Artificial intelligence is really a good topic. Even if we are using it in day to day life. If you have more knowledge on this topic then kindly share here. It will be more interesting.
Right now it's nothing more than a dream. A computer is artificially intelligent if it can pass the Turing test - if you communicate with something and can't tell whether it's a person or a computer, and it's a computer, you're communicating with artificial intelligence. The term is improperly used for a lot of things, though - neural networks, expert systems, even programs like Eliza, which is a bout as close to AI as a snail is to a space shuttle.
