Detailed explanation-1: -On a star network, if one node fails, only that node is affected. The other nodes continue to operate normally. If the hub/switch fails, however, the entire network is inoperable until the device is repaired.

Detailed explanation-2: -Star Topology: This is one of the advantages of a star Topology as it is easy to isolate the faulty device and repair or replace it without affecting the entire network. However, if the central hub or switch fails, then the entire network will be affected, and communication between all devices will stop.

Detailed explanation-3: -Reliability. 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.

Detailed explanation-4: -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-5: -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.
