Workstation or client The computer that accesses network resources.
Server The computer that provides the resources.
The network administrator can configure the network, control user accounts, and manage network security.
Because many computers can operate on one network, the entire network can be efficiently managed from a central point (a network administrator). Consider the previous example and suppose that a new version of Excel became available to the data analysts. With individual computers, each system would have to be upgraded and checked separately. That's not such a big deal with only two systems, but when there are dozens (or hundreds) of PCs in the company, individual upgrades can quickly become costly and impractical. With a network, an application only needs to be updated on its server oncethen all the network's workstations can use the updated software immediately. Centralized administration also allows security and system monitoring to take place from one location.
Wide area network (WAN) A network intended to cover a wide geographical area. An example of the ultimate WAN is the Internet with its global reach.
