For example, the Printer Access Protocol is used between end node clients and printers or print servers to download files for printing. AppleTalk addresses are 24 bits long. In the AppleTalk network topology depicted on the right, we illustrate two networks connected via a router, one with a single network number of 53, the other with network numbers assigned in the range 20-25. An AppleTalk network is logically divided into areas called zones . Each node in an AppleTalk network belongs to one and only one zone.
Extended networks can have multiple zones.
Names Name Binding . Named NVEs are associate with or bound to their network addresses through the name binding process. Name binding may be performed when a node first joins an AppleTalk network, or dynamically, immediately before the first use of a name. AppleTalk is a plug and play architecture. A node proposes an AppleTalk address for itself, broadcasts the address over the network, and waits for a reply from any other node on the network claiming that the address in the probe is already in use.
