basically it takes the place of a speedometer cable that older cars have, but it also reports important information to the computer and some other systems
The PCM gets it's signal from the ABS wheel speed sensors. (actually probably from both, but it definitely uses the wheel sensors for calculations) The latter two do get their signal from the VSS.
