circuits such as mixers, modulators, etc. Good examples of analog circuits include vacuum tube and transistor amplifiers, operational amplifiers and oscillators.
Digital circuits:

Digital circuits are electric circuits based on a number of discrete voltage levels. Digital circuits are the most common physical representation of Boolean algebra, and are the basis of all digital computers. To most engineers, the terms “digital circuit”, “digital system” and “logic” are interchangeable in the context of digital circuits. Most digital circuits use a binary system with two voltage levels labeled “0” and “1“. Often logic “0” will be a lower voltage and referred to as “Low” while logic “1” is referred to as “High“. However, some systems use the reverse definition (“0” is “High”) or are current based. Quite often the logic designer may reverse these definitions from one circuit to the next as he sees fit to facilitate his design. The definition of the levels as “0” or “1” is arbitrary.

Electronics theory :
Mathematical methods are integral to the study of electronics. To become proficient in electronics it is also necessary to become proficient in the mathematics of circuit analysis.
Circuit analysis is the study of methods of solving generally linear systems for unknown variables such as the voltage at a certain node or the current through a certain branch of a network. A common analytical tool for this is the SPICE circuit simulator.
Also important to electronics is the study and understanding of electromagnetic field theory.
Electronics lab:

Due to the complex nature of electronics theory, laboratory experimentation is an important part of the development of electronic devices. These experiments are used to test or verify the engineer’s design and detect errors. Historically, electronics labs have consisted of electronics devices and equipment located in a physical space, although in more recent years the trend has been towards electronics lab simulation software, such as CircuitLogix, Multisim, and PSpice.
Electronic systems design:

Electronic systems design deals with the multi-disciplinary design issues of complex electronic devices and systems, such as mobile phones and computers. The subject covers a broad spectrum, from the design and development of an electronic system (new product development) to assuring its proper function, service life and disposal. Electronic systems design is therefore the process of defining and developing complex electronic devices to satisfy specified requirements of the user.
Electronics industry :

The electronics industry consists of various sectors. The central driving force behind the entire electronics industry is the semiconductor industry sector, which has annual sales of over $481 billion as of 2018. The largest industry sector is e-commerce, which generated over $29 trillion in 2017. The most widely manufactured electronic device is the metal-oxide-semiconductor field-effect transistor (MOSFET), with an estimated 13 sextillion MOSFETs having been manufactured between 1960 and 2018. In the 1960s, U.S. manufacturers were unable to compete with Japanese companies such as Sony and Hitachi who could produce high-quality goods at lower prices. By the 1980s, however, U.S. manufacturers became the world leaders in semiconductor development and assembly.

Social media are interactive technologies that facilitate the creation and sharing of information, ideas, interests, and other forms of expression through virtual communities and networks. While challenges to the definition of social media arise due to the variety of stand-alone and built-in social media services currently available, there are some common features:
* Social media are interactive Web 2.0 Internet-based applications.
* User-generated content such as text posts or comments, digital photos or videos, and data generated through all online interactions is the lifeblood of social media.
* Users create service-specific profiles for the website or app that are designed and maintained by the social media organization.
* Social media helps the development of online social networks by connecting a user’s profile with those of other individuals or groups

Users usually access social media services through web-based apps on desktops or download services that offer social media functionality to their mobile devices (e.g., smartphones and tablets). As users engage with these electronic services, they create highly interactive platforms which individuals, communities, and organizations can share, co-create, discuss, participate, and modify user-generated or self-curated content posted online. Additionally, social media are used to document memories; learn about and explore things; advertise oneself; and form friendships along with the growth of ideas from the creation of blogs, podcasts, videos, and gaming sites.This changing relationship between humans and technology is the focus of the emerging field of technological self-studies.Some of the most popular social media websites, with more than 100 million registered users, include Facebook (and its associated Facebook Messenger), TikTok, WeChat, Instagram, QZone, Weibo, Twitter, Tumblr, Baidu Tieba, and LinkedIn. Depending on interpretation, other popular platforms that are sometimes referred to as social media services include YouTube, QQ, Quora, Telegram, WhatsApp, Signal, LINE, Snapchat, Pinterest, Viber, Reddit, Discord, VK, Microsoft Teams, and more. Wikis are examples of collaborative content creation.
Many social media outlets differ from traditional media (e.g., print magazines and newspapers, TV, and radio broadcasting) in many ways, including quality,reach, frequency, usability, relevancy, and permanence. Additionally, social media outlets operate in a dialogic transmission system, i.e., many sources to many receivers, while traditional media outlets operate under a monologic transmission model (i.e., one source to many receivers). For instance, a newspaper is delivered to many subscribers and a radio station broadcasts the same programs to an entire city.
Since the dramatic expansion of the Internet, digital media or digital rhetoric can be used to represent or identify a culture. Studying how the rhetoric that exists in the digital environment has become a crucial new process for many scholars.
Observers have noted a wide range of positive and negative impacts when it comes to the use of social media. Social media can help to improve an individual’s sense of connectedness with real or online communities and can be an effective communication (or marketing) tool for corporations, entrepreneurs, non-profit organizations, advocacy groups, political parties, and governments. Observers have also seen that there has been a rise in social movements using social media as a tool for communicating and organizing in times of political unrest.
History of social media :
Early computing:

The PLATO system was launched in 1960, after being developed at the University of Illinois and subsequently commercially marketed by Control Data Corporation. It offered early forms of social media features with 1973-era innovations such as Notes, PLATO’s message-forum application; TERM-talk, its instant-messaging feature; Talkomatic, perhaps the first online chat room; News Report, a crowdsourced online newspaper, and blog; and Access Lists, enabling the owner of a note file or other application to limit access to a certain set of users, for example, only friends, classmates, or co-workers.
ARPANET, which first came online in 1967, had by the late-1970s developed a rich cultural exchange of non-government/business ideas and communication, as evidenced by the network etiquette (or ‘netiquette’) described in a 1982 handbook on computing at MIT’s Artificial Intelligence Laboratory.ARPANET evolved into the Internet following the publication of the first Transmission Control Protocol (TCP) specification, RFC 675 (Specification of Internet Transmission Control Program), written by Vint Cerf, Yogen Dalal and Carl Sunshine in 1974. This became the foundation of Usenet, conceived by Tom Truscott and Jim Ellis in 1979 at the University of North Carolina at Chapel Hill and Duke University, and established in 1980.
A precursor of the electronic bulletin board system (BBS), known as Community Memory, appeared by 1973. True electronic BBSs arrived with the Computer Bulletin Board System in Chicago, which first came online on February 16, 1978. Before long, most major cities had more than one BBS running on TRS-80, Apple II, Atari, IBM PC, Commodore 64, Sinclair, and similar personal computers. The IBM PC was introduced in 1981, and subsequent models of both Mac computers and PCs were used throughout the 1980s. Multiple modems, followed by specialized telecommunication hardware, allowed many users to be online simultaneously. Compuserve, Prodigy and AOL were three of the largest BBS companies and were the first to migrate to the Internet in the 1990s. Between the mid-1980s and the mid-1990s, BBSes numbered in the tens of thousands in North America alone. Message forums (a specific structure of social media) arose with the BBS phenomenon throughout the 1980s and early 1990s. When the World Wide Web (WWW, or ‘the web’) was added to the Internet in the mid-1990s, message forums migrated to the web, becoming Internet forums, primarily due to cheaper per-person access as well as the ability to handle far more people simultaneously than telco modem banks.
Digital imaging and semiconductor image sensor technology facilitated the development and rise of social media. Advances in metal-oxide-semiconductor (MOS) semiconductor device fabrication, reaching smaller micron and then sub-micron levels during the 1980s–1990s, led to the development of the NMOS (n-type MOS) active-pixel sensor (APS) at Olympus in 1985, and then the complementary MOS (CMOS) active-pixel sensor (CMOS sensor) at NASA’s Jet Propulsion Laboratory (JPL) in 1993.CMOS sensors enabled the mass proliferation of digital cameras and camera phones, which bolstered the rise of social media.
Social impacts
Disparity
The digital divide is a measure of disparity in the level of access to technology between households, socioeconomic levels or other demographic categories.People who are homeless, living in poverty, elderly people and those living in rural or remote communities may have little or no access to computers and the Internet; in contrast, middle class and upper-class people in urban areas have very high rates of computer and Internet access. Other models argue that within a modern information society, some individuals produce Internet content while others only consume it, which could be a result of disparities in the education system where only some teachers integrate technology into the classroom and teach critical thinking. While social media has differences among age groups, a 2010 study in the United States found no racial divide. Some zero-rating programs offer subsidized data access to certain websites on low-cost plans. Critics say that this is an anti-competitive program that undermines net neutrality and creates a “walled garden”for platforms like Facebook Zero. A 2015 study found that 65% of Nigerians, 61% of Indonesians, and 58% of Indians agree with the statement that “Facebook is the Internet” compared with only 5% in the US.
Political polarization:
According to the Pew Research Center, a majority of Americans at least occasionally receive news from social media. Because of algorithms on social media which filter and display news content which are likely to match their users’ political preferences, a potential impact of receiving news from social media includes an increase in political polarization due to selective exposure. Political polarization refers to when an individual’s stance on a topic is more likely to be strictly defined by their identification with a specific political party or ideology than on other factors. Selective exposure occurs when an individual favors information that supports their beliefs and avoids information that conflicts with their beliefs. A study by Hayat and Samuel-Azran conducted during the 2016 U.S. presidential election observed an “echo chamber” effect of selective exposure among 27,811 Twitter users following the content of cable news shows.The Twitter users observed in the study were found to have little interaction with users and content whose beliefs were different from their own, possibly heightening polarization effects. Another study using U.S. elections, conducted by Evans and Clark, revealed gender differences in the political use of Twitter between candidates.Whilst politics is a male dominated arena, on social media the situation appears to be the opposite, with women discussing policy issues at a higher rate than their male counter-parts. The study concluded that an increase in female candidates directly correlates to an increase in the amount of attention paid to policy issues, potentially heightening political polarization.
Stereotyping :
Recent research has demonstrated that social media, and media in general, have the power to increase the scope of stereotypes not only in children but people of all ages.Three researchers at Blanquerna University, Spain, examined how adolescents interact with social media and specifically Facebook. They suggest that interactions on the website encourage representing oneself in the traditional gender constructs, which helps maintain gender stereotypes. The authors noted that girls generally show more emotion in their posts and more frequently change their profile pictures, which according to some psychologists can lead to self-objectification. On the other hand, the researchers found that boys prefer to portray themselves as strong, independent, and powerful. For example, men often post pictures of objects and not themselves, and rarely change their profile pictures; using the pages more for entertainment and pragmatic reasons. In contrast, girls generally post more images that include themselves, friends and things they have emotional ties to, which the researchers attributed that to the higher emotional intelligence of girls at a younger age. The authors sampled over 632 girls and boys from the ages of 12–16 from Spain in an effort to confirm their beliefs. The researchers concluded that masculinity is more commonly associated with positive psychological well-being, while femininity displays less psychological well-being. Furthermore, the researchers discovered that people tend not to completely conform to either stereotype, and encompass desirable parts of both. Users of Facebook generally use their profiles to reflect that they are a “normal” person. Social media was found to uphold gender stereotypes both feminine and masculine. The researchers also noted that traditional stereotypes are often upheld by boys more so than girls. The authors described how neither stereotype was entirely positive, but most people viewed masculine values as more positive.
Effects on youth communication:
Social media has allowed for mass cultural exchange and intercultural communication. As different cultures have different value systems, cultural themes, grammar, and world views, they also communicate differently.The emergence of social media platforms fused together different cultures and their communication methods, blending together various cultural thinking patterns and expression styles
Social media has affected the way youth communicate, by introducing new forms of language. Abbreviations have been introduced to cut down on the time it takes to respond online. The commonly known “LOL” has become globally recognized as the abbreviation for “laugh out loud” thanks to social media.
Social media has offered a new platform for peer pressure with both positive and negative communication. From Facebook comments to likes on Instagram, how the youth communicate, and what is socially acceptable is now heavily based on social media.Social media does make kids and young adults more susceptible to peer pressure. The American Academy of Pediatrics has also shown that bullying, the making of non-inclusive friend groups, and sexual experimentation have increased situations related to cyberbullying, issues with privacy, and the act of sending sexual images or messages to someone’s mobile device. On the other hand, social media also benefits the youth and how they communicate. Adolescents can learn basic social and technical skills that are essential in society. Through the use of social media, kids and young adults are able to strengthen relationships by keeping in touch with friends and family, make more friends, and participate in community engagement activities and services.
Deceased users:
Social media content, like most content on the web, will continue to persist unless the user deletes it. This brings up the inevitable question of what to do once a social media user dies, and no longer has access to their content.As it is a topic that is often left undiscussed, it is important to note that each social media platform, e.g., Twitter, Facebook, Instagram, LinkedIn, and Pinterest, has created its own guidelines for users who have died.In most cases on social media, the platforms require a next-of-kin to prove that the user is deceased, and then give them the option of closing the account or maintaining it in a ‘legacy’ status. Ultimately, social media users should make decisions about what happens to their social media accounts before they pass, and make sure their instructions are passed on to their next-of-kin
The end….
Time, a word consists of only four alphabets but still holds the biggest impact in life. Time is like a flow of river which is irreversible in any case. Once it’s gone, YOU’VE COMPLETELY LOST IT. Still, we let lots of our time go in vain on the daily basis. Of course, there are humans who never learn until and unless they get a hard punishment for it or they go through regrets. From study to relationships, everything has its right time to be completed on.
Even so humans waste their time in thinking how their time is wasted. It’s ridiculous. Isn’t it? They regret why they wasted their time when they could have done something better with it. Only foolish people think that time is free or granted to them. Once this thought gets stuck in their mind, then their life is OVER which will be filled with emptiness.
What to do now when you are in a phase where you don’t know even where your time is going ?
In simple words, you just wake up and do the things which are required to do at the spot and then just go to sleep. NO goals and NO satisfaction. What is the solution now?
You must be wondering what kind of leakage I am talking about! I am referring to the leakage of time. Analyse your whole day and find out where your most of the time is leaking or wasting when at that period you are not even doing some productive work. Once you find out then cut that time and restrict yourselves to do that activity gradually day by day. You can not cut down an activity (unproductive) which you have been doing for a long time immediately. You will get to know that your half of the day is spent on doing insignificant things which are not gonna help you in long run.
Now when you know in which activities your time is being leaked, try to stop them one by one. You can’t control your mind immediately. To avoid distractions, you have to stop looking at them like distraction. For example, watching Netflix is a distraction and a leakage for you. You had decided to watch a particular series for one hour and ended up watching it completely for the whole day and these things had been repeating day by day. Believe me, in a blink of eye, your whole month will be wasted on it as on Netflix many series are going to come everyday. You need the resolution and strong determination to reduce your leakage of time gradually. Invest your time in doing something productive which is going to be helpful in your life.
After allocating your time to do productive activities, you need to decide daily short goals and accomplish them. The satisfaction you will get everyday after completing the goals would be immeasurable.
This is your life whether you make it meaningful or meaningless, this all depends on you. Some use their time meticulously to become the top leaders in the world while other give mediocre efforts to live an average life. You only get one life. Why not give your best to live the life of your dreams ? Just decide for yourself what you want to do and then work tirelessly to achieve the top results with the utmost efforts!
Are you aware of Dukan diet ? Easy way to reduce your weight.
Dukan Diet is intaking rich protein and low carbohydrate food in order to get rid from obesity and lose weight by breaking diet into four phases. Dr.Pierre Dukan who created the dukan diet in 1970 was a French Physician,Nutritionist and Specialized in weight management. Dukan created this diet to meet the needs of his patients.After getting successful result from this diet,he published the book ” The Dukan Diet ” in 2000. The Dukan Diet attained world- wide popularity. And the book released in 32 countries ,translated into more than 14 languages.
Consult with your doctor
A person must consult with his doctor before taking the dukan diet whether his body condition is appropriate for the diet. And should start the diet with proper planning and continuing with the advise of best dietist. One should ready for the diet both mentally and physically.
Intake of pure protein food is the primary step in the attack phase with 1.5 tablespoon of oat bran for fibre content and minimal calories. And you can take unlimited quantities of pure protein. You have to drink 7-9 cups of water daily. Regular physical activities and exercise for 20 mins per day helps mostly. These phase helps for instant weight loss. The duration for attack phase depends on the weight of the person.
What To Consume
68 pure proteins

32 Vegetables : Egg plant, okra, onions, mushrooms, carrot, broccoli,Watercress, turnip, tomato, pumpkin, bean sprouts, cucumber, leeks, shallots,Zucchini, artichoke, asparagus.
What To Avoid
Fruits
Starchy vegetables like potatoes and corn
Fats
Alcohol
3.Consolidation Phase (1-5 days)
It helps to prevent from regaining the weight. In this phase,the person can take unlimited foods under 100 items without any restrictions and also allowed to take a glass of wine , desert as a celebration meals each week. You can take oat bran of 2.5 tablespoon. You can add some carbohydrates during this consolidation fees and also 25 minutes of exercise.
What To Consume
Wholegrain bread, Fruit, Cheese,Entree, A glass of wine .
What To Avoid
Banana,Grapes,Figs,Sugar,Cherries.
4.Sabilization Phase
The final phase allows to eat carbohydrates more than other 3 phases. But 1 day in a week should take complete lean protein. You can take 3 tablespoon of oat bran. During this phase try to use stairs instead of an elevator. And take a brisk walk for 20 minutes.
Disadvantages Of Dukan Diet
1) Intake of less carbohydrates leads to bad breath, nausea, weakness and headaches.
2) People become so tired during the attack phase. So Dr. Dukan advises people to avoid lift heavy weights.
3) Less consumption of carbohydrates can lead to constipation.
4) It may leads to nutritional deficiency because of lack of whole grains,fruits.
5) Nutritional deficiency may leads to various problems such as cancer and heart attack to premature aging.
6) Pure protein intake may cause kidney problems and bone related diseases.
Advantages Of Dukan Diet
1) Instant weight loss makes people feel good.
3) It is possible to reduce weight without heavy workout.
4) Calorie-counting is not involved.
The Dukan diet has both pros and cons equally. So,people with blood pressure, sugar complaints and with other diseases practicing this diet is highly risky and may cause serious health issue.

The Indian Navy Day will be observed on December 4 every year to recognize their sacrifices, efforts and achievements. At forth India was first celebrate it’s Navy day at 21st October 1944. After World War II(1945) it was celebrated on December 1 later it was celebrated on 4th December. During the Navy week celebrations lot of performance will be inaugurated such as open sea swimming competition, ships are open for visitors and school children, there is an veteran sailors launch. Symphonic Orchestra take place and an Indian Navy Inter school competitions, Navy-half marathon also happens. Indian Navy Day is about commemorate Operation Trident (attack on Karachi harbor during Indo-Pakistan war).
Indian Navy was established by East Indian Company in 1612. This year (2021) Navy plans to celebrate in the theme of swarnim Vijay varsh to celebrate 50th anniversary of India’s victory in the 1971 war. Our Prime Minister of India Narendra Modi who twitts “we are proud of exemplary contributions of the Indian Navy. Our Navy is widely respected for it’s professionalism and outstanding courage. Our navy personnel have always been at the forefront of mitigating crisis situation like natural disasters”, he says. Indian Air Forces also extended it’s warm wishes and greetings to all personnel and families of @indiannavy on the occasion of 43rd Navy day.
Every year they propose different theme last year theme was “Indian Navy Combat Ready”. This year is ‘Swarnim Vijay Varsh’ which significe 50 years of India’s victory in the Indo-Pakistan war that took place in 1971. There are some quotes which represents Indian Navy 2021, “We are safe because we have our Navy protecting us each and every moment. Salute to our Navy and best wishes on Indian Navy Day”. “Let us celebrate Indian Navy Day by saluting all the women and men in the Navy for their bravery, dedication and patriotism “. It goes like….
The story begins around the time of 17th century when Dutch East India Company employed hundreds of ships to make the trade of various products like gold, porcelain, spices and silks around the globe. Trading of these things required a lot of money with good business plans. Things being not cheap, company came up with a wonderful idea. In order to have money for their expensive voyages, company started to target the private citizens. They targeted those group of people who could invest in their business.
In exchange, they agreed to share a certain part of the profit from their business with them. This practice allowed them to make large amount of profits not only for themselves but also for their investors. Selling their shares in various kind of places, Dutch East India Company unknowingly invented the world’s first Stock Market. With their first step towards the stock market, till now the company has been collecting the large amount of money in form of shares to support their different businesses.
Stock basically refers to the part of ownership of investors in one or several companies. Modern Stock Market is definitely more complicated than the prior one.
How do companies and investors use stock market nowadays?
When a company decides to launch in a market, then it first proposes its central or main idea in front of the big investors. If the investors like the company’s plan and ideas then they offer their sponsorship to it which is called Initial Public Offering (IPO).
Afterwards, company advertise itself in the official public market where any company or the individual who thinks the plan can be profitable starts to invest in the stocks of the company. Investing in the stocks make the investors partial owners in the business. With increment in the growth of the company, more investors see the potential of it and start to invest in the company.
With increase in the demands of the stocks, the price of them also increases which further raises the value of the stocks that people already own. This also increases the market value of the company. If the company seems to be less profitable in future then the demand of its stocks also decline leading to a loss for the investors if they not sell their stocks prior to when their value declines.
These situations occur due to unavoidable circumstances of market forces i.e. demand and supply. Demand and supply are totally dependent upon people’s preferences and contentment. Some other factors which also influence these situations are change in production technology, shifting costs of labor and fluctuating price of materials etc. It is highly unpredictable to get success in each and every investment due to the changing of circumstances. That’s why, various experts are building different tools to predict high chance of success in investment. With the help of internet, now in each and every part of the world, there are people from rich to poor who are ready to dive in the sea of investment. While earning income, it has become a duty to invest some money in stocks in order to pursue long-term financial goals.
Social media plays vital role in present society.It become one of the daily necessary activity.Social media is typically used for social interaction and access to news and information, and decision making. It is a valuable communication tool with locally and worldwide, as well as to share, create, and spread information.Social media enables its users to stay in contact by making communication easier. Sharing pictures, videos, expressing thoughts, ideas, and documents are just one click away. Exchanging messages and data from one corner of world to other is made easiest with the help of social media.The term social media refers to a computer-based technology that facilitates the sharing of ideas, thoughts, and information through virtual networks and communities. Social media is internet-based and gives users quick electronic communication of content, such as personal information, documents, videos, and photos.

The negative effects of mass media on society can lead people towards poverty, crime, nudity, violence, bad mental and physical health disorders and others as such severe outcomes. For example mob hitting innocents by getting carried away from the rumors spread on the internet has been common.Social media, or more specifically news media- plays an important role in democratic societies because they allow for participation among citizens.when it comes to healthy democratic networks, it is crucial that that news remains true so it doesn’t affect citizens levels of trust.Eighty-six percent (86%) of people use social media at least once per day, including 72% who use it multiple times per day. Social media is so popular because it allows people to manage and accomplish their everyday activities. Social media is a great way to connect with people who you may not see all the time. It’s also great for making friends. Social media helps you build connections with kids who have the same interests. It is a quick way for people to get to know each other, even if they’re living across the world from one another.
“Don’t use social media to impress people use it to impact people”.
Why freedom of press is important? A fundamental need for a democratic society is free press. Freedom of speech is a universal human right. Without fundamental right India would just be another one of the countries like Syria, North Korea and cretain African countries, where there is still dictatorship and one party rule. Jawaharlal Nehru said “I would rather have a completely free press, with all dangers involved in the wrong use of that freedom,than the suppressed or regulated press.” In union of India vs association for democratic reforms the supreme court observed that freedom of speech and expression includes right to impart and receive information which includes freedom to hold opinion. Freedom of press has three essesntial elements.
1. Freedom of access to all sources information
2. Freedom of publication
3. Freedom of circulation.
The constitution of India gives us the ability to express what we want to say. This is called freddom of speech and expression.But it doesn’t really mean that what we can say or do whatever we want.Freedom of press is not specifically mentioned in article 19(1)(a). However it was made clear by the drafting committee that the press and an individual or a citizen were the same as far as their expression was concerned. In fact the constitution of India enforces a few terms and conditions that come along with this called “reasonable retrictions” This is expressed in article(19)(2) which lists eight restrictions that limits this freedom.
1. SECURITY OF THE STATE
Speeches which insite or encourage the commission of violent crimes comes under threat to the security of state. Eg: for rebellion, war against the state, breaches of pubic safety etc
2. FRIENDLY RELATIONS WITH FOREIGN STATE
To prohibit unrestrained malicious propaganda against a friendly state which could jeopardize the good relations between the two states.
3. PUBLIC ORDER
Implies absence of violence and an orderly state of affairs in which citizens can peacefully pursue their normal avocation of life. Thus creating internal disorder or rebellion would affect public order. Law punishing utterences made with the deliberate intention to hurt the relegious feelings of any class of person is valid because it imposes a restriction on the right of free speech in the interest of public order. Since such kind of speech or writing has the tendency to create public disorder
4. DECENCY OR MORALITY
Sections 292 and 294 of Indian penal code provides instances of restrictions on the freedom of speech amd expression in the interest of decency or morality. These sections prohibit the sale or distribution or exhibition of obscene words etc in public places.
5. CONTEMPT OF COURT
Restriction on the freedom of speech and expression can be imposed if it exceeds the reasonable and fair limit and amounts to contempt of court.
6. DEFAMATION
A statement which injures a man’s reputation, amounts to defamation. Defamation consists in exposing a man to hatred, ridicule or contempt.
7. INCITEMENT TO AN OFFENCE
Freedom of speeech and expression cannot confer a right to incite people to commit offences.
8. SOVEREIGNTY AND INTEGRITY OF STATE
The main purpose is to guard the freedom of speech and expression from being used to assail the sovereignty and integrity of the state.
A free press has a huge responsibility of reporting the truth and shaping people’s opinions. Responsible Journalism must be practiced to stop people from spreading hate and maintaining the harmony of a country.
Can you imagine this, what will happen, if you don’t know the things happening around you? And what’s going on in your region? It can be anything like a weather report, government policies, crimes etc. You will be isolated and outdated. There comes journalism for your aid. Journalism helps us to know what’s happening around us, it gives us information about everything going on in earth and even in the outer space. Without it, our life don’t operate properly. On considering journalism, there are enormous things to be covered. But now our concern is on fashion and lifestyle journalism.

Fashion journalism concentrate on the current trends and styles. It comprise of writing related to fashion trends and photojournalism which plays major role in this field. There are lot of people who love to dress up or to act accordingly to the current trends, fashion journalism is for them. It helps us to know the designs or styles which is on trend today, keep us updated day to day and educate people about the fashion shows, events and new trends.
Let’s look at the job of fashion journalists and what they are doing in this field. Fashion journalists write and edit articles related to fashion. They conduct interviews with the celebrities and fashion icons as celebrities rule the world of fashion, nowadays all the people want to look like a celebrity, so they try to impersonate celebrities by knowing the secret of their fashion from these interviews. Other than this, fashion journalists cover the fashion shows and events and research about the upcoming trends. They have to work along with photographers, designers and fashion specialists. Like any other journalists, fashion journalists should have good communication skills to conduct interviews and should have the pre acquired knowledge of fashion and trends.
Magazines are the main outcome of fashion journalism. There are enormous fashion magazine like Vogue, Elle, Cosmopolitan, Femina. Most of them got it’s digital portal as it is needed for today’s world. Apart from these magazines, YouTube became the next fashion promoting platform, it have these particular Youtubers who propagate the current trends and fashion in their videos.
Fashion is the part of life but not the life itself. Fashion and lifestyle journalism is similar but lifestyle journalism covers lot more than fashion. Lifestyle journalism concentrate on travel, fashion, food, well-being, health, fitness etc. The target of lifestyle journalism is consumers, so they give contents according to the needs of customers and also directed to audience of it’s own. Lifestyle journalism consists of the bloggers who write blogs about certain products or on topics which are in trend now.
Fashion and lifestyle journalism comes under soft journalism. The term soft journalism means the type of journalism which don’t affect the society directly and it is not the subject of human interest. Fashion and lifestyle is soft journalism because it don’t affect the public in general as not everyone is interested in fashion and it won’t disturb them in anyway like a crime news or a government policy which have greater effect in their life. It may not be the mainstream, but fashion and lifestyle journalism have it’s own audience who made it evolved this greatly.
Crypto means hidden or secret. So, literally cryptocurrency is the (private digital) currency which is concealed. To put it in simple words, this currency does not exist physically but digitally in secret. When someone trades using cryptocurrency then the transaction is being registered through public ledger. Some of the famous examples of the cryptocurrency are Bitcoin, Ripple, Dogecoin and Ethereum etc. With passing of time, the popularity of cryptocurrency has risen up.
How does Cryptocurrency work?
The ledger where the transactions through this currency happens is being maintained by a lot of computers with the help of a lot of people which is popularly known as Peer to Peer Network. These transactions are being recorded as the blocks. With increment of each transaction, new blocks keep adding up to create a chain which is called as Blockchain. No one can disturb this order of Blockchain with any kind of fraud as it is present in a network of computers with full transparency. It is easy to track any kind of trickery with such a high level of transparency.
The software or computers which carry out these transactions are called Miners and the process through which these transactions is being carried out is called Mining.
As the transactions are registered on public ledger, so to maintain the privacy of the money that one person have, all the money and transactions are being coded which is called as cryptography.
The idea of making currency decentralised gave birth to cryptocurrency. So that everyone can try out their luck to have more and more money. But to handle the situation of how much money in this currency should be produced, the prices are being fixed prior to any trade. So, the price of any currency would be determined according to its supply and demand.
What are the advantages of Cryptocurrency?
What are the disadvantages of Cryptocurrency?
In India, it has not been recognised as the legal tender of the money. So, people can’t use cryptocurrency fully here. But investment in cryptocurrency is legal in India. Nonetheless, what new changes cryptocurrency will bring into this world are yet to be seen..

Even though the Internet is still a young technology, it’s hard to imagine life without it now. Every year, engineers create more devices to integrate with the Internet. This network of networks crisscrosses the globe and even extends into space. But what makes it work?
To understand the Internet, it helps to look at it as a system with two main components. The first of those components is hardware. That includes everything from the cables that carry terabits of information every second to the computer sitting in front of you.
Other types of hardware that support the Internet include routers, servers, cell phone towers, satellites, radios, smartphones and other devices. All these devices together create the network of networks. The Internet is a malleable system — it changes in little ways as elements join and leave networks around the world. Some of those elements may stay fairly static and make up the backbone of the Internet. Others are more peripheral.
These elements are connections. Some are end points the computer, smartphone or other device you’re using to read this may count as one. We call those end points clients. Machines that store the information we seek on the Internet are servers. Other elements are nodes which serve as a connecting point along a route of traffic. And then there are the transmission lines which can be physical, as in the case of cables and fiber optics, or they can be wireless signals from satellites, cell phone or 4G towers, or radios.
All of this hardware wouldn’t create a network without the second component of the Internet: the protocols. Protocols are sets of rules that machines follow to complete tasks. Without a common set of protocols that all machines connected to the Internet must follow, communication between devices couldn’t happen. The various machines would be unable to understand one another or even send information in a meaningful way. The protocols provide both the method and a common language for machines to use to transmit data.
A Matter of Protocols:

You’ve probably heard of several protocols on the Internet. For example, hypertext transfer protocol is what we use to view Web sites through a browser that’s what the http at the front of any Web address stands for. If you’ve ever used an FTP server, you relied on the file transfer protocol. Protocols like these and dozens more create the framework within which all devices must operate to be part of the Internet.
Two of the most important protocols are the transmission control protocol (TCP) and the Internet protocol (IP). We often group the two together — in most discussions about Internet protocols you’ll see them listed as TCP/IP.
What do these protocols do? At their most basic level, these protocols establish the rules for how information passes through the Internet. Without these rules, you would need direct connections to other computers to access the information they hold. You’d also need both your computer and the target computer to understand a common language.
You’ve probably heard of IP addresses. These addresses follow the Internet protocol. Each device connected to the Internet has an IP address. This is how one machine can find another through the massive network.
The version of IP most of us use today is IPv4, which is based on a 32-bit address system. There’s one big problem with this system: We’re running out of addresses. That’s why the Internet Engineering Task Force (IETF) decided back in 1991 that it was necessary to develop a new version of IP to create enough addresses to meet demand. The result was IPv6, a 128-bit address system. That’s enough addresses to accommodate the rising demand for Internet access for the foreseeable future [source: Opus One].

When you want to send a message or retrieve information from another computer, the TCP/IP protocols are what make the transmission possible. Your request goes out over the network, hitting domain name servers (DNS) along the way to find the target server. The DNS points the request in the right direction. Once the target server receives the request, it can send a response back to your computer. The data might travel a completely different path to get back to you. This flexible approach to data transfer is part of what makes the Internet such a powerful tool.
Packet, Packet, Who’s Got the Packet?
What is the Internet?

The internet is composed of computer networks that allow users to access information from other computers (provided that they have permission to do so). The internet often uses various protocols such as TCP/IP to make this communication possible.
What are the main features of the internet?

One of the main features of the internet is accessibility. Anyone with access to a computer and a broadband connection can gain access to the internet without restriction. The internet also happens to be low cost and compatible with most platforms.
How does data move through the Internet?

Data is chopped into packets. These packets move through an ISP. The ISP routes the request to a server further up the chain on the internet. Eventually, the request will hit a domain name server (DNS). This server will look for a match for the domain name you’ve typed in (such as http://www.howstuffworks.com). If it finds a match, it will direct your request to the proper server’s IP address. Packets have headers and footers that tell computers what’s in the packet and how the information fits with other packets to create an entire file. Each packet travels back up the network and down to your computer.
How much data is on the internet?

Studies by PwC found that the internet had reached about 4.4 ZB (zettabytes) of data by 2019. (A zettabyte is 1,073,741,824 terabytes.) Most of this data is held by service companies like Amazon, Microsoft, Facebook, and Google.

Everyone makes mistakes in life, we are believed to learn from our mistakes or try to avoid them, same happens when building a niche website, mistakes can cause damage to your brand value or prevent you get disire results.
However, no one really talks much about how doing things wrong on your website can deteriorate your image and cost you your business. There are common mistakes that are often made not out of ignorance but coincidentally or because of forgetfulness.
Effects of these mistakes can be seen in sales, website visitation rates, and bounce rates. This is why you need to be aware of them and have tools and knowledge to improve your website, eliminate the mistakes you are making, and inevitably, improve your business.
To avoid certain things which are causing us to gain the maximum number of reach I want you to keep these ‘10 Disappointing Niche Website Mistakes You Make Now’ in your mind while building a website.
“A successful website does three things:
It attracts the right kinds of visitors.
Guides them to the main services or products you offer.
Collect Contact details for future ongoing relations.”
― Mohamed Saad
The most successful component of a growing website is single, original quality content, which will increase your credibility and authority in your chosen area. It will also increase your search engine ranking.
Evergreen content would be something like an article that teaches you how to tie a bowtie. Something like that isn’t time-sensitive, so you can essentially write it once and continue driving traffic to it forever.
For example: if you own a photography studio you must add your best high-res photos or video to your website which attracts the customer which will direct them to buy your services.
| Indicators | Checklist |
| Timely | Up-to-date information |
| How frequently the website is updated | |
| When the website was updated | |
| Relevant | Organization’s objectives |
| Organization’s history | |
| Customers (audience) | |
| Products or services | |
| Photography of organization’s facilities | |
| Multilanguage/culture | Use different languages |
| Present to different cultured | |
| Variety of presentation | Different forms (text, audio, video, …) |

The point is marketing on Social Media is rapidly becoming an excellent way to drive traffic to your website. Likely to soon be second only to Organic traffic as one of the more economical means of attracting visitors.
Google looks for keywords on your website and Google will send visitors to your website based on the keywords they find there.
There are various websites you can follow like niche affiliate, niche academy a super affiliate, etc. they are all here to train you, build up your skills, and make your website more attractive and interesting. Some of them are paid courses and some will train you for free. I would recommend you can start with the free course then go for the paid version for a better understanding and advanced learning.
Unfortunately, many Newcomers treat this more like a “hobby”, than a business. You will be never able to figure that out. It can be used to get a little better organized yourself. You must have ‘hunger’ enough to take the advice of some very successful people and treat my business, as a business.
A blog is an aspect of operations that many websites outsource, and if you’re incapable of producing an interesting blog, then you should certainly consider farming the task out to a professional writer. A good writer will be able to create engaging headlines and titles, with an article that is written utilizing SEO, and yet is still personable and promotional (but not too promotional – a blog is different from an advertorial). You may hire a content writer online at a price. Prices vary from their experience in the field.
Not mentioning or forgetting to mention NAP (Name, Address, Telephone number) or not keeping it up updated will cost you to lose your customer forever. Your NAP needs to be clearly displayed and updated as needed, they can be directed to an incorrect location, or are unable to contact you via a method of their choosing.
Conclusion
Starting a niche website is easy. Getting it set up on WordPress and writing your first article is simple stuff that anybody can do. The difficult part comes in growing it into a money-making niche site. As you learned in this guide, there are a lot of moving parts. It takes patience, hard work, and persistence.
The biggest reason for failure is simply that people give up too quickly. And it’s not their fault. If it’s your first time, you don’t know what to expect. You don’t know the processes and different cycles that a new niche website goes through before breaking through and finally being successful.
Niche websites can truly change your life if you want them to. Starting a successful website can open a lot of different doors for you. It can allow you to quit your job, finally, travel the world, or just get some really good side income money.

What exactly is Starlink?
It is a satellite-based global internet system that SpaceX has been building for years to bring internet access to underserved areas of the world. The idea is to beam high-speed, low-latency broadband internet to remote areas.

Starlink is a satellite internet constellation operated by SpaceX providing satellite Internet access to most of the Earth. The constellation consists of over 1600 satellites in mid-2021, and will eventually consist of many thousands of mass-produced small satellites in low Earth orbit (LEO), which communicate with designated ground transceivers. While the technical possibility of satellite internet service covers most of the global population, actual service can be delivered only in countries that have licensed SpaceX to provide service within any specific national jurisdiction. As of November 2021, the beta service offering is available in 20 countries.
How many satellites are part of this constellation?

According to a recent Bloomberg report, SpaceX’s Starlink unit has deployed more than 1,700 satellites to date in low-earth orbit. This number could eventually reach 30,000 if it receives the necessary regulatory approvals and market demand warrants.
How does it work?

There are no ground-based internet cables at play here. These satellites beam information through space. It travels 47% faster than fibre optics cable, according to Space.com. On the ground, these signals are received through a dish, which is also connected to a WiFi router.
The SpaceX satellite development facility in Redmond, Washington houses the Starlink research, development, manufacturing, and orbit control teams. The cost of the decade-long project to design, build, and deploy the constellation was estimated by SpaceX in May 2018 to be at least US$10 billion.
Early-stage planning began in 2014, with product development occurring in earnest by 2017. Two prototype test-flight satellites were launched in February 2018. Additional test satellites and 60 operational satellites were deployed in May 2019. SpaceX launches up to 60 satellites at a time, aiming to deploy 1,584 of the 260 kg (570 lb) spacecraft to provide near-global service by late 2021 or 2022.

On 15 October 2019, the United States Federal Communications Commission (FCC) submitted filings to the International Telecommunication Union (ITU) on SpaceX’s behalf to arrange spectrum for 30,000 additional Starlink satellites to supplement the 12,000 Starlink satellites already approved by the FCC.By 2021, SpaceX had entered into agreements with Google Cloud Platform and Microsoft Azure to provide on-ground compute and networking services for Starlink.
Astronomers have raised concerns about the constellations’ effect on ground-based astronomy and how the satellites will add to an already jammed orbital environment. SpaceX has attempted to mitigate these concerns by implementing several upgrades to Starlink satellites aimed at reducing their brightness during operation. The satellites are equipped with krypton-fueled Hall thrusters which allow them to de-orbit at the end of their life. Additionally, the satellites are designed to autonomously avoid collisions based on uplinked tracking data.

Each satellite in the Starlink project weighs just 573 pounds (260kg). The body of each satellite is flat, and up to 60 of them can fit into one of SpaceX’s Falcon 9 rockets. Once put in orbit, a single large solar array comes out to power the satellite. The central portion includes four powerful antennas for internet transmissions. Each satellite relies on a set of lasers to connect with four others in orbit. Finally, they have ion thrusters that use krypton gas. This allows them to stay in orbit longer, even at these lower distances from Earth.
How many satellites have launched so far?

SpaceX launched its first test satellites in 2018. This was followed by the first official 60 satellites for the service in 2019. The most recent launch took place in mid-November 2021, with further launches planned for each month of the year. As of this writing, SpaceX has put up about 1,844 satellites into orbit. It’s well beyond the initial projection of 1,440 satellites, and that number means that SpaceX has completed its first “shell” of satellites.
How much will Starlink internet access cost? In a CNN article, an email reportedly from Starlink is inviting people to try out the service. The email claims that it will cost $499 for a one-time cost for the ground hardware and $99 a month for the basic internet service. Starlink has recently developed a new dish that is smaller and lighter than before, named Dishy McFlatface. However, it still costs $499.
By comparison, the HughesNet service costs as much as $150 a month, with a 50GB high-speed data plan (at 25Mbps) and horrible latency that makes gaming impossible, and even tasks like streaming can be quite the chore.

The end….
After the fast-spreading of Omicron variant of COVID-19 in the various parts of the world, a new terror has been emerged in the people of the country. So far, two positive cases of Omicron* variant have been detected in Karnataka.
To reduce the spreading of this variant in different parts of the country, the Health Ministry of the country has been advising the states and union territories to strictly check upon the international passengers who have been coming from ‘at risk’ countries.
International passengers coming from ‘at risk’ countries are advised to go for RT-PCR* test. Only after the reports of their tests are available, they are allowed to step out from the airport. This situation created a lot of chaos in Kempegowda International Airport in Bengaluru on Wednesday, December 1. Long queues were witnessed at the airport due to the guidelines regarding the mandatory RT-PCR test of the international passengers at the airport passed down by Union Health Ministry.
Only four doctors and 25 staffers were deployed at the airport according to the reports. Moreover, there was only one testing counter located for screening the passengers. A lot of passengers showed their discomforts during the testing through various social media handles.
Among those passengers, Raja Andukondan was also the one who faced issues while testing. He raised his complaints through his Twitter handle.
He stated, “@BLRAirport As one of the passengers on the very first flight which landed after 00:00hrs, it was horrible. Clearly the lab Auriga Research was not at all prepared. Who can I contact for a refund of my cost for the Rapid PCR test? Results were promised in 1 hr but took 3+ hrs”.
According to the current guidelines, passengers coming from ‘at risk’ countries have to go through post-arrival testing and will be isolated in case the reports turn out to be positive.
Due to the fast-spreading of Omicron variant of COVID-19, all the residents of India are advised to ensure their safety and not to take it lightly in any case. It is to be hoped that all the people will be able to overcome this crisis very soon with their own vigilance.
*Omicron variant –
It is a new variant of COVID-19 that has been kicked-off in South Africa. A sudden surge of positive cases broke out among the university students. At first, scientists mistook this omicron variant in the students as delta variant. But after the research, the omicron variant was found out with a lot of mutations which stirred up a chaos among the scientists. On 24 November, this variant was reported to World Health Organisation. According to WHO, this variant poses a ‘very high risk’. Following different reports, it is to be said that this variant could be the most contagious one to be ever known in the history.
*RT-PCR test-
Reverse Transcription Polymerase Chain Reaction (RT-PCR) is the test where an enzyme called reverse transcriptase used to change the piece of RNA into a same matching piece of DNA. This method is used to detect the specific genetic material in any pathogen. It is one of the widely used methods to detect the COVID-19 virus in a diseased body.
Sir Chandrasekhara Venkata Raman FRS was an Indian physicist known for his work in the field of light scattering. Using a spectrograph that he developed, he and his student K. S. Krishnan discovered that when light traverses a transparent material, the deflected light changes its wavelength and frequency.He was born in 7th November 1888 in Thiruvanaikoil, Tiruchirappalli His parents was R. Chandrasekhar Iyer, Parvathi Ammal.He did his education in st Aloysius Anglo Indian High school, presidency College.

C.V.Raman Theory proposed a theory that when light that shines through a material is scattered and its wavelength changes from that of the original incident light because of its interactions with the molecules in the material.This is also called as Raman effect.C.V. Raman is also known as Chandrashekhara Venkata Raman. He was a man of brilliant mind who has done his matriculation at the age of 11 and 12th class at the age of 13. Let us solve an interesting quiz on Dr. C.V. Raman which throws light on his life and inventions done by him.07-Nov-2019
He received many awards,
* 1928-Matteucci medal.
* 1930-Hughes medal.
* 1930-Nobel prize in physics.
* 1941-Franklin medal.
* 1954-Bhart ratna.
* 1957-Lenin peace prize.
A communications satellite is an artificial satellite that relays and amplifies radio telecommunication signals via a transponder; it creates a communication channel between a source transmitter and a receiver at different locations on Earth’s. Communications satellites are used for television, telephone, radio, internet, and military applications. As of 1 January 2021, there are 2,224 communications satellites in Earth orbit. Most communications satellites are in geostationary orbit 22,300 miles (35,900 km) above the equator, so that the satellite appears stationary at the same point in the sky; therefore the satellite dish antennas of ground stations can be aimed permanently at that spot and do not have to move to track the satellite.

The high frequency radio waves used for telecommunications links travel by line of sight and so are obstructed by the curve of the Earth. The purpose of communications satellites is to relay the signal around the curve of the Earth allowing communication between widely separated geographical points. Communications satellites use a wide range of radio and microwave frequencies. To avoid signal interference, international organizations have regulations for which frequency ranges or “bands” certain organizations are allowed to use. This allocation of bands minimizes the risk of signal interference.
In October 1945, Arthur C. Clarke published an article titled “Extraterrestrial Relays” in the British magazine Wireless World.The article described the fundamentals behind the deployment of artificial satellites in geostationary orbits for the purpose of relaying radio signals. Because of this, Arthur C. Clarke is often quoted as being the inventor of the concept of the communications satellite, and the term ‘Clarke Belt’ is employed as a description of the orbit.

The first artificial Earth satellite was Sputnik 1 which was put into orbit by the Soviet Union on October 4, 1957. It was developed by Mikhail Tikhonravov and Sergey Korolev, building on work by Konstantin Tsiolkovsky.Sputnik 1 was equipped with an on-board radio-transmitter that worked on two frequencies of 20.005 and 40.002 MHz, or 7 and 15 meters wavelength. The satellite was not placed in orbit for the purpose of sending data from one point on earth to another; the radio transmitter was meant to study the properties of radio wave distribution throughout the ionosphere. The launch of Sputnik 1 was a major step in the exploration of space and rocket development, and marks the beginning of the Space Age.
Satellite orbits :

Communications satellites usually have one of three primary types of orbit, while other orbital classifications are used to further specify orbital details. MEO and LEO are non-geostationary orbit (NGSO).
Geostationary satellites have a geostationary orbit (GEO), which is 22,236 miles (35,785 km) from Earth’s surface. This orbit has the special characteristic that the apparent position of the satellite in the sky when viewed by a ground observer does not change, the satellite appears to “stand still” in the sky. This is because the satellite’s orbital period is the same as the rotation rate of the Earth. The advantage of this orbit is that ground antennas do not have to track the satellite across the sky, they can be fixed to point at the location in the sky the satellite appears.
Medium Earth orbit (MEO) satellites are closer to Earth. Orbital altitudes range from 2,000 to 36,000 kilometres (1,200 to 22,400 mi) above Earth.
The region below medium orbits is referred to as low Earth orbit (LEO), and is about 160 to 2,000 kilometres (99 to 1,243 mi) above Earth.
As satellites in MEO and LEO orbit the Earth faster, they do not remain visible in the sky to a fixed point on Earth continually like a geostationary satellite, but appear to a ground observer to cross the sky and “set” when they go behind the Earth beyond the visible horizon. Therefore, to provide continuous communications capability with these lower orbits requires a larger number of satellites, so that one of these satellites will always be visible in the sky for transmission of communication signals. However, due to their relatively small distance to the Earth their signals are stronger.
Low Earth orbit (LEO)

A low Earth orbit (LEO) typically is a circular orbit about 160 to 2,000 kilometres (99 to 1,243 mi) above the earth’s surface and, correspondingly, a period (time to revolve around the earth) of about 90 minutes.
Because of their low altitude, these satellites are only visible from within a radius of roughly 1,000 kilometres (620 mi) from the sub-satellite point. In addition, satellites in low earth orbit change their position relative to the ground position quickly. So even for local applications, many satellites are needed if the mission requires uninterrupted connectivity.
Low-Earth-orbiting satellites are less expensive to launch into orbit than geostationary satellites and, due to proximity to the ground, do not require as high signal strength (signal strength falls off as the square of the distance from the source, so the effect is considerable). Thus there is a trade off between the number of satellites and their cost.
In addition, there are important differences in the onboard and ground equipment needed to support the two types of missions.
Satellite constellation:

A group of satellites working in concert is known as a satellite constellation. Two such constellations, intended to provide satellite phone services, primarily to remote areas, are the Iridium and Globalstar systems. The Iridium system has 66 satellites.
It is also possible to offer discontinuous coverage using a low-Earth-orbit satellite capable of storing data received while passing over one part of Earth and transmitting it later while passing over another part. This will be the case with the CASCADE system of Canada’s CASSIOPE communications satellite. Another system using this store and forward method is Orbcomm.
Medium Earth orbit (MEO):

A medium Earth orbit is a satellite in orbit somewhere between 2,000 and 35,786 kilometres (1,243 and 22,236 mi) above the earth’s surface. MEO satellites are similar to LEO satellites in functionality. MEO satellites are visible for much longer periods of time than LEO satellites, usually between 2 and 8 hours. MEO satellites have a larger coverage area than LEO satellites. A MEO satellite’s longer duration of visibility and wider footprint means fewer satellites are needed in a MEO network than a LEO network. One disadvantage is that a MEO satellite’s distance gives it a longer time delay and weaker signal than a LEO satellite, although these limitations are not as severe as those of a GEO satellite.
Like LEOs, these satellites do not maintain a stationary distance from the earth. This is in contrast to the geostationary orbit, where satellites are always 35,786 kilometres (22,236 mi) from the earth.
Typically the orbit of a medium earth orbit satellite is about 16,000 kilometres (10,000 mi) above earth. In various patterns, these satellites make the trip around earth in anywhere from 2 to 8 hours.

No one remains a stranger to this phrase, But there is nothing more vague and inarticulate than this phrase. From the moment we are born into this world, we are being directed to behave and do things in a certain way. When we reach adolescence, we no longer have to be told to behave in a certain way as we begin to realise what the society expects from us and behave in accordance to their expectations. Finally, when we enter adulthood, we become champions in complying to societal expectations.
After going through all these stages in life, while in a group discussion or a meeting, a team leader or a manager asks us to think outside the box. That’s unfair. Nobody taught us to think for ourselves, even if we did, it fell in the societal pattern of studying, marrying, rearing kids, and retiring.
In a professional terminology, thinking out of the box basically means coming up with a new idea (because the contemporary ones didn’t work) that would reap huge benefits for the company. In terms of life, thinking out of the box means being indifferent to societal norms and expectations as you do things your own way. Although my monologue above is defensive towards societal expectations, it is often impractical as not all of us can afford to waste our time and resources on carving a new path, when we can comply with our society and become financially stable and independent.
Nevertheless, we can still incorporate the habit of thinking outside the box to make a difference in our lives when needed. Thinking out of the box does not require racking your brains till you come up with a feasible idea.
Enrolling yourself for a new course will open doors to learning about new and unfamiliar things. Learning new things will influence your thinking in different areas and aspects of your life. Thereafter when you are confronted with a problem, you will be equipped with knowledge from the specialisation in a certain field that can aid you with thinking out of the box.
Although it sounds counter intuitive, daydreaming is an important factor that influences your thinking out of the box. While daydreaming, your brain is led astray from the logical aspects and helps you make connections and co-relations that you couldn’t come up with while racking your brain. So, turn your attention away from the problem you are facing and let your imagination go wild!
Thinking out of the box would require you to do things differently or try new things. So how about reading from a different genre than the one you usually prefer? Try nonfiction or didactical if you have always preferred fiction. Fiction might have accustomed you to think in a certain manner. To break that monotony in thinking, reading from a different genre might just do the trick.
The motive behind doing this relatively weird stuff during a serious confrontation is to break free from rational and logical thinking and invite new possibilities and ideas into the situation. Try writing a poem on the basis of your problems. As your mind begins wandering to support your efforts in poetry, you expand your horizon of thinking, leading to thinking outside the box.
So there you go, a vague article on an equally vague topic. Thinking out of the box. Do drop in your thoughts in the comment box. Now that’s a rhyme scheme created which can be considered as the first two lines of a poem. I was wondering how to end this article so I made a rhyme scheme, a.k.a a poem.
This blog post introduces the importance of online education for students in countries where there has been a widespread outbreak of the H1N1 virus, such as India and Pakistan. It discusses how to prepare for an upcoming event, such as Covid-19, by accessing resources over the net. It also suggests that educational institutes should offer short term course courses such as weeks or months so that learners can access uninterrupted learning material. The blog post also mentions improving connectivity in remote areas and installing internet cafes so that learners can access quality resources at their convenience.
“If you are an industry executive, manager, supervisor, administrator etc. working in the field of education you will be able to improve your work performance by one or two notches if you fall in the category of ‘active learners’. While talking about learning there is a need to combine different kinds of sources like classrooms, labs, labs online and also online courses. “Active learners” are those who are always keen to learn new things and are aware of the latest developments being done in their field. The present world today runs on a ‘knowledge economy, where knowledge base has become the most important source of success and failure, so it is only for you to take different steps to improve your career and also grab the assured positions”
We all know that learning is a continuous process and it requires constant effort. A learner should have a positive attitude towards learning and should be committed to it. The mode of knowledge transfer has changed seriously, so if you want to compete today in the field of education and gain success then focus on online courses and engage yourself in online activities regularly. If you really want to gain success and become a leader then take steps that will help you to be an active learner.
Many people, including the youth, don’t know how to use technology for their benefit. Some parents do not support their children’s education as they don’t know what is online education and they think it’s harmful to their kids as they spend more time on the internet. Well-organized mind, be regular in his work, stay motivated, help friends with their learning problems etc. only then he can achieve positive results. Each one of us should try to be an active learner to prosper in life. “Learning is not just sitting in the class sitting through lectures or books” If you are feeling hard to learn anything then just do it. become very powerful tools for making money. These tools should be utilized properly so that much more wealth could be created for our nation.
