What is Graphics Card?

   Its just a printed circuit board, that can be controls the output of the display screen.

       The Graphics is a part of your computer that can be control and enhance the Graphics properties (Pictures, videos, Programs, Animations, 3D)that are displayed on the computer screen. This can be mainly used for High Definition (HD) programming purposes.

INTEGRATED:

      In this type, the graphics can be in-built into the mother board. There are no add-in card can be used in these type of mother board. This can be mainly used for the Standard Computer's and Laptop's. It cannot be upgraded easily.

DISCRETE:

       In this type, there is no in-built graphics into the mother board. This is a Seperate Graphics board that can be add-in to the motherboard.  This board are in different sizes. They are 1GB, 2GB, etc,. In highest sizes, they will give a better performace. This type of graphics are easily  upgradable.

GPU:
