What happens if the switch fails in Star Mode?

In a Star Mode network topology, all devices are connected to a central switch. Therefore, if the switch fails, it disrupts the core functionality of the network. The central switch acts as a hub through which all data is sent and received. When it fails, the communication paths between all connected devices are interrupted, leading to the unavailability of connections across the network. This means that every device that relies on the switch for connectivity will be impacted, making all connections affected by the switch failure.

In contrast, if the switch were functioning normally, each device would be able to communicate with one another through the switch. However, without the switch's operation, there is no way for the devices to transmit or receive data, which is why the failure directly impacts all connections in a Star Mode configuration.
