A wide area network (WAN) is characterized by its vast interconnection of devices across large geographical distances. WANs connect multiple local area networks (LANs) and encompass the use of various communication technologies, such as satellite, leased lines, and microwave links. They enable organizations to connect remote offices, branch locations, and mobile users, facilitating seamless communication and data sharing across diverse locations. WANs play a vital role in supporting global operations for businesses.
