digital camera records the captured image by "light sensors" that see
everything in grayscale and no color even through the rgb filters. the
built-in processor and the built-in software will process and transform
these rgb gray tones (think of taking b&w through color filter) into digits.
this is minimal processing and its stage is in raw form or known as raw
format. many professionals like this format ( 12 to 14 bits of information)
to tweak for the best color quality output and save it in image formats such
as jpg, tif, bmp, png...etc. but experience and knowledge are crucial for
best result as it's manually manipulated. you could choose to let the camera
do the tweaking and that is automatic processing into jpg (8 bits of
information) or tif with some camera but basing on average programmed
mapping. it could be analogous to exposure metering techniques. it is not
necessary inferior to raw format but definitely not better (of course i'm
referring to those who know how to tweak the raw format).

What is RAW format exactly - and why should it be used on my camera,
if indeed it should?
RAW is just another format similar to all other format, except
- RAW has minimal processed by camera, and leave more room for you to
process further more
-JPEG is an already processed by camera (hardware) , so you don't need to
process again using software if you do not wish to process any further.
That's the general, and if you have the heart for RAW vs JPG war then just
hang around to enjoy the war <bg>
