A WAN is a network that uses long-range telecommunication links to connect networked computers over long distances. A WAN usually consists of two or more LAN’s which are connected through public networks like the telephone system we use to make phone calls fro home or work. WANs use telecommunication links to make communication over a long distance possible. There are two types of WAN’s, enterprise WAN and global WAN. An enterprise WAN is usually owned by a company or an organization unlike a global WAN which is not owned by one company or organization and has the ability to cross national boundaries.
An example of a WAN would be a company that has locations in different cities or countries which are networked together and share information using the internet or public telecommunication lines to share information privately and securely. This kind of a WAN would consist of PC’s, Routers, TCP/IP Protocol, and other devices that would be used to transfer and receive information to and from each other.
Another example would be local, state, and federal police agencies. Each local police headquarters is setup to share information amongst the different departments when needed. This does include multiple LAN’s but housed in the same building. They then send information to the Federal and State agencies. They also relay information amongst other agencies in the same state or across the nation. It is very complex as to the function of every component because they all can operate independently as their own separate network.
