The word "artificial" has several meanings, but in general it refers to something that is not natural or man-made. It can describe something that is created or produced by humans, rather than occurring naturally. For example, artificial intelligence is a type of computer-generated intelligence that simulates human thought and behavior. Artificial light is also known as artificial or electric light, which refers to any form of lighting that is generated by an artificial source, such as electric bulbs or LEDs.
