Detailed explanation-1: -if there is a problem with the main bus cable, the entire network stops working. as all computers on the bus can see all data that is transmitted, it is not classed as a secure network and can easily be hacked. data collisions are more likely, which causes the network to slow down.
Detailed explanation-2: -1. Include difficult reconnection and fault isolation, fault or break in the bus cable stops all transmission, even between devices on the same side of the problem. The damaged area reflects signals back in the direction of origin, creating noise in both directions.
Detailed explanation-3: -The bus topology doesn’t affect the whole network when one computer fails, only the whole network fails when the backbone failure affects. The main disadvantage of bus topology is that they are not easy to troubleshoot, identifying the problem is also difficult.
