In computer networking, the term WAN stands for Wide Area Network. A WAN is a type of network that spans a large geographical area. It connects multiple smaller networks, such as local area networks (LANs), across cities, countries, or even continents. WANs are essential for enabling communication and data exchange between users in different physical locations.

The internet is the largest example of a Wide Area Network. Other examples include private networks used by multinational companies to link their offices in various cities or countries. These networks are typically maintained using leased telecommunication lines, satellite links, or public networks configured with security measures like VPNs.

The term Wide refers to the extensive geographic coverage, often beyond the limits of a single building or city. Area describes the physical scope of the network, and Network refers to the interconnected system of computers, servers, and devices.

Incorrect options such as Wired Area Network, Web Access Network, and Wireless Access Node are not valid terms in the context of WAN. The standard and correct full form is Wide Area Network, which plays a vital role in enterprise infrastructure, cloud computing, and global internet connectivity.
