Detailed explanation-1: -One of the main advantage of bus topology is that it is simple and inexpensive to implement, as only a single cable is needed to connect all devices. The main disadvantage is that if the bus cable fails, the entire network goes down.
Detailed explanation-2: -One of the benefits of bus networks is the ease of connecting devices onto the network, which generally requires less cabling than a star topology, for instance. Also, failure of a node does not impact the rest of the network. On the downside, a network cable failure shuts down the entire network.
Detailed explanation-3: -Some important features of ring topology: Since only one device has a network charge, and only two devices are allowed to communicate simultaneously, the use of tokens prohibits the chance of collisions or cross-communication in it.
Detailed explanation-4: -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.
