RGB: "Red, Green, and Blue" merely refers to a system for representing the
colors to be used on a computer display. Red, green, and blue can be
combined in various proportions to obtain any color in the visible spectrum.
Levels of R, G, and B can each range from 0 to 100 percent of full
intensity. Each level is represented by the range of decimal numbers from 0
to 255 (256 levels for each color), equivalent to the range of binary
numbers from 00000000 to 11111111, or hexadecimal 00 to FF. The total number
of available colors is 256 x 256 x 256, or 16,777,216 possible colors.
VGA: Abbreviation of "Video Graphics Array", a graphics display system for
PCs developed by IBM. VGA has become one of the de facto standards for PCs.
In text mode, VGA systems provide a resolution of 720 by 400 pixels. In
graphics mode, the resolution is either 640 by 480 (with 16 colors) or 320
by 200 (with 256 colors). The total palette of colors is 262,144.
Unlike earlier graphics standards for PCs -- MDA, CGA, and EGA -- VGA uses
analog signals rather than digital signals. Consequently, a monitor designed
for one of the older standards will not be able to use VGA.
Since its introduction in 1987, several other standards have been developed
that offer greater resolution and more colors (see SVGA , 8514/A graphics
standard, and XGA), but VGA remains the lowest common denominator. All PCs
made today support VGA, and possibly some other more advanced standard.
