Star network

In a star network, every host is connected to a central hub.

In its simplest form, one central hub acts as a conduit to transmit messages.

The hub and hosts, and the transmission lines between them, form a graph with the topology of a star.

Data on a star network passes through the hub before continuing to its destination.

In a typical network the hub can be a network switch, ethernet hub, wireless access point or a router The star topology reduces the impact of a transmission line failure by independently connecting each host to the hub.
