LANs The next characteristics differentiate one LAN from another: · network topology - the geometric arrangement of devices on the network. ·Protocols - the rules and encoding specifications for sending data on a network, including guidelines regulating access method, allowed physical topologies, types of cabling and locomote of data transfer, e.g. Ethernet, LocalTalk, Token Ring. ·Media - how devices are connected (e.g. cable or radio waves) Topology...
