The graphics components are the part of your computer that control and enhance how graphics (pictures, videos, programs, animation, 3D) are displayed on your computer screen. Often, the graphics components are on a separate card that plugs into a slot on the motherboard, which is the main part of the computer. The images you see on yourmonitor are made of tiny dots called pixels. At most common resolution settings, a screen displays over a million pixels, and the computer has to decide what to do with every one in order to create an image. To do this, it needs a translator -- something to take binary data from the CPU and turn it into a picture you can see. Unless a computer has graphics capability built into themotherboard, that translation takes place on the graphics card.
