Token Ring
The token is a special 3 byte sequence that indicates the state of the ring; it may mark the ring as in-use, or free (anyone can use it), or health status. Any client needs to have access to the token before transmitting or receiving on the ring network.

token ring uses a physical star and a logical ring ,while FDDI uses a physical star/ring and a logical 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.

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.
3. Unlike Ethernet, Token Ring uses a ring topology whereby the data is sent from one machine to the next and so on around the ring until it ends up back where it started. It also uses a token passing protocol which means that a machine can only use the network when it has control of the Token, this ensures that there are no collisions because only one machine can use the network at any given time.
