Detailed explanation-1: -Due to the Uni-directional Ring, a data packet (token) must have to pass through all the nodes. If one workstation shuts down, it affects whole network or if a node goes down entire network goes down. It is slower in performance as compared to the bus topology.
Detailed explanation-2: -Sharing a single channel results in a slower access rate in a bus topology. In a ring topology, communication delay increases with the number of nodes in a network. In a bus topology, cabling cost is low as only a single cable is required to connect n nodes.
Detailed explanation-3: -A bus topology becomes slow by heavy network traffic with a lot of computer because networks do not coordinate with each other to reserve times to transmit. It is difficult to troubleshoot a bus because a cable break or loose connector will cause reflections and bring down the whole network.
