Answer : In Star Topology, each node (computer , printer, etc.) is connected directly by a hub or switch. Data transmitted over a network goes through a hub on its way to a specific device. As a result, less time is required to exchange signals. With a hub or a switch, it is easy to detect problems at the corners of the centrally controlled Star Topalji network. However, when using the hub, the signal is broadcast, that is, the signal goes to all the computers connected to the hub. But when using the switch, the signal only goes to the target computer. Although different types of cables can be used in Star Topalji, there is an excess of twisted pair cables.
