What Network and Computer Systems Administrators Do

Computer networks are critical parts of almost every organization. Network and computer systems administrators are responsible for the day-to-day operation of these networks. They organize, install, and support an organization’s computer systems, including local area networks (LANs), wide area networks (WANs), network segments, intranets, and other data communication systems.


Network and computer systems administrators typically do the following:

Administrators manage an organization’s servers. They ensure that email and data storage networks work properly. They also make sure that employees’ workstations are working efficiently and stay connected to the central computer network. Some administrators manage telecommunication networks at their organization.

In some cases, administrators help network architects who design and analyze network models. They also participate in decisions about buying future hardware or software to upgrade the organization’s network. Some administrators provide technical support to computer users, and they may supervise computer support specialists who help users with computer problems.
