As a common term, refers to intelligence as demonstrated by machines, versus natural intelligence displayed by humans or other biological entities. AI is still evolving as a discipline but is frequently referred to as any electronic or servo-mechanical device that perceives its environment and takes actions to maximize its chance of successfully achieving its goals and survival. The term artificial intelligence is also used to describe machines or computers that mimic cognitive functions that humans associate with tasks, such as learning and problem solving. In short, AI is software that learns.
