Glossary Web explains WAN
Wide Area Network connects more than one LAN and is used for a large geographical area. It is similar to a bank system where hundreds of branches in different areas are connected with each other to share details and all their official data. A wide area network works in a similar fashion to the LAN, just on a large scale. Normally, TCP/IP is the protocol that is used for a WAN in combination with the devices including switches, routers, and modems, etc.
