A network administrator is the person designated in an organization whose responsibility includes maintaining computer infrastructures with emphasis on networking. Responsibilities may vary between organizations, but on-site servers, software-network interactions as well as network integrity/resilience are the key areas of focus. A network administrator is an Information Technology expert who manages an organization’s network. The network administrator must possess a high level of technological knowledge and is most commonly 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 upgrading any software or hardware required to efficiently run a computer network. The Information Technology or computer network may extend to a local area network, wide area network, the Internet and intranets.
The role of the network administrator can vary significantly depending on an organization’s size, location, and socio-economic considerations. Network administrators are responsible for making sure that computer hardware and network infrastructure related to an organization’s data network are effectively maintained. In smaller organizations, they are typically involved in the procurement of new hardware, the rollout of new software, maintaining disk images for new computer installs, making sure that licenses are paid for and up to date for software that needs it, maintaining the standards for server installations and applications, monitoring the performance of the network, checking for security breaches, and poor data management practices.
