A network administrator has the challenging task of ensuring that the equipment and programs which are used to connect computers to a server, are running efficiently. Due to their technical expertise, these administrators may also be known as network technicians. The connections may be between a few personal computers in the same room, or a huge communications network that spans the globe. The job of establishing connectivity is enormous, because the software and hardware communicate on many different levels.
A university network administrator, says the need for network administrators evolved as personal computers became the norm in organisations. 'When people began to connect PCs together so they could share information, they found it was easier to have one central server which was connected to all the PCs. The development of network software meant that access, file space and a range of other things could be controlled at a single point, rather than on each machine.'
A network administrator is the person in charge of maintaining the central server and its functions. To do this they must plan and install the hardware and software that comprises the network and maintain the printers connected to the network. This could include LAN, WAN, Internet or Intranet systems. They may also assess future IT requirements for the organisation.
