System Administrator

"*** A system administrator (SA) is responsible for managing, overseeing and maintaining a multiuser computing environment, such as a local area network (LAN). ***

SA responsibilities vary, depending on an organization's requirements. SAs should possess strong technical knowledge and skills, as well as expertise in personnel management.

A SA is also known as a systems administrator, sys admin or sysadmin. A small organization may have only one SA on staff, while an enterprise usually has a full SA team.

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:

Determine an organization’s system needs and install network hardware and software, Make needed upgrades and repairs to networks and ensure that systems are operating correctly, Maintain network and computer system security, 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 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.

Administrators may 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.
