Video card

Alternatively referred to as a display adapter, graphics card, video adapter, video board, or a video controller, a video card is an internal circuit board that allows a display device such as a monitor to display images from the computer. Today's video cards are most commonly connected to the AGP, PCI, or PCIe expansion slot on the motherboard, however, can also be found on-board.
