Description : A network administrator oversees computer networks to ensure that they function smoothly. A network consists of a grouping of computers that communicate with each other or a central computer known as a server, on which computer files, programs, and other information are stored. A network may be as small as two or three computers or as large as the Internet, the world's largest computer network.
Whereas a network technician or engineer designs and sets up the infrastructure for a computer network, a network administrator usually configures and manages an existing network. He or she may be responsible for customizing the network to an individual company's needs by connecting the necessary hardware and software to the network. Once the network is configured, the administrator adds computer programs, such as e-mail, that the company's employees use on a daily basis. A network administrator's work usually depends on the size of the network for which he or she is responsible. The smaller the network, the more duties a network administrator handles. For large networks, several individuals may perform different tasks related to the network. The administrator then monitors the performance of the network and troubleshoots any problems such as slow performance or network crashes. A crash occurs when users cannot access the network or use all of its features properly. The administrator must also work with individual users who are having network problems that are not experienced by other users.
Some network problems may result in the loss or corruption of data stored on the server. For this reason, the administrator must develop, install, and maintain emergency systems to back up the main network server. Administrators keep records of all users' problems and errors as well as the steps taken to solve the problems. This information is used to help solve future problems.
Administrators also control user access to the network. This includes setting up passwords for individual users and determining which files, programs, or features each person is allowed to use. The administrator must also create a firewall—a set of security measures designed to make sure that no one can gain unauthorized access to the system. In larger firms this task may fall to a network security specialist. Network security also involves monitoring the network to see who is using it and how. A security specialist is responsible for changing passwords periodically and updating security measures and procedures.
