what is a wan

Whatis a Wan? A wide area network is a network that exists over a large-scale geographical area. A WAN connects different smaller networks, including local area networks (LANs) and metro area networks (MANs). This ensures that computers and users in one location can communicate with computers and users in other locations.

A wide area network (WAN) is a telecommunications network, usually used for connecting computers, that spans a wide geographical area. WANs can by used to connect cities, states, or even countries. Unlike LANs, WANs typically do not link individual computers, but rather are used to link LANs.

A LAN (local area network) is a group of computers and network devices connected together, usually within the same building. A WAN connects several LANs, and may be limited to an enterprise (a corporation or an organization) or accessible to the public.
