What does the acronym WAN stand for in networking?

The acronym WAN stands for Wide Area Network. This term refers to a telecommunications network that extends over a large geographic area, typically covering multiple cities, countries, or even continents. WANs are used to connect smaller networks—like Local Area Networks (LANs)—so that they can communicate and share data across long distances. The use of WANs is essential for organizations that operate in multiple locations, as it allows for data exchange and connectivity between scattered sites.

In contrast, the other terms do not represent the concept of a WAN. Wireless Area Network refers to a local network that relies on wireless signals for connection, while Local Area Network pertains to a network that is restricted to a small geographic area, such as within a single building. Wired Access Network is not a standard term used in networking. Therefore, the proper expansion of WAN accurately reflects its purpose and functionality in networking.
