Word processor

A word processor (WP)[1][2] is a device or computer program that provides for input, editing, formatting, and output of text, often with some additional features.

WordStar, released 1978
WordPerfect, first released for minicomputers in 1979 and later ported to microcomputers
LibreOffice Writer, one of the most popular free and open-source word processors

Early word processors were stand-alone devices dedicated to the function, but current word processors are word processor programs running on general purpose computers.

The functions of a word processor program fall somewhere between those of a simple text editor and a fully functioned desktop publishing program. However, the distinctions between these three have changed over time and were unclear after 2010.[3][4]
