A network administrator is an IT expert who manages an organization's network. The network administrator must have a high level of technological knowledge and, very often, is the highest level of technical staff within a given organization. Network administrators keep networks operational and monitor functions and operations within the network.
A network administrator is responsible for installing, maintaining and updating any software or hardware necessary to efficiently manage a computer network. The computer or computer network can extend to a local area network, a large area, the Internet, and intranets.
The network administrator generally has a higher level of computer science and information technology. Administrators also typically acquire network-related certificates or receive high-level training related to specific software or hardware included in the network. This allows the network administrator to quickly take control of new network additions or even create a new network entirely from scratch. Well-known organizations like Microsoft, Cisco, Redhat and Juniper offer certificates related to network administration.
Network administrators rarely participate in direct user assistance, such as help desk activities. Instead, they engage in high-level technological support, such as the maintenance of network hardware and software equipment and monitoring equipment to ensure general network operations. Network addresses are often assigned through the network administrator. In addition, network administrators configure the authorization and authentication of individuals or groups who access network resources.
Network administrators can also be technically involved in the administration and maintenance of desktops, servers, printers, switches, routers, firewalls, software implementations, security updates, VPN gateways, file servers, intrusion detection systems and a wide range additional technologies associated with software and hardware within the network.
