Abstraction
Abstraction is closely related to encapsulation, and, to some extent, it overlaps with it. Briefly, abstraction provides a mechanism that exposes what an object does and hides how the object does what it's supposed to do.

The data is exposed on the car's dashboard, and the behavior is represented by the controls we can use to drive a car.
