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.
A networking methodology in which the backbone and switching components are combined into a single device.In a traditional network, local area networks (LANs) are multipoint connections connected using a backbone cable.For example, in a building, a fiber-optic backbone might run from floor to floor and connect with a hub in a wiring closet on each floor.he advantages of using a collapsed backbone are that they eliminate the costs of backbone cabling installation, they require fewer devices, their equipment administration is more centralized, and they offer higher available bandwidth for each station.
