Artificial intelligence, or AI, refers to software used by computers to mimic aspects of human intelligence.
Artificial intelligence is intelligence exhibited by machines. On the other hand, natural intelligence is the intelligence exhibited by humans and animals. The study and development of AI aims to simulate human functions and behavior. In computer science, the field of AI research defines itself as the study of "intelligent agents," any device that perceives its environment and takes actions that maximize its chance of success at some goal. Colloquially, the term "artificial intelligence" is applied when a machine mimics cognitive functions that humans associate with other human minds, such as learning and problem solving.
