RING TOPOLOGY
In Ring Topology, computers
are placed on a circle of cable. Every node has exactly two neighbors for
communication purposes.
All messages
travel through a ring in the same direction (clockwise or counterclockwise)
until it reaches its destination. Each node in the ring incorporates a
repeater. When a node receives a signal intended for another device, its
repeater regenerates the bits and passes them along the wire.
Advantages of Ring Topology
§ Ring Topology is easy to install and reconfigure.
§ Every computer is given equal access to the ring.
Hence, no single computer can monopolies the network.
Disadvantages of Ring Topology
§ Failure in any cable or node breaks the loop and can
take down the entire network.
§ Maximum ring length and number of nodes are limited.
