Abstract
The ability to interconnect computers into networks is not new. Networks can be formed by telephone lines, modems, or special data switchers. Modern local exchanges, such as the PBX, allow both telephone and data traffic to be used on the same wiring. In a sense, this is a local area network, but it differs from those commonly used today. LAN data transmission differs from that of telephone-based technologies in three categories:
-
The wiring, or medium, in a LAN is shared by a number of devices, with no separate wires for each device in a network.
-
The communication in a LAN is peer-to-peer; that is, any device can communicate with any other device directly. In traditional systems, communication is with or through some third device such as a central switch or a host computer.
-
The data rate in a LAN is much greater than in traditional networks—10M bps versus 9.2K bps.
