Definition: system administrator

A person who manages the computer systems in an organization. The responsibilities of a system administrator and network administrator often overlap; however, the system administrator is more geared to the computer hardware and less on the network, although in many cases, system and network administrator are one in the same, especially in smaller companies. A system administrator is involved with OS and hardware installations and configurations and may be involved with application installations and upgrades. A system administrator may also perform systems programmer activities.
