Wide Area Network (WAN)

A Wide Area Network (WAN) is a large-scale network that connects computers and other devices across long distances, often spanning cities, countries, or continents. Unlike local networks confined to a single building or campus, WANs enable communication and data sharing over extensive areas, typically using technologies like leased lines, fiber optics, or satellite links. The internet is the largest example of a WAN, facilitating global connectivity. WANs are essential for businesses and organizations that require remote offices, mobile access, and interconnected systems to work seamlessly across vast geographical locations.
