Graphics card
  • The graphics card is the part of the computer directly connected to the monitor. It sends a signal to the monitor to control what it displays.

  • Graphics cards nowadays commonly have dedicated processors for 3D graphics e.g. Games and CAD, and dedicated video RAM for large and complex images.

  • Laptop computers always have a graphics card integrated with the motherboard. Entry level desktop computers usually have a graphics card built-in to the motherboard also. In high-quality desktop computers the graphics card is often separate, and can therefore be updated.
