How is a FDDI network like a Token Ring network How is it different?
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.
