The disadvantage of this topology is that a problem with one node will crash the entire network.

Bus Topology

Explanation:

In local area networks (LANs), Bus topology is used to connect all the computers on the single cable. This cable is called backbone of the network. In this type of network when a computer sends data, it will be received on entire network.

For Example

In water line system, all the taps that are connected to single pipe. If the pipe or a single tap broken this will affect the whole system.

Entire system can be crash if any node or wire will break.
