AppleTalk was developed by Apple, Inc. for computer networking. AppleTalk is a set of protocols included in the original version of Macintosh in 1984. Unlike other early LAN systems, AppleTalk was based on the OSI model of protocol layering and was not built on the archetypal Xerox XNS system, although several portions of the AppleTalk system have direct analogs in XNS.

AppleTalk contained two protocols, AppleTalk address resolution protocol (AARP) and name binding protocol (NBP) in order to make the system entirely self-configuring. Through AARP, AppleTalk hosts were able to automatically generate their own network addresses.

NBP mapped network addresses to user-readable names, essentially making it a dynamic Domain Name System (DNS). Routers, however, were able to provide all the information by overriding the default mechanisms. This was beneficial for larger networks, since "chattiness" could occur through AARP as new nodes searched for free addresses.

The two protocols also made AppleTalk the easiest to use among networking systems, making installation of new machines simple, requiring only that they be plugged in and optionally be given a name. A program called the Chooser listed down and classified the machines on a local network through a completely automated procedure.

On larger networks and wide area networks (WAN), the naming services provided by AARP and NBP caused a significant amount of unwanted traffic. This problem was addressed by the introduction of AppleTalk Phase 2.

An AppleTalk address consisted of four bytes: a two-byte network number (obtained from a router), a one-byte node number (chosen by each node), and a one-byte socket number. Names for services were chosen by humans so that they would easily be recognizable by users. They were long enough in order to minimize the chance of conflicts.

Though AppleTalk was originally intended to be part of a project known as Macintosh Office consisting of a host machine that enabled routing, printer sharing and file sharing, development of the Macintosh Office project was halted in 1986. In place of Macintosh Office, the AppleShare File and Print Server was released.

TCP/IP was the default networking model for the Mac; however, AppleTalk is backwards compatible with several products. For TCP/IP-based networks, an Apple implementation called Bonjour provided discovery and configuration services not unlike that of AppleTalk.

How do routing protocols and routable protocols differ?

A routing protocol refers to a protocol that is only used between routers, such as OSPF and EIGRP. A routed protocol, meanwhile, refers to a protocol wherein data can be routed, such a IP, AppleTalk, and IPX.

What reason might you use multiple frame types on a network?

If you use several different protocols (such as TCP/IP and IPX/SPX or Appletalk) then the frame types will be different. Networks can (and do) utilize several different protocols depending on what they need to talk to as clients.

Compare the osi model and tcp-ip model and their associative protocols?

The OSI model encompasses all of the TCP/IP sub-protocols plus several other protocols that are not part of TCP/IP. These would include IPX/SPX, NetBEUI, Appletalk, and other proprietary protocols that are not part of the TCP/IP model.

Is TCP IP used for everything?

No, TCP/IP is the not the only protocol used in the world, but it is certainly one of the most popular. Older networks may still use IPX/SPX (Novell) which is a competitor to TCP/IP. Mainframes use SNA or LU6.2 protocols which are very different from TCP/IP. Appletalk is also a competitor to TCP/IP.

What is a characteristic of the LLC sublayer?

In computer networking there is a seven layer OSI model and the LLC or logical link control layer is a data communication protocol layer which is the upper sublayer of the second OSI layer known as the data link layer. The main characteristic of the LLC sublayer is that it provides multiplexing mechanisms that allow for a number of different network protocols like IPX, AppleTalk and IP to work over the same network as well as allow them to exist together within a multipoint network.

What connecting device do you use for two or more connected networks?

For two or more connected networks you can use a bridgeto connect them all together.It depends on the two networks. A bridge can only connect two networks of the same type (eg Ethernet or Token-Ring), that also use the same layer 3 network address (eg IP subnet or IPX network #, or AppleTalk network #).A "gateway" device can connect two dissimilar types that share a network address, and a router can connect two networks of different network addresses whether or not they have the same network type.
