AppleTalk is a local area network communication protocol originally created for Apple computers and run over a LocalTalk network. An AppleTalk network can support up to 32 devices and data can be exchanged at a speed of 230.4 kilobits per second (Kbps). Devices can be as much as 1,000 feet apart. AppleTalk's Datagram Delivery Protocol corresponds closely to the network layer of the Open Systems Interconnection (OSI) communication model.
