A WAN (Wide Area Network) is a telecommunications network that extends over a large geographic area, such as cities, countries, or even continents. It connects multiple LANs (Local Area Networks) or other types of networks, enabling communication and data sharing across wide distances. WANs typically use leased lines, satellite links, or public internet connections to transmit data. One of the most common examples of a WAN is the internet itself, which connects millions of LANs worldwide. WANs often offer lower data transfer speeds and higher latency compared to LANs, but they provide essential connectivity for global business operations and communication.
