What is Artificial Intelligence and How its work?

Artificial Intelligence ( AI) is a vast branch of computer science that deals with the development of smart machines capable of executing tasks that usually require human intelligence. AI is an interdisciplinary science with different approaches, but in nearly every field of the education field, software industry, developments in machine learning and deep learning are causing a paradigm change.
