Detailed explanation-1: -Working traffic from node A to node B is carried clockwise along the ring, and working traffic from B to A is also carried clockwise, on a different set of links in the ring. A bidirectional ring carries working traffic in both directions.
Detailed explanation-2: -Bi-directional Ring Topology Data can travel in both the directions clockwise and anti-clockwise. This has an advantage over uni-directional ring topology, in case of a device failure, it can send data using other direction to still maintain the connectivity.
Detailed explanation-3: -Unidirectional Ring: In a unidirectional ring network, the data flows in only one direction either clockwise or anti-clockwise and such a network is called a half-duplex network. In general, most of the ring network allows this kind of data flow only.
