The ring topology is constructed from a closed loop cable, known as a ring, that each node on the network connects to. In this topology, the network forms a circular shape and data is transmitted clockwise via a token that each node in the network actively listens for. If a node does not want to transmit data, the node will act as a repeater and send the token around the ring. If a node does want to transmit data, it must wait until the token makes its way to the node and is no longer carrying data.
