Artificial intelligence (AI), the ability of a digital computer or computer-controlled robot to perform tasks generally associated with intelligent beings. The term is often applied to the project of developing systems endowed the intellectual processes characteristic of humans, just like the flexibility to reason, discover meaning, generalize, or learn from previous experience. Since the development of the digital computer in the 1940s, it has been practically exhibited that computers can be programmed to carry out a very complex task. For example, discovering proofs for mathematical theorems or enjoying chess with nice proficiency. Still, despite continued advances in PC process speed and memory capability, there square measure thus far no programs which will almost like human flexibility over wider domains or in tasks requiring much everyday knowledge. On the other hand, some programs have earned the capability levels of human consultants and professionals in playing sure specific tasks, in order that computer science during this restricted sense is found in applications as numerous as diagnosing, PC search engines, and voice or handwriting recognition.
