OK! Here is just one fragment.
" Type CGA, EGA, VGA, super VGA
Determines what resolutions are available and how many colors can be displayed. Type Stands for Resolution(s)
CGA Color Graphics Adapter 320 x 200
EGA Extended Graphics Adapter 640 x 350
VGA Video Graphics Adapter 640 x 480
SVGA Super VGA 800 x 600, 1024 x 768, or 1280 x 1024
New systems now come with super VGA with a picture size of 800 x 600 pixels (as a minimum) and 16 million colors
Color The number of colors displayed can vary from 16 to 256 to 64 thousand to 16.7 million. The more colors, the smoother graphics appear, especially photos.
The number of colors available actually depends more on the video card used and on how much memory is devoted to the display. It takes 8 bits to describe 1 pixel when using 256 colors. It takes 24 bits per pixel when using 16 million colors. So a LOT of memory is needed to get those millions of colors. Video cards now come with extra memory chips on them to help handle the load."
