In the real world we'd have to build objects from other objects. For example you have a car, but a car encapsulates other objects, in essence we have a hierarchy of objects to make a car object. When you group... four wheel objects, an engine object, panel objects, dashboard, seats and so forth you end up with a car object. This is in-essence is an object hierarchy where multiple objects are grouped together to make another object.

Likewise your computer can consist of many objects. This could include the track pad, screen, keyboard and motherboard; also on the mother board there’s a CPU, SPU and GPU. So as with the real world of objects in our program’s can have objects inside of objects and keep going in that fashion to replicate the real world.
