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.
