Explanation:
Detailed explanation-1: -Bus topology can be extended easily on either side. Disadvantages: Becomes slow with the increase in number of nodes. Only a single message can travel at a particular time.
Detailed explanation-2: -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-3: -Network operation depends on the functioning of the central hub. Hence, central hub failure leads to failure of the entire network. Also, the number of nodes that can be added, depends on the capacity of the central hub. The setup cost is quite high.
