IBM Monochrome Display Adapter
The Monochrome Display Adapter is IBM's standard video display card and computer display standard for the IBM PC introduced in 1981. The MDA does not have any pixel-addressable graphics modes, only a single monochrome text mode which can display 80 columns by 25 lines of high-resolution text characters or symbols useful for drawing forms.

A graphics card 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 an integrated graphics processor on the motherboard or the central processing unit (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 erroneously refer to the graphics card as a whole.

The large, tilted silver object is the GPU die, which is surrounded by RAM chips, which are covered in extruded aluminum heatsinks. Power delivery circuitry is mounted next to the RAM, near the right side of the card.
