Token Ring

A computer network configuration in which all the computers are arranged on a ring. A token, which is a special bit pattern, travels around the ring. To send a message, the host must be in receipt of the token; this is attached to each message that is sent. Once the host has completed its transmission the token is then released, to the next host requiring service. This process continues and is used as the basis for contention resolution.
