Artificial Intelligence (AI) is a term that refers to the use of computers to make decisions.
Artificial intelligence, in general, is the area concerned with creating strategies that enable computers to function in a way that seems intelligent, similar to how a person might.
The goals range from the rudimentary, where a program seems "a little wiser" than one would anticipate, to the more ambitious, where the goal is to create a fully aware, intelligent, computer-based being.
As software and hardware improves, the lower end is gradually fading into the background of ordinary computing.
