Wide Area Network (WAN)

A Wide Area Network (WAN) refers to a computer network that covers extended geographical regions connecting various Local Area Networks (LANs) or other networks across large cities and countries. While LAN covers smaller areas like homes, schools, or offices, businesses use WANs for global connectivity. The speed at which data transfers through WAN is generally slower than that in LAN because it spans longer distances involving several servers/terminals in between.

The speed ranges from a few kilobits per second (Kbps) to megabits per second (Mbps). The major challenge encountered while operating this system arises from signal distortion caused by propagation delay. WAN is typically owned by telecommunication firms or internet service providers using public/private infrastructure such as satellite links, leased lines, fiber optics, and Wi-Fi.

Routing among these systems requires sophisticated routing and switching technologies to efficiently route data packets from the source to the intended receiver. Wide area networks are essential for providing comprehensive connectivity through establishing communication between various organizational branches or remote locations. With the capability of interlinking LAN, companies can share resources seamlessly while facilitating collaborative work efforts and data exchange over vast geographic areas. For instance, in a multinational business operating out of different cities, the WANs interconnect its local networks and give employees access to shared resources, databases, and applications regardless of their physical location.
