, ARTIFICIAL INTELLIGENCE
AI is a broad area of computer science that makes machines seem like they have human
intelligence. For example, it is not only when a computer is programmed to drive a car
by obeying traffic signals, but it is when that programme also learns to exhibit signs of
human like a road rage. The term AI was coined back in 1956 by Professor John
McCarthy. He tried to prove that machines could learn like a young child using trial and
error
