Detailed explanation-1: -If the bus fails, the network will fail. A limited number of nodes can connect to the bus due to limited bus length. Security issues and risks are more as messages are broadcasted to all nodes. Congestion and traffic on the bus as it is the only source of communication.
Detailed explanation-2: -Limited Cable Length − The central cable, or bus, in a bus topology has a limited length. If the cable becomes too long, it can cause signal loss and data errors. This means that bus topology is not suitable for large networks.
Detailed explanation-3: -If one node fails along the bus, it does not bring down the entire network. However, if a line break occurs on the network, the entire network will go down. Bus network lines have a limited physical distance and a limited number of allowed nodes before system usability decreases significantly.
Detailed explanation-4: -If the cable is damaged, the entire network will fail or be split. Difficult to troubleshoot problems. Very slow and not ideal for larger networks. Requires terminators at both ends of the cable to prevent bouncing signals that cause interference. More items
