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.
Token Ring is described by the IEEE 802.5 standard. This standard defines the physical and data link layers for Token Ring networks, which use a token-passing protocol for controlling access to the network. Token Ring networks typically operate at speeds of 4 Mbps or 16 Mbps and utilize a star topology with a token that circulates around the network to manage data transmission.
Token
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.

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.
It is a 'token' of your affection for that person.
