Concept:Bus topology connects all devices to a single backbone cable, while star topology gives each device a separate cable to a central hub.Explanation:In a bus topology, all nodes share one main cable, so the total cable length needed is less.In a star topology, each device has its own cable connected to the central switch or hub, which increases cable usage.Less cable means lower material cost and simpler installation for a bus network.Thus, the advantage is that bus topology requires less cable length than star topology.The other options are not valid advantages of bus topology.Answer:D. It requires less cable length than star topology.
