They enable communication and data transfer between different locations, allowing organizations to connect their branches or offices spread across a wide area. WANs utilize various technologies, such as leased lines, satellite links, and internet connections, to establish connectivity over vast distances. Local Area Network (LAN) is a network that covers a small area, like an office building or a home. Metropolitan Area Network (MAN) is a network that spans a city or metropolitan area.
