Detailed explanation-1: -In star topology, the central site plays an important role; if it fails, all the connections will go down. Performance of the central hub dictates the performance of the connection. For a star topology, it may happen that two nodes might be closed to each other; however, they will have to communicate via central node.
Detailed explanation-2: -Disadvantages. Though star topologies may be relatively safe from failure, if the central switch goes down then the entire network will go down.
Detailed explanation-3: -In a star network, the switch or hub is a central point of failure. If this component fails, none of the connected devices will be able to communicate or access network resources. However, a failure of any of the individual cables or workstations will not affect the network.
