Network and computer systems administrators design, install, and support an organization’s computer systems. They are responsible for local area networks (LANs), wide area networks (WANs), network segments, and Internet and intranet systems. They work in a variety of environments, including large corporations, small businesses, and government organizations. They install and maintain network hardware and software, analyze problems, and monitor networks to ensure their availability to users. These workers gather data to evaluate a system’s performance, identify user needs, and determine system and network requirements.

Systems administrators are responsible for maintaining system efficiency. They ensure that the design of an organization’s computer system allows all of the components, including computers, the network, and software, to work properly together. Administrators also troubleshoot problems reported by users and by automated network monitoring systems and make recommendations for future system upgrades. Many of these workers are also responsible for maintaining network and system security.

Companies generally require their network and computer systems administrators to be certified in the products they use. Certification programs usually are offered directly from vendors or from vendor-neutral certification providers. Certification validates the knowledge and the use of best practices that are required of network and computer systems administrators. Microsoft and Cisco offer some of the most common certifications.
