A WAN consists, basically, of two or more LANs (Local Area Network), which are machine-accessible to each opposite victimisation WAN technologies under a high-speed communication. The largest and believably the outmatch example of a Wide Area Network is the cyberspace. WAN technologies generally function at the lower three layers of the OSI clay sculpture: the Physical socio-economic class, the Data physical contact Layer, and the Network Layer (all layers are shown in effectuate below). . Bridges, routers and multiplexers and opposite devices are used for counterbalance information transmission.

Some WANs are extremely widespread ( world(prenominal)), still most do non provide true global coverage. Organizations supporting WANs using the Internet Protocol are cognize as Network advantage Providers (NSPs). These form the effect of the Internet. The OSI (Open body Interconnection) Model: - Application Presentation Session Transport Network Data Link Physical Addressing and routing On a Wide Area Network, the routing of data is make mainly using transmission control protocol/IP (Transmission crack protocol/Internet Protocol).
