Which type of network extends over a large geographical area?

A Wide Area Network (WAN) is designed to cover large geographic areas, often spanning cities, countries, or even continents. WANs typically connect multiple Local Area Networks (LANs) and can utilize various transmission technologies such as leased lines, satellite links, or even public internet protocols. The primary function of a WAN is to facilitate communication and resource sharing among users in geographically separated locations, enabling businesses and organizations to operate effectively over large distances.

In contrast, Local Area Networks (LANs) are confined to small areas like a single building or campus, while Metropolitan Area Networks (MANs) are designed for a larger scope than LANs, usually within a city or large campus. Campus Area Networks (CANs) serve a specific set of buildings in a defined area, like a university or corporate campus, but still do not reach the extensive coverage that WANs provide.
