a ring topology gives a closed loop transmission medium. repeater at each node connection repeat the signals. this is done to minimize any signal degradation.

traditional right have the same failure risk as buses, any break brings the entire network down. to prevent these failures, most right implementations such as token right are actually wired in a star topology with an out loop and a return loop from each workstation to the wiring hub.

there is not terminating resistor
4 or 16 Mbs
token ring
if you add a node, will need to reconfigure all the other nodes
heavy frequent load is good

look at the picture to see how a ring topology looks like
