Compared to the bus topology, a star network generally requires more cable, but a failure in any star network cable will only take down one computer's network access and not the entire LAN. (If the hub fails, however, the entire network also fails.) See the illustration of Star Network Topology.
Ethernet now commonly uses a star topology,although this is rather unfavorable when it comes to system wiring and canlead to excessive cabling effort or highly cascaded communication depend-encies.Another factor is that not all Ethernet installations are identical.
