What is a systems administrator?
The role that installs, configures, and maintains an organization's networks, servers, and systems — the O*NET definition.
What it means
O*NET describes Network and Computer Systems Administrators as professionals who "install, configure, and maintain an organization's local area network (LAN), wide area network (WAN), data communications network, operating systems, and physical and virtual servers."
It is a common mid-level destination from entry IT support, and credentials like CompTIA Network+/Server+, Linux certifications, and Cisco CCNA often map to it.
