Topology means how a network is set up. Token Ring topology is one of them. It means that several computers are connected in a ring. When one computer wants to send data to another, it has to catch a free token which gives the permission to send data. As soon as one particular machine gets the token, it has the control over the whole network which means no other computer can send data. Then it puts its destination address and the data on the token, and sends the token to the machine that¡¦s next to it. If the next machine is not the destination, it will pass the data on and on until it gets to the address. When the addressed station gets the data, it can not k
Third, a computer on a Bus network has to wait for the network to be clear in order to send data packets. After the initiator receives the message and reads the acknowledgment, the free token can be released onto the ring. However, Token Ring topology prevents collisions from setting a token on the network, so there's always only one transmission of data at certain time. There are similarities and differences between Token Ring topology and Bus topology. Second, for Ethernet, when computers get messages which do not belong to them, they will not keep them and pass them on. Finally, collisions occur on a Bus network. eep the message and release the token. It copies the data, then it sends the message back to the initiator with the acknowledgment to say that it has received the data. Every machine on the network will keep passing on the data until it gets to its destination. asp) It is also capable of fast data communication over long distances. There are advantages and disadvantages to Token Ring topology.
