There seems to be some confusion over FDDI. Well, I've done enough work with FDDI, so maybe I can clear up a few things.
FDDI is a fiber optic protocol (Fiber Distributed Data Interface), with a token-based double wire transmission scheme. A FDDI network usually consists of a main ring, which can have concentrators branching off it. The main ring passes a token in one direction around the ring, while data goes the opposite direction over the other fiber. It's a 100 Mbps protocol, usually used for connecting high-performance computers or for backbones. If anyone has any more questions about FDDI, I can try to answer them, but I'm not really an expert, so don't get TOO technical :)
