Wide Area Network (WAN)
Wide Area Network (WAN), its scope covers a wide geographical area, often covering a country or even continent. WAN consists of a collection of machines that aims to implement programs (applications) user.

Usually to do this requires a machine called a gateway in order to establish relations and carry out the necessary translation, both hardware and software.
