Question :

What is abstraction? How is encapsulation related to it?

Abstraction is a principle of Object Oriented Programming (OOP) that hide certain details and only show the essential features of the object.

Encapsulation is also frequently confused with abstraction, since the two concepts are closely related. Abstraction is a process of hiding the complexity and giving a simple interface. Encapsulation on the other hand is the mechanism by which the abstraction is implemented.
