Step Into AI. What is Artificial Intelligence?

In simple terms the AI or the Artificial Intelligence means the replicating the Human Intelligence. In deeply the artificial intelligence is a large concept that spread through a huge domain. Actually I assume there is no domain when we come to the AI, because it spread in each and every domain that exists. So, the artificial intelligence is the theory and development of computer systems with the ability to perform tasks normally requiring human intelligence, such as visual perception, speech recognition, decision making and translation between languages. Also there are another two concepts that goes with AI very closely.
