Basic Infomation on video cards(Graphics cards)



A graphics card is the devise that allows you to see what’s on your screen. Without a graphics card your screen ( even if on and is working)won’t show any image. The graphics card is a very complex and powerful devise. The image you see on your screen is made up of tiny dots called pixels, most screens show millions of pixels other even more!

The graphics card works like this, the graphics card gets binary code which it translates to color, the graphics card then outputs those colors on your screen.

This is a very basic outline of how these devises work. If you would like more in-depth information on how this devise works please go to: http://en.wikipedia.org/wiki/Graphics_card
