A set of glyphs (images) representing the characters from some particular character set in a particular size and typeface. The image of each character may be encoded either as a bitmap (in a bitmap font) or by a higher-level description in terms of lines and areas (an outline font).
There are several different computer representations for fonts, the most widely known are Adobe Systems, Inc.'s PostScript font definitions and Apple's TrueType. Window systems can display different fonts on the screen and print them.
