Artificial intelligence is intelligence exhibited by machines. 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.

The science of making computer do things that require intelligence when done by humans. Artificial intelligence is a branch of science which deals with helping machines find solutions to Complex problems in almost human like fashion.

This generally involves borrowing characteristic from human Intelligence, and applying them as algorithms in a computer friendly way. A more or less flexible or efficient approach can be taken depending on the requirements established, which influence how are artificial the intelligent behavior appears.”

Artificial intelligence is the study of how to make computers do things at which at the moment people are better. Its main aim is depends upon the situation to take the decision automatically. AI is a scientific research. It is a part of computer system that is concerned with designed, intelligent computer system that is system that exhibits the characteristic we associate with intelligence in human behavior.

AI is concerned with intelligent behavior in artefacts. Intelligent behavior in terms, involves perception, reasoning, learning, communicating and acting in complex environments.

AI has as one of its long term goals the development of machines that can do this things as well as human can, or possibly even better. Another goals of AI is to understand this kind of behavior whether it occurs in machines or in humans or other animals.

Artificial intelligence has many sub fields which involves neural networks, Evolutionary computation, expert system, Natural Language Processing, planning, Robotics, vision but they employee common techniques such as representation, learning, rules, search.
