Which category of network does a WAN connect?

A WAN, or Wide Area Network, is specifically designed to connect computers and devices over long distances. This category of network facilitates communication and data transfer between users and systems that are geographically dispersed, which can range from cities to countries or even globally. WANs typically use technologies such as leased telecommunication lines, satellite links, and other methods to ensure that data can travel over substantial distances effectively.

The characteristics of a WAN make it suitable for connecting remote offices, branch locations of a business, or users in different regions, who require access to shared resources or applications. This contrasts with other networking categories: local devices within a home would fall under a Personal Area Network (PAN) or Local Area Network (LAN), which serve smaller areas. Similarly, devices across small geographical areas would also be covered by LANs, while wireless devices within a range would pertain to Wireless Local Area Networks (WLANs). Hence, the defining attribute of WANs is their capability to span extensive distances, making them essential for large-scale networking needs.
