What is dynamic binding, Programming Languages

Dynamic Binding: - Binding refers to the linking of a procedure call to the code to be executed in response to the call. Dynamic binding (late binding) means that the code associated with a given procedure call is not known until the time of the call at run-time. E.g. Consider the procedure "Area" by inheritance, every object will have this procedure. Its algorithm is, however, unique to each object and so the area procedure will be redefined in each class that defines the object. At run-time, the code matching the object under current reference will be called.
