ClearType
ClearType, introduced by Bill Gates at Comdex in Las Vegas
in autumn 1998, is designed to dramatically improve the
readability of text on all screen types, including simple
screens. ClearType does not only use whole pixels for
display, but also uses invisible subpixels when calculating the
display of the screen contents. This technology can be used
on desktop computers and PDAs (personal digital assistants)
or electronic books. Dick Brass, vice president of Technology
Development at Microsoft, claimed that ClearType makes
economical screens look like expensive ones, and makes
expensive screens look like paper.
Clipboard
A special area in the main memory that is used by programs
and operating systems like Windows to temporarily store
information so that it can be copied or moved to other
documents.

Color depth
The amount of information used to describe the color of a
pixel. One bit can only have one of two states, on or off (1 or
0). Expressed in colors, this is either black or white. An 8-bit
color depth allows 256 colors. At least eight bits per color are
required for high-quality images. In 24-bit color, three color
channels are used (for example red, green and blue), meaning
3 x 8 bits or 256 x 256 x 256, for a total of 16.7 million
colors.
