Abstraction is process in which you collect or gather relevant data and remove non-relevant data. (And if you have achieved abstraction, then encapsulation also achieved.)

In Hindi

" Abstraction ek process hai jisme aap relevant data ko collect or gather karte ho aur non-relevant data ko remove karte ho"

Encapsulation is a process in which you wrap of functions and members in a single unit. Means You are hiding the implementation detail. Means user can access by making object of class, he/she can't see detail.
