Wide Area Network
15 definitions

Wide Area Network

Is a computer network that covers a broad area (any network whose communication links cross metropolitan, regional, or national boundaries). Or, less formally, a network that uses routers and public communications links. Contrast with personal area networks (PAN’s), local area networks (LAN’s), campus area networks (CAN’s), or metropolitan area networks (MAN’s) which are usually limited to a room, building, campus or specific metropolitan area (e.g., a city) respectively. The largest and most well-known example of a WAN is the Internet.

Wide Area Network

A group of computers linked within a network, such as, the Census Bureau's regional offices, to exchange and share information. A local area network may link computers within a building or among several buildings, whereas a WAN covers more area and distance. See local area network.

Wide Area Network

A WAN covers a wider geographic area than a LAN, is an integrated voice or data network, often uses common carrier lines for the interconnection of its LANs, and consists of nodes connected over point-to-point channels. Commercial examples are Internet and public data. Government examples are NIPRNET and SIPRNET.

Wide Area Network

A wide area network (WAN) connects many local networks (LANs) or metropolitan area networks (MANs) together to provide limited resource sharing among the connected networks. A WAN consists of low-speed lines (that is, modems) to high-speed links. WANs are usually used to provide access to information (such as file sharing), rather than resource sharing of devices such as printers and disks.

Wide Area Network

Wide Area Network; communications network that uses such devices as telephone lines, satellite dishes, or radio waves to span a larger geographic area than can be covered by a LAN.

Wide Area Network
