Network and Computer Systems Administrators

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.

What do Network and computer systems administrators do?

  • Determine what the organization needs in a network and computer system before it is set up
  • Install all network hardware and software and make needed upgrades and repairs
  • Maintain network and computer system security and ensure that all systems are operating correctly
  • Collect data in order to evaluate the network’s or system’s performance and help make the system work better and faster
  • Add users to a network and assign and update security permissions on the network
  • Train users on the proper use of hardware and software
  • Solve problems when a user or an automated monitoring system informs them that a problem exists

Administrators manage an organization’s servers and desktop and mobile equipment. 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.



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