A computer network that spans a relatively large geographical area. Typically, a WAN consists of two or more local-area networks (LANs).

Wireless is a term used to describe telecommunications in which electromagnetic waves (rather than in the form of wire) carry the signal over part or all of the communication path.

Wireless Lan is a type of local-area network that uses high-frequency radio waves rather than wires to communicate between nodes.

Workstation is a type of computer used for engineering applications (CAD/CAM), desktop publishing, software development, and other types of applications that require a moderate amount of computing power and relatively high quality graphics capabilities.

Like personal computers, most workstations are single-user computers. However, workstations are typically linked together to form a local-area network, although they can also be used as stand-alone systems.
