to include data from an upper layer protocol in a lower 
layer protocol is called encapsulation 
abstraction is a mechanism and practice to reduce and 
factor out details so that one can focus on a few concepts 
at a time.

Encapsulation means we hide the data from directly 
interaction and Abstraction means 
we bother about what the object can do but don't bother 
about how it does?

Encapsulation means we are hiding the code and data in to a 
single unit to protect the data from outside world.

Abstraction means we know about the object how it can be 
used but we dont know how it is implemented. and we can 
hide the data using the AccessSpecifiers.

good day 
forum from namdev and shekhar

I am not sure if this helps....
By encapsulating data user creates an Abstract object.
This is achieved in C++ putting the data members as private 
and member functions as public.
The end user only know how to call the methods associated 
with the object.

Encapsulation is to hide the code complexities from outside
world where as Abstraction is to show only essential characters.

By Encapsulating the implementaion, the client can not see 
actual implementation classes. Cient can see only 
abstraction class, thru which (abstraction class) client 
can create the different objects.
Ex: Shape class is Abstraction class
    Circle class, Square class is encapsulated, but the 
client can create the circle, square shapes by abstraction 
class i.e Shape class.
Hope I have clarified the doubt.

Encapsulation is a process of binding data and methods into
a single unit. 

Abstraction is a process where by we identify important
aspects of phenomenon and ignoring its details.
