Ring topology

4) Ring topology

In this topology, each computer is connected to the next, and the final device is connected back to the first so that the entire system is a closed loop.

                Any single devices on the ring is connected directly two neighboring devices at all time. There are both single ring topology and dual ring topology.

                Data travel around the ring in a single direction, either   clockwise or counterclockwise direction. In dual ring system, data can travel in both direction to speed up through put.

                Unlike bus topology, ring topology required n caballing termination because the cable never really starts and end.
