Quantizers

Another novice (or newbie) question from me. I have this simple question and, thanks in advance, to the kind people who would answer it. Here goes:

1. What's a quantiser?
2. How does that number actually determine the compression of I frame,
P-frame, B-frame?
I mean what kind of mathematical equation is used to determine the filesize of the I frame , P frame, B frame?
(lower quantiser=good quality, higher quantiser=poor quality?)

Sorry if this is a repetition, but time constraints hamper me from searching this forum and using its full potential. If anyone can help me with references to other threads, thanks in advance, for that too.
