Wide Area Network
the connection of computers and networkable devices that spans over a large distance
Synonyms, Abbreviations or Trade Names: WAN
Layman's Definition: The Internet is the largest wide area network, but two or more local area networks connected over a large geographical area can also be a wide area network. Using the restaurant analogy an example of a wide area network could be the delivery system used by a chain restaurant company to get partially prepared food from the company’s warehouse to its restaurants spread apart by a large distance.
