Since the invention of computers or machines, their capability to perform various takes went on going exponentially. Humans have developed the power of computer systems in terms of their diverse working domain, the increasing speed and reducing size with respect to time. 

A branch of computer science named Artificial Intelligence pursues creating the computers or machines as intelligent as human beings. According to the father of Artificial Intelligence, John Mc Carthy, it is "The science and engineering of making intelligence machines, especially intelligent computer programs". Artificial Intelligence is a way of making a computer, a computer-controlled robot, or software think intelligently, in the similar manner the intelligent human think. Al is accomplished by studying how human brain thinks and how human learn, decide and work while trying to solve a problem, and then using the outcomes of this study as a basis of developing intelligent software and systems.
