Default PCM, BCM xCM?

Hi,
I have a general question about onboard computers. What'* the difference between the PCM and BCM? are there any other CM'*? How about the ABS-CM?

Could someone list these parts, their locations and what they do?

Thanks,
Mark

Default

PCM - PowerTrain Control Module. This control module monitors, and controls engine & transmission parameters. It receives many various inputs. It also outputs signals & drivers to control engine/transmission performance.

BCM- Body Control Module. This control module monitors, and controls functions associated with the body.

ABS-CM - This sounds like the control module for ABS
