What is normal or surface normal?

Normal is surface angles, how it reacts with the light and affect the shading of the surface. A face could have different angles on different points. These angles can be represented as a line protruding in a perpendicular direction from the surface.

What is a bump map?

A bump map is a grayscale image to create a fake depth detail/bumpiness instead of just a 2D flat material.

White means the material will look more pulled up, black means more pulled down, thus creating a bumpy surface in accordance to the map. 

What is a normal map

A normal map is almost the same with a bump map, except it's purplish and uses RGB as X,Y,Z axis. It changes how the light react with the surface normal, without actually changing the shape of the mesh.

What is displacement map?

A displacement map changes the mesh itself.
