Define word processor

A type of editor whose prime plan is to produce tidily printed text, such programs use lots of added information (apart from actual text) to control the output on the printer. An end result of this latter fact is that files produced with one word processor cannot be read by design by another unless they are first transformed to ASCII text (with the loss of formatting information). Another, which saves the formatting, is to store up files in the Rich Text Format (RTF) or Hypertext Markup Language (HTML) format.
