AI refers to the simulation of human brain functions by machines. This is achieved by creating an ANN that can show human intelligence. The primary human functions that an AI machine performs include logical reasoning, learning, and self-correction. This is a very complex field, and to make machines that are inherently not smart think and act like humans requires lot of computing power and data feeds.

AI is classified into two parts:

• General AI: Making machines smart in wide areas, similar to humans in thinking and reasoning. This has still not been achieved today and many ongoing research activities have already been initiated.
• Narrow AI: Making machines smart in specific areas, such as digit recognition and playing chess. This is possible today.
