Word processor

A word processor is a program used to create and print (chiefly textual) documents that might otherwise be prepared on a typewriter. The key advantage of word processor is its ability to make changes easily, such as correcting spelling, changing margins, or adding, deleting, and relocating entire blocks of text. Once created, the document can be printed quickly and accurately and saved for later modifications. Today most popular word processors offer a much greater range of facilities than the first such programs.

History
The first word processor for the Macintosh platform in 1984 was MacWrite, soon followed by Microsoft Word. Apple presently markets Pages as a word processor and desktop publishing application.
