IT network administrators are responsible for supporting groups of computers and other technology devices that are interconnected and communicate using different computer technologies, such as local area networks (LAN) and wide area networks (WAN). IT network administrators are responsible for both the hardware and software that is required to build, configure and maintain a LAN and/or WAN. They also troubleshoot the organization's network infrastructure when problems arise. Network administrators have knowledge and understanding of servers, firewalls and routers as well as a strong background in network design, implementation and network connectivity experience.
Since network administrators are responsible for organizations' ability to communicate and share data with other computers, both within the organizations' locations and across other data sharing mediums (such as the Internet and virtual private networks), they also provide and enforce the security rules and policies that control access to the organizations' network(s), as well as the policies that control the organizations' network maintenance and support operations procedures.
Network administrators also are responsible for keeping an organization's network operating at optimal levels all times; this is measured in terms of network up-time. They also provide hands-on support to network operations center (NOC) staff to diagnose and resolve network issues. In addition, they make recommendations for network upgrades--in both hardware and software--as required to an organization's chief technology officer. Network administrators are usually required to hold a degree in computer science or a related field.
