it is a network data communication system where each of the device connected with it wait for their time to communicate. when they have the token, they got to communicate or sent transmission.
Token Ring and FDDI networks can.
Token ring
Both Token Ring and FDDI use the concept of a ring topology structure. However, Token Ring is used in a LAN, and FDDI is used in a MAN.Token Ring is implemented with copper cable (UTP cable) and FDDI uses Fiber Optic cable.Finally, the protocols are very different between the two. FDDI uses a synchronous type of transmission, where Token Ring uses an actual token (a 3 character packet) to control who has access to transmit or receive on the network. FDDI does not use this technique.
You may be thinking of a token-ring network.

Token ring hub
It is a 'token' of your affection for that person.
In a token bus network architecture, the nodes at either end of the bus do not actually meet. In a token ring, the network logically functions as a ring, but is wired as a star.
That is not possible. In Token Ring, only the station with the token can transmit.
Token Passing
IBM created the token ring architecture, which was used for years primarily by Novell.
