What's the difference between abstraction and encapsulation?

Question

In interviews I have been asked to explain the difference between abstraction and encapsulation. My answer has been along the lines of

• Abstraction<

Answer 1

Abstraction: In case of an hardware abstraction layer, you have simple interfaces to trigger the hardware (e.g. turn enginge left/right) without knowing the hardware details behind. So hiding the complexity of the system. It's a simplified view of the real world.

Encapsulation: Hiding of object internals. The object is an abstraction of the real world. But the details of this object (like data structures...) can be hidden via encapsulation.
