Information about fonts?

A font consists of a set of glyphs (images) representing the characters from a particular character set in a particular typeface. In professional typography the term typeface is not interchangeable with the word font, which is defined as a given alphabet and its associated characters in a single point size. For example, 8-point Caslon is one font, and 10-point Caslon is another. Historically, fonts came in specific sizes determining the size of characters, and in quantities of sorts or number of each letter provided. The design of characters in a font took into account all these factors.
