RING TOPOLOGY

  • On a ring network, a cable forms a closed loop (ring) with all computers and devices arranged along the ring.

How data is transmit :
  • Data transmitted on a ring network travels from device to device around the entire ring, in one direction (clockwise or counterclockwise) until it reach its destination by using token.
  • Token passing is one method for sending data around a ring.
  • Each device takes a turn sending and receiving information through the use of token.
Advantages :

1. All computers have equals access to the resources in the network.
2. The uses of token passing enables all devices in a ring topology to share network resources fairly.

Disadvantages :
 
1. A failure in any cable or device breaks the loop and can take down the entire network.
2. A ring network can span a larger distance than a bus network, but it is more difficult to install.
