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.
Duties
Network and computer systems administrators typically do the following:
Determine an organization's network and computer system needs before setting one 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 and optimize network or system performance
Add users to a network and assign and update security permissions on the network
Train users in the proper use of hardware and software
Interpret and solve problems when a user or an automated monitoring system alerts them that one 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.
