What Does a Network and Computer Systems Administrator Do?

Computer networks are critical to business. Network systems administrators are the ones who keep those networks healthy and dependable. They are responsible for the day-to-day operation of computer networks, including local area networks (LANs), wide area networks (WANs) and intranets. They analyze an organization’s computer needs and install the necessary hardware and software.

The scope of work in a network systems administrator’s daily job will depend on the size of the company. For example, all administrators will manage company servers as well as desktop and mobile equipment, but in a bigger company, an administrator may supervise the person who provides technical support to users.
