A company has a legacy network in which all devices receive all messages transmitted by...

ABus topologyis a network setup in which all devices share a single communication channel (central wire), and data is transmitted along this cable. Each device listens for data but only processes packets addressed to it. This topology was widely used in older Ethernet networks.

Star topologyuses a central switch or hub, not a shared wire.

Point-to-point topologyinvolves a direct link between two devices, not multiple devices sharing a medium.

Ring topologyconnects each device to two adjacent devices in a circular path, not a single shared bus.
