Basically, composite mixes 3 pieces of information in one signal.

S-Video breaks the 3 pieces of info into 2 "components"

Component video breaks the 3 pieces of info into 3 "components"

So, you can think of each step up (each new component) providing more 
bandwidth, allowing for better picture quality.

See http://en.wikipedia.org/wiki/S-Video for more details.
