Important Terms Related to Computer Programming

• Inheritance:: Inheriting features from a parent is known as inheritance. In programming language inheritance can be defined as the concept when a class of objects is defined, any subclass when defined can inherit one or more classes or objects.

• Encapsulation:: Data Encapsulation is a important concept of Object oriented programming of data hiding. It binds together the data and functions that manipulate the data and that keep both safe from outside interference and use.

• Abstraction:: Through the process of abstraction, a programmer hides all but the relevant data about an object in order to reduce complexity and increase efficiency.

• Polymorphism is the ability of an object to take on many forms. The most common use of polymorphism in OOP occurs when a parent class reference is used to refer to a child class object. For example a class of closed figure can include a triangle, rectangle, pentagon, hexagon, square etc. All these figures are defined under a class of closed figures. This is polymorphism

• Derived Class: A class which is created based on previous class. The derived class inherits the properties of the base class. It is also known as derived type.
