Detailed explanation-1: -Here are the cons/drawbacks of bus topology: In case if the common cable fails, then the entire system will crash down.
Detailed explanation-2: -A failure of the main bus cable will bring the whole network to a stop. However, if there is a break or failure in the cable that connects a single device to the bus, it will affect just this device; the rest of the network will carry on working.
Detailed explanation-3: -if the main cable fails or gets damaged the whole network will fail. as more workstations are connected the performance of the network will become slower because of data collisions. every workstation on the network “sees” all of the data on the network – this is a security risk.
Detailed explanation-4: -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.
Detailed explanation-5: -As a result, bus and ring topologies have difficulties, such as the possibility of the entire network being deactivated if one connection fails. Hence the correct answer is Bus and Ring Topology.
