The common implementation of this topology is token ring . A break in the ring causes the entire network to fail. Individual workstations can be isolated from the ring. Bus The bus topology connects workstations using a single cable. Each workstation is connected to the next workstation in a point to point fashion.
All workstations connect to the same cable.
If one workstation goes faulty, all workstations are affected. Workstations share the same cable for the sending and receiving of information. The cabling costs of bus systems is the least of all the different topology's. Each end of the cable is terminated using a special terminator. The common implementation of this topology is Ethernet .
