History and definitions of Artificial intelligence: In the 1950s, scientist, and researchers came up with the idea to create machines which can think, learn and solve problems like humans. Alan Turing, a British scientist was one of them. Scientists and researchers started to create a machine which can play chess, solve mathematical problems and understand the natural language. Over the years, by 2000, scientists developed various techniques and technologies for AI systems like Machine learning, Deep learning, Natural language processing, Big data, etc. Artificial Intelligence (AI) systems  use algorithms and a large amount of data to recognize patterns, make decisions. It is a continuous process  to improve the performance of the system. Artificial Intelligence refers to the simulation of human intelligence in machines that are programmed to think, understand, learn and act  like humans or faster than humans. Various technologies like Machine learning, Natural language
