Detailed explanation-1: -Disconnecting a particular node in a star network will not disrupt service on the rest of the network, and the concentrator can easily locate a malfunctioning network node. If the concentrator fails, the entire network will be disabled. Some examples of star network include Ethernet switches and hubs.
Detailed explanation-2: -In a star network, a cable failure on a single spoke will only affect the spoke endpoint that it links to the central computer. All the other workstations will continue to function normally with the exception that they will not be able to communicate with the device that resides on the failed spoke.
Detailed explanation-3: -3 The primary disadvantage of the star topology is the hub is a single point of failure: If the hub were to fall short the whole network would fail as a result of the hub being connected to every computer on the network. There will be communication break down between the computers when the hub fails.
