WAN

A Wide-Area network, or WAN, is spread out geographically and so requires long-distance connections between locations. WANs use routers to direct traffic to the appropriate subnet or LAN. Some companies lease telecommunications lines, called "private circuits," to connect sites on their WAN. Others rely on VPN tunnels over the public Internet to allow remote users to log on to the WAN. In addition to leased lines, which can be expensive, WANs can use circuit-switching or packet-switching techniques.
