What Is AppleTalk?
AppleTalk, Apple Computer's proprietary system for networking computer users, first became available in the early 1980s. This networking system allowed participants to share printers, files and other resources.

Individual Units
-
In an AppleTalk network, each terminal or device, also called a node, runs a series of data processes known as sockets that identify and permit network activity between the nodes. A single data cable connects multiple nodes in a network.
Network Zones
-
When system administrators create multiple networks through AppleTalk, they assign them in logical arrangements known as zones. These zones can share information within the larger network while remaining semi-autonomous in everyday operations.

Types
-
AppleTalk supports either extended networks that can use multiple network numbers or non-extended networks assigned a single network number. Phase 1, Apple's first version of the system, limited itself to non-extended networks of up to 135 servers and hosts per network segment. Phase 2 later added extended network capability for up to 235 servers and hosts.
