How is the operation of 802.4token bus?
A token bus uses a shared bus for communication. Hosts on the bus are ordered in a logical ring, with access to the bus coordinated by passing a token (a special packet) around the ring, indicating permission to transmit. The intent is to get the robustness of a simple bus protocol with the deterministic response time of a token ring. Unfortunately, because the bus is shared, each host on the bus must wait for the token to be completely transmitted before it can pass it on. This is in contrast to a token ring, where the token passes through each host with only a few bits delay. This gives the token bus considerably worse latency than a token ring. The reliability of a token protocol over a (CSMA protocl such as Ethernet ) is undermined by the complex protocols needed to recover the token at exactly one host should it become corrupted.
Discuss the difficulties that one encounters when trying to build a bridge between the various Ethernet Token Ring and Token Bus LANs.?
Since there is no protocol known as Ethernet Token Ring I assume you are asking about the difference between Ethernet, Token Ring, and Token Bus usage. These are all different protocols, so connecting all three types of networks is not practical. Token Bus networks were an early attempt to get mainframes to connect to terminals through a bus topology structure, utilizing a token for arbitration. Those networks typically ran at 4 Mbps. They were also subject to the same problem as a linear bus structure with Ethernet, which is a break in the cable would bring down the entire network. A later version of Token ring uses a ring topology structure, where a failure in the network will not bring down the entire network. It still uses a token for station arbitration, but can ran at 16 Mbps. Newer versions of HSTR can run at 100 Mbps and there is a standard for a gigabit version. Chances are you will need to bridge between Ethernet and Token Ring (not token bus). For that, you will need a bridge, router, or gateway that can convert between the protocols. In some cases the media is different as well, going from coaxial cable to unshielded twisted pair (UTP). So the difficulties are in correctly converting the protocols between the two, connecting different media types together, and troubleshooting problems between the two networks.
Difference between IEEE 802.3 AND 802.4?
IEEE 802.3 is the standard for Ethernet LAN. It is a collection of IEEE standards for physical layer and Data link layer's MAC sublayer. According to these standards, the Ethernet LAN card works. IEEE 802.4 is a Token Bus standard which was standardised by IEEE. It grants the Bus physical topology to use token messages to access physical layer.
What is difference between Token Ring Token Bus?
In a token bus network architecture, the nodes at either end of the bus do not actually meet. In a token ring, the network logically functions as a ring, but is wired as a star.
What is a sentence for the word token?
You can't get on the bus without a token.
Difference between token ring and Ethernet bus?
Token bus is as far as I know the theory that token ring's transmission is based on. Both physical layers of networking, can be said that they were two competing set of networking technology, both initial members of IEEE 802.x networking family. Token ring is based on passing packets along a track from one station to another like a passenger in a train, for fail-safe redundancy there were 2 duplicate tracks can be thought as one clockwise one counter-clockwise in a ringed/circular arrangement. Ethernet is rather about shooting packets from source to destination. If there is another packet being shot a collision is this, the packets are lost and shooters agree to re-shoot at a random time hopefully and likely so avoid the collision again, but if it happens again do it again and again...
The bus cable to which computers on the Ethernet is connected?
The bus cable to which computers on the Ethernet is connected is called the trunk. If the trunk breaks, a bus topology is completely disrupted.
