Disadvantages of Star Topologies :-
On the flip side, if the hub fails in a star topology, the entire network comes down, so we still have central point of failure. But this is a much easier problem to troubleshoot than trying to find a cable break with a bus topology. Another disadvantage of a star topology is cost. To connect each workstation to the network, you will need to ensure that there is a hub with an available ports, and you will need to ensure you have a cable to go from the workstation to the hub.
Today, the cost is increasingly less of a disadvantage because of the low prices of devices such as hubs and switches.
