Whatever we see on the monitor screen be it images or windows, these are made up of tiny dots called pixels. These pixels are translated into graphics by the computer itself and this is performed by the Graphics card. Graphics card control and enhance how the graphics are displayed on the screen. These are a very important computer component of a computer system. If the graphic card does not work properly, your screen might show wrong colors or show nothing at all because the entire display completely depends on the graphics card.
Computer is basically a company with its own art department. When an artwork is required, request is sent to the graphics department. Similarly, it is the graphics card that decides how to use the pixels on the screen. Creating an image out of binary data can be a little technical process which is only handled by the graphics card of the computer. If the graphics card stops working, it needs to be replaced immediately because no function can be performed without a graphic card.
