graphics adaptor         
<hardware, graphics> (Or "graphics adapter", "graphics card", "video adaptor", etc.) A circuit board fitted to a computer, especially an IBM PC, containing the necessary {video memory} and other electronics to provide a bitmap display. Adaptors vary in the resolution (number of pixels) and number of colours they can display, and in the refresh rate they support. These parameters are also limited by the monitor to which the adaptor is connected. A number of such display standards, e.g. SVGA, have become common and different software requires or supports different sets. (1996-09-16)

Graphics card

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.

Most graphics cards are not limited to simple display output. The graphics processing unit can be used for additional processing, which reduces the load from the central processing unit. Additionally, computing platforms such as OpenCL and CUDA allow using graphics cards for general-purpose computing. Applications of general-purpose computing on graphics cards include AI training, cryptocurrency mining, and molecular simulation.

Usually, a graphics card comes in the form of a printed circuit board (expansion board) which are to be inserted into an expansion slot. Others may have dedicated enclosures, and they are connected to the computer via a docking station or a cable. These are known as external GPUs (eGPUs).

Graphics cards are often preferred over integrated graphics for increased performance.
