WANs

A Wide Area Network (WAN) is a computer network that connects devices and local networks over large geographical areas, such as cities, countries, or continents. It enables data to travel between distant locations, supporting activities like internet browsing, remote work, and international communication. The internet is the largest example of a WAN. WANs use special technologies and infrastructure, such as fiber optic cables and satellites, to transfer data quickly and reliably across vast distances, facilitating global connectivity and information sharing.
