Token-Ring sounds cool. I've never seen or used it, but i would like to try.

Token ring uses a ring topology between MAUs (Media Access Units) and drop links break into the ring through a relay. They run at 4Mhz or 16Mhz.

It differs from ethernet in a number of ways, the 802 frame is slightly different, it can contain routing information in the header, you don't get collisions and you can tell if a station received the packet as it flips a bit in the packet as it continues round the ring.

Is that the one that uses BNC cables/connectors?

No, that's 10Mhz thin ethernet, aka 10Base-2.
