Most DSLRs use a sensor that is smaller than your traditional 35mm film frame. This is why if you take a 24mm lens and slap it on your camera with a smaller sensor, you have to multiple the focal length by 1.5 for most Nikons, and 1.6 for most Canons. Thus, the 24mm really is a 36mm. Full frame cameras have a sensor that is the same size as a 35mm frame. This results in higher quality photos and your 24mm stays a 24mm.
This is why an:
8MP p&s file has less information per file than a 8MP DSLR with a cropped sensor.
And why an 8MP DSLR has less information per file than an 8MP DSLR fullframe camera.
The sensor with the most surface area can take in the most information. You can have 8MP squeezed into a tiny sensor, or have 8MP for a large, fullframe sensor. Obviously the fullframe sensor, with the larger surface area, can take in and use much more information detail than the point and shoot with the same MP count.
This is why MP is such a marketing gimmick. Companies want you to believe your 10MP point and shoot camera has the same quality files as a big DSLR with 10MP. Truthfully, it couldn't be further from the truth.
