Computer systems administrators set up and maintain an organization’s computer servers. In a single day, they may encounter stacks of servers, dozens of crisscrossing network cables and major malfunctions with the hardware and software that runs the company’s local area and wide area networks.

A network and computer systems administrator’s greatest contribution is maintaining an organization’s work flow and keeping its lines of communication open. This work is not for the faint of heart. Since companies depend on their networks for so much of their work, problems must be corrected swiftly and completely. Aside from identifying network issues and fixing them, computer systems administrators must also make updates to all equipment and software so they’re current.

Another important aspect of the job is ensuring email and data storage networks work properly and employee workstations are connected to the central computer network. They also train new users on how to use relevant hardware and software. Some network and computer systems administrators also manage telecommunication networks so employees can work from home or on the road, which has become increasingly important in recent years as more employees connect outside the traditional office setting.

As its low unemployment rate indicates, this is an in-demand profession that’s expected to grow as employers invest in new technology and faster mobile networks. More administrators will also be needed to implement upgraded security measures to protect workplace computer systems. The Bureau of Labor Statistics projects 2.5% employment growth for computer systems administrators between 2022 and 2032. In that period, an estimated 8,300 jobs should open up.

Network and computer systems administrator jobs often require a bachelor’s degree – typically in computer or information science, although sometimes a degree in computer engineering or electrical engineering is acceptable. Coursework in computer programming, networking or systems design will be helpful.

Some businesses require that an administrator get a master’s degree, while others are willing to accept an associate degree or professional certification along with related work experience. Completing certification programs and otherwise keeping up with new technologies is also important.

"It’s imperative to stay current with technology trends and changes by reading blogs, technology magazines and attending conferences," says Simran Sandhu, senior manager of network engineering services at Splunk, a software company based in San Francisco. "It’s also important to study and learn the basics of network technology and acquire an acute understanding of how information flows. Be able to identify key services such as DNS, DHCP and firewalls, and define the roles they play in a network infrastructure."
