video card - otherwise called a graphics card, graphics adapter or video adapter.

1. The video card - otherwise called a graphics card, graphics adapter or video adapter - processes and renders the graphics output from the computer to the computer display
2. Many video cards offer added functions, such as accelerated rendering of 3D scenes and 2D graphics, video capture, TV-tuner adapter, MPEG-2/MPEG-4 decoding, FireWire, light pen, TV output, or the ability to connect multiple monitors 
3. Video hardware can be integrated on the motherboard. However limitation to this integrated graphics chip often only occurs with early machines 
4.  A dedicated Graphics Card on the other hand has its own RAM and Processor specifically for processing video images, and thus offloads this work from the CPU and system RAM 
5. he video BIOS or firmware contains the basic program, which is usually hidden, that governs the video card's operations and provides the instructions that allow the computer and software to interact with the card. 
6. The RAMDAC, or Random Access Memory Digital-to-Analog Converter, converts digital signals to analog signals for use by a computer display that uses analog inputs such as CRT displays
   A GPU is a dedicated processor optimized for accelerating graphics. 
7. The processor is designed specifically to perform floating-point calculations, which are fundamental to 3D graphics rendering.
8. Digital-based standard designed for displays such as flat-panel displays (LCDs, plasma screens, wide high-definition television displays) and video projectors.
9. Video cards may use a lot of electricity, which is converted into heat. If the heat isn't dissipated, the video card could overheat and be damaged.
10. An advanced digital audio/video interconnect released in 2003 and is commonly used to connect game consoles and DVD players to a display.
