Artificial Intelligence –

By definition, Artificial Intelligence is a branch of computer science concerned with the study and creation of computer systems that exhibit some form of intelligence; systems that learn new concepts and tasks; systems that can reason and draw useful conclusions about the world around us; systems that can understand a natural language or perceive and comprehend a visual scene; and systems that perform other types of feats that usually require human intelligence. Humans are prone to making errors. It's how we learn, survive and evolve. "Necessity is the mother of all inventions", and how true this statement is. The main reason why the computer was invented is because humans took a lot of time to perform huge mathematical calculations!
