Computer networking is the science of entwining computers in a way that data can be exchanged between the computers. In other words computer networking is the communication between computer systems or devices. It could be using LAN or Local Area Network, which is curbed to a small area like interconnected computers in an office. Networking can also be of WAN type, which is a large network covering a large geographic area. And computer networking can be wireless LANs and WANs (WLAN & WWAN), which is the wireless comparable of the LAN and WAN in which all networks are interconnected to allow communication with a varsity of different kinds of media, like Bluetooth and internet.
Computer networking jobs are highly specified and viable jobs that require sufficient training. In almost all organizations these days, network connectivity is mandatory for smooth functioning of all departments.
Network engineers have a very important role to play in establishing and maintaining this capability at corporations, hospitals and universities. Responsibilities in computer networking jobs include building, maintaining and administering computer networks. The role greatly varies from industry to industry, however it broadly includes troubleshooting of hardware and software, providing network support and performing system design and analysis. Obviously, network engineers often work in high-pressure environment and are required to keep their cool and must stay up-to-date on the latest technologies. Qualification requirements include a bachelor’s degree, certifications and several years of experience working on a help desk or as a system administrator
Computer network management and maintenance is another very important aspect, which includes maintenance of network facilities in individual machines, such as drivers and settings of personal computers.
It also includes maintenance of network servers. Outsourcing provides access to highly skilled people without the expense of maintaining a large in-house staff, offering services such as computer help, reliable network management, network maintenance help and support, data backup support and much more.
With the growth of the Internet and the expansion of the World Wide Web a variety of occupations related to the design, development, and maintenance of web sites and their servers have come up. Since networks are configured in many ways, network systems and data communications analysts are needed to design, test, and evaluate systems such as local area networks, wide area networks, the Internet, Intranets and other data communications systems. Employment of network engineers and administrators is expected to increase faster than the average for all other occupations through 2014. Computer networking job growth will continue to grow and is rightly projected to remain one of the fastest-growing industries in the U.S. economy.
