Ring network topology

This type of network uses a ring in which data is passed from node to node, either in a clockwise or an anti-clockwise direction. Normally a token is passed from node to node, and a node can transmit when it gets the token.
In a ring network, computers link together to form a ring. To allow an orderly access to the ring, a single electronic token passes from one computer to the next around the ring.

A computer can only transmit data when it captures the token. In a manner similar to the star network, each link between nodes is a point-to-point link and allows the usage of almost any type of transmission medium. A typical ring network is ABM Token Ring.
