3. Also
known as Video display Adapters.
Is a board that plugs into the computer to
give it display capabilities.
The display capabilities of a
computer, depends on:
the logical circuitry (provided in the video
adapter) and
the display monitor.

8. Intel: develop IGPs (integrated graphics
processors)
AMD (acquired ATI) develop GPUs
Nvidia also develop GPUs
Different manufacturers take GPUs and other
components to assemble video cards; thus
creating slight variations of video cards with
same GPUs
Video cards are marketed with GPU
manufacturer’s brand name
Most popular video brands are the Radeon of ATI
and GeForce of Nvidia
9. Determined
by the intensity of three
beams of light (Red, Green and Blue) and
the amount of information stored about a
pixel
Different
Modes
8 Bit – 256 Color Mode
16 Bit – High Color mode
24 Bit – True Color Mode
10. Bit Depth : The number of bits used to describe a
pixel is known as its bit depth.
Example:
24bit – Bit Depth means
8 bits for each Primary color,
around 17 Million Color Combinations,
around 10,000,000 discernible Colors
Thus offers True Color System

– both PC and console
Design/Drafting
Special effects creation/editing
Medical Instruments
And other purposes where fast rendering and
high resolutions are needed
