Q. Explain working of Ring Topology?
Ring Topology: In ring topology, all user nodes are connected with physical path acting as links of a chain and last user node is connected back to the first node. A signal going on to the next node should be processed by the first node, which then passes it through to next node. Adding a new user requires breaking the ring temporarily, inserting new node and then re-establishing complete ring path. Rings also have simpler protocols than buses. In bus configurations, every node should monitor the bus constantly to see if there are any messages for it or to see if bus is clear before transmitting. Ring usesa simpler scheme.
