Normal maps have more depth than bump maps. But they are both flat when looked at from the edges. Displacement maps will nudge polygons if you have a high enough resolution of both the polygons and the displacement map image applied to them.
Some 3D apps will use bump and normal maps for displacing with. But displacement maps really do a better job of that.
I often sprinkle bumps on top of my displacements when texturing.
