Layer 2 switches is an aggregate of bridge, the bridge to forward of other communication frames, then different segments of the PC at the ends of the bridge is said can carry out data communication,
The points belong to different segments of the PC. A, B, A link to A layer 2 switches can communicate?
If the can communication, then switched to layer 3 switches, so A, B can communication? If PCA broadcasting in layer 2 switches on the PCB is a broadcast domain, if from the perspective of three layers, PCB does not belong to a broadcast domain, then PCA radio PCB can receive?

Switch is a multiport bridge, bridge, you can do is to switch can do,
