"Power of 2" means the numbers 2, 4, 8, 16, 32, 64, 128, 256, 512, etc. Also called pow2 or n2.
Usually this is used to describe the Texture sizes that a game engine requires in order to make good use of video Memory. An example pow2 texture size would be 32x64.
A texture that is not powers of 2, like 33x24, is either padded up to the next pow2 size (probably wasting video memory) or else the game engine stops with an error message telling you it needs to be fixed.
