Show Answer
WAN stands for “Wide Area Network” in networking. A WAN is a type of computer network that spans a large geographical area, connecting multiple LANs (Local Area Networks) and other networks together. Unlike LANs, which are typically confined to a single building, office, or campus, WANs can cover vast distances, often extending across cities, countries, or even continents. WANs are used to connect geographically dispersed locations, allowing data and communication to flow between them.
WANs can be established using various technologies, including leased lines, fiber optics, satellite links, and the internet itself. They are commonly used by organizations to connect their branch offices, data centers, and remote locations, enabling the sharing of resources and data over long distances. The internet itself can be considered a global WAN, connecting networks and devices worldwide.
