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. A common question for the small-medium business (SMB) network administrator is, how much bandwidth do I need to run my business? Typically, within a larger organization, these roles are split into multiple roles or functions across various divisions and are not actioned by the one individual.

Within smaller organizations, the more senior role of network engineer is sometimes attached to the responsibilities of the network administrator. It is common for smaller organizations to outsource this function.Wisegeek.com - What is a Network Administrator? - by Malcolm Tatum edited by Bronwyn Harris: Retrieved December 22, 201
