Is ring topology robust?
In Ring Topology, each device/node is connected with its neighboring node forming the shape of ring hence it is known as Ring Topology. In ring topology the data circulate from one computer to another. The flow of the data in ring topology can be uni-directional or bi-directional.
The data flow in the ring topology is based on the Token Passing principal, The token is passed from one computer to the next, only the computer with the token can transmit. The receiving computer takes the data from the token and sends the token back to the sending computer with an acknowledgment signal. After verification, the token is regenerated. Only those computer will transmit the data whose have the token. Other computers have to wait for an empty token to reach them. This network topology is usually found in schools, small building, and offices. In case of any failure in a computer or cable breaks the entire network can be shutdown. Advantages of Ring Topology:
