AppleTalk networks
A network is a communication system that connects computers to share information using network services,
such as electronic mail, print spoolers, and file ser vers. Information is transferred over a cabling system or
WAN using a common set of protocols. You can think of the cabling system as an organization of cities, streets,
and buildings and the protocols as the method of sending letters or packages, as illustrated on the following
pages. A cable is the physical medium (for example, twisted pair or coaxial) over which information travels from
one device to another.

AppleTalk protocol
AppleTalk is a protocol set for local area networks developed by Apple Computer. While initially applied to the
LocalTalk cabling system for connecting Macintosh computers and LaserWriters, it has been expanded to use
other cabling systems, such as Ethernet, as well as the dial-up telephone networks and packet switching
systems. LocalTalk was originally known as the AppleTalk Personal Network system.

Each computer or peripheral device (printer, client, file ser ver) connected to a network is called a node and has
a unique node address, which can be any number from 1 to 254. Whenever you open the Chooser or any
application that communicates with other computers on your network, your application compiles a list of all
node names and addresses. All you see are the names --- for example, “Paul’sMac,” “TechSpor tsWriter,” or
“2nd Floor AppleShare” --- but your application also knows the node addresses of all these devices.

When you send information, commands, or requests to a printer, ser ver, or another workstation, your
application formats the information into units known as packets. It then attaches the correct address to the
packets and sends them to the AppleTalk software on your computer, which for wards the packets across the
network. Packets also include a return address, so the receiver will know where to reply.
