One way to categorize the different types of computer network designs is by their scope or scale. For historical reasons, the networking industry refers to nearly every type of design as some kind of area network. Common types of area networks are: LAN - Local Area Network. WAN - Wide Area Network.
Bridged LANs can span arbitrary distances when using a satellite channel for the bridge. The resulting network is still considered a LAN and not a WAN. To be considered a WAN, a network must be able to connect an arbitrary number of sites across an arbitrary distance, with an arbitrary number of computers at each site. network is a system of hardware and software, put together for the purpose of communication and resource sharing. A network includes transmission hardware, devices to interconnect transmission media and to control transmissions, and software to decode and format data, as well as to detect and correct problems.
