Editing Star network (section)

==Network==
The hub and hosts, and the transmission lines between them, form a [[graph (discrete mathematics)|graph]] with the [[star (graph theory)|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. In a typical network the hub can be a [[network switch]], [[Ethernet hub]], [[wireless access point]] or a [[router (computing)|router]] 

The star topology reduces the impact of a transmission line failure by independently connecting each host to the hub. Each host may thus communicate with all others by transmitting to, and receiving from, the hub. The failure of a transmission line linking any host to the hub will result in the isolation of that host from all others, but the rest of the network will be unaffected.<ref>{{cite web|url=http://searchnetworking.techtarget.com/dictionary/definition/what-is-star-network.html# |title=Star Network |publisher=TechTarget |access-date=2014-06-24}}</ref>

The star configuration is commonly used with [[twisted pair cable]] and [[optical fiber]] cable. However, it can also be used with [[coaxial cable]] as in, for example, a [[video router]].
