The consumer segment of a WAN generally does not own the communications lines that connect the remote computer systems; instead, the customer subscribes to a wide network service through a telecom provider.

Unlike LANs, WANs normally do not link individual computers, rather are used to link LANs. WANs also transfer data at slower speeds than LANs. WANs are also architecturally similar to metropolitan area networks (MANs) but facilitate communications links for distances more than fifty kilometers range

In terms of networking WANs are either point-to-point, including a direct assembly between two locations, or function across packet-switched networks, in which data are transferred in packets over shared circuits. Point-to-point WAN service may include analog dial-up lines, in which a modem is involved to attach the computer to the telephone line, or a committed leased telephone lines, also called a private connection.

Point-to-point WAN service suppliers involve both local phone businesses and long-distance carriers. The packet-switched network facilities are usually preferred by enterprises which have lesser volumes of data, for which multiple devoted lines would be a burden in terms of cost.

Based on the service, WANs can be functional for nearly any data-sharing purpose for which LANs can be utilized. Slower communication speeds, however, may make some requests less functional for WANs. The basic usage of WANs are for electronic mail and file transmission; however, WANs can also allow operators at the remote location to access and enter data on a central unit’s database. Such as instant refreshing accounting files.

Network-based software that enables productivity and production trailing, such as groupware and workflow automation software, can also be utilized over WANs. By using specialized tracking software, workers at different locations can more easily work together on projects from any location. The WANs also provides remote offices permission to a central processing team with the required data meant for communications services.
