When we prepare a system who can perform all human activities are called artificial intelligence or we can say when a computer is programmed in such a way, so that it can perform all human tasks are called artificial intelligence. Intelligence power in human beings comes by thinking, seeing, touching & learning by previous experiences and intelligence in computer systems is developed through which Robotic system or computer system is prepared.

Artificial intelligence is called as our future but if we observe AI is our present because already we have started using AI Application in our daily routine for our convenience. For example Siri, Alexa Device, Google map, Google assistance etc. are the best examples of Artificial Intelligence. In this research paper we will discuss in detail about AI its types and real life application which is currently in use
