Early binding  & late  Binding is a concept of OOPS..B'coz the data and the method
which will operate on data are sepertaely defined in oops(called abstraction
).And they will bind data members and methods either at the complie time or
runtime time. This is called encapsulation.

In early binding the data and method are binds at the complie time where as in
late binding the data and method will bind at the runtime.
