RAW is an image file format used in pro and prosumer digital cameras. It preserves much more information than compressed JPEG files, so it gives you a better final image. Working with RAW files, however, is a bit of a nightmare. If you're diving into the high end anytime soon, pick up PopSci contributor Mikkel Aaland's new book Photoshop CS2 RAW. Aaland is an old hand at making sense of overcomplicated photo software, and this tome is no exception: exhaustive, yet easy to follow. That's his very cute daughter on the cover.
