Ring
Ring topologies are most often seen in Token Ring and FDDI networks, both of which are discussed later in the chapter.
Stations on a ring are wired to one another in a circle around the entire network. It looks like a bus network except there are no termination points.
Data is passed around the ring and unlike a bus network, stations in a ring regenerate the signal before passing it along.
This makes the ring topology active, as opposed to the passive bus topology.
