Wide Area Network (WAN)
A Wide Area Network (WAN) is a telecommunications network that extends over a large geographic area, connecting multiple smaller networks such as Local Area Networks (LANs) or Metropolitan Area Networks (MANs). WANs enable data communication and resource sharing among devices across cities, countries, or even globally. They are essential for businesses with multiple locations, allowing for centralized data management, collaboration, and communication over vast distances, often utilizing leased telecommunication lines or satellite links.
