Data and information hiding are a broader notions, found in computer science & software engineering. It refers to the fact that those part of a computer program that may change must not be accessible from other modules/from clients.

Encapsulation is a term that is found in Object-Oriented paradigm and refers to keeping the data in private fields and modify it only through methods.

Thus encapsulation may be seen as a way of achieving data hiding in object-oriented systems.
