How does the concept of inheritance relate to component-based development?

What will be an ideal response?

With object-oriented technology the implementation of a class and or its interface can be inherited by another class. For example, if you write a Person class that calculates the age of the person from his or her birth date, then its subclass, Patient, would be able to do the same by simply inheriting the implementation of Person.
