A graphics card (also called a video card, display card, graphics adapter, VGA card/VGA, video adapter, display adapter, or colloquially GPU) is a computer expansion card that generates a feed of graphics output to a display device such as a monitor.
Graphics cards are sometimes called discrete or dedicated graphics cards to emphasize their distinction to integrated graphics processor on the motherboard or the CPU.
A graphics processing unit (GPU) that performs the necessary computations is the main component in a graphics card, but the acronym GPU is sometimes also used to refer to the graphics card as a whole.
