A star network is an implementation of a spoke–hub distribution paradigm in computer networks 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 star network is one of the most common computer network topologies 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 The hub manages and controls all functions of the network It also acts as a repeater for the data flow
