In Star topology all computers are connected using a central device known as hub. Star networks are one of the most general computer network topologies. In its simplest way, a star network consists of one main hub, switch or computer, which performs as a conduit to transmit packets. This consists of a central node, to which all other packets are connected; this main node gives a common connection point for all devices through a hub. In Star topology each node is transferred to central device known switch or hub. The switch is the server and the peripherals are the users.
