After reading a little on Normal Mapping, I've come across a lot of different terms, such as Displacement maps.

I think I've got an idea of how normal maps basically works, but how about displacement maps? From what I've figured out, it seems like it does kinda the same thing as a bump or normal map, but I figure there has to be some kind of difference... Could someone please try to explain a little about the differences between these, and maybe some of the other maps I've missed?
