Similar to wide-area networks, local-area networks are an example of communication networks interconnecting several devices for information exchange. The LAN design is usually for a single floor or building, but it can also reach to multiple buildings via routers and bridges. The design is shared medium rather than switching nodes. The internal data rates for LANs are greater than for wide-area networks.
