RING TOPOLOGY
This topology is a simple design and consists of a single cable that forms the main data path in the shape of a ring. Each device is connected to a closed loop of cable. Signals travel in one direction from one node to all other nodes around
the loop.
In this type each computer is connected to the next computer with the last one connected to the first.
Each retransmits what it receives from the previous computer. The message flows around the ring in one direction.
The ring network does not subject to signal loss problem as a bus network experiences.
There is no termination because there is no end to the ring.
Advantages:
1) Each node has equal access.
2) Capable of high speed data transfer.
Disadvantages:
1) Failure of one computer on the ring can affect the whole network.
2) Difficult to troubleshoot the network.
