All about Networking

Network Engineers design, develop, install, test, and maintain networks that link computers, peripherals (fax machines, printers, modems), communication equipment (telephones, cellular phones), and video equipment (cameras, VCRs) using cabling methods of wireless transmissions and software.

Sharing is the basic reason that networks exist. Through networks, the greatest number of users can access applications, hardware, and information and thereby, attain cost-saving, efficiency, and widened communication.

Ask ten different people what networking is and you may get as many as ten different answers. A person’s definition of networking probably depends upon their use of this important personal and professional activity. However, whether your network is to make new friends, find a new job, develop your current career, explore new career options, obtain referrals or sales leads, or simply broaden your professional horizons, it is important to focus on networking as an exchange of information, contacts or experience.

Computer networks enable communication for every business, entertainment, and research purpose. The internet, online search, email, audio and video sharing, online commerce, live-streaming, and social networks all exist because of computer networks.


Although a 4-year degree in Engineering is the routine educational preparation, it is becoming increasingly necessary for certain certification of network-related competency. Several network hardware and software vendors after certification programs that at least an individual’s basic network knowledge or specialized knowledge of that company’s products.

There are three to four companies well known for their educational courses. Microsoft offers several courses for a network engineer link Microsoft Certified Professional, Microsoft Certified Professional Internet, Microsoft Certified Systems Engineer, Microsoft Certified Systems Engineer Internet, or Microsoft Solution Developer.The most highly regarded of them all is CISCO systems.

It offers a course containing three levels, the lowest level of certification is Cisco Certified Network Associate, secondly Cisco Certificate Network Professional, and ultimately, Cisco Certified Interwork Expert Certification.
