The logical topology defines how the devices how the devices communicate across the physical topology.     A network wired in star topology can behave logically as a bus network by using a bus protocol and              appropriate physical switching Switch vs Hub: The switch sets up 'access tables' isolate each node's connection. This provides security for each node. The hub however sends every piece of traffic to every node on the network, meaning it is mid and not secure.
