6.4.4 WAN
A Wide Area Network (WAN) can span a radius of up to 1000 km. Therefore, a WAN can connect across countries
and continents. WANs are used for long-distance communication and are well-suited to connect remote areas. A
WAN connects various local and metropolitan area networks using network devices such as bridges and routers. The
Internet is a common example of a WAN. A WAN is typically managed and owned by a single organisation. Setting up a
WAN is costlier than setting up a LAN. WANs typically use leased lines and satellite links as transmission media. Figure
6.13 shows a WAN that connects various LANs and MANs.
