Ideas/Strategies in the Sicilian?

I'm always hearing about an exchange sacrafice white is supposed to make on c3 (exclusively in dragon variations??), but no comprendo. Any good games y'all know of to demonstrate the point?

Also how would you characterize the basic stratgies each side has? I know that basically white tries to attack the kingside faster than black can expand on the queenside..but that is very basic and irrelevant.
