Actually, that's not quite true. All electronic images are composed of pixels. The higher the resolution, the smaller the individual pixels. What happens if you expand a photo far enough is that you see the individual pixels. Some programs will try to smooth the transitions between pixels, so you see fuzzy edges instead of a mosaic of little squares.

You can't create more information than was in the image you started with. It's easy to decrease resolution, i.e., combine pixels, but kind of hard to guess where the edges are when you try to make more pixels than you started with.

There's some pretty sophisticated impage enhancement software out there, but I for one am not will to pay for something like that....
