video card
A video card (also called a video adapter, display card, graphics card, graphics board, display adapter, graphics adapter or frame buffer〔(【引用サイトリンク】title=Frame Buffer FAQ )〕) is an expansion card which generates a feed of output images to a display (such as a computer monitor). Frequently, these are advertised as discrete or dedicated graphics cards, emphasizing the distinction between these and integrated graphics. Within the industry, video cards are sometimes called graphics add-in-boards, abbreviated as AIBs, with the word "graphics" usually omitted.
== History ==
Standards such as MDA, CGA, HGC, Tandy, PGC, EGA, VGA, MCGA, 8514 or XGA were introduced from 1982 to 1990 and supported by a variety of hardware manufacturers.
Virtually all current video cards are built with either AMD-sourced or Nvidia-sourced graphics chips.〔 Most video cards offer various functions such as accelerated rendering of 3D scenes and 2D graphics, MPEG-2/MPEG-4 decoding, TV output, or the ability to connect multiple monitors (multi-monitor). Video cards also have sound card capabilities to output sound along with the video for connected TVs or monitors with integrated speakers.
