What is word processing?
Answers
Answer:
Word Processing refers to the act of using a computer to create, edit, save and print documents.
A word processor is a text editor that displays text as it will be printed, or as close to that as practical (commonly referred to as WYSIWYG: “What You See Is What You Get”). Modern word processor software also includes the ability to embed other objects like images in the text.
A word processor is distinguished from other textual composition tools:
a plain text editor, which displays text exactly as typed, as simply ASCII or Unicode characters with no particular form or format except lines.
a text formatter, which uses a plain text editor to insert markup language that is processed by a compiler or interpreter to create a printable or displayable document with formatting: fonts, margins, special characters not found on the keyboard, etc. Examples of text formatter input is the Unix troff (Typesetting Run-OFF) macro language, Rich Text Format (RTF), Donald Knuth’s TeX system, and the LaTeX front-end macro system for TeX, and the Postscript page description programming language.
a desktop publisher, which is similar to a word processor, with WYSIWYG user interface, but offers more text formatting features for page layout, with more emphasis on defining text or image “frames” as shapes to contain the material and placement on the page.
All of the above generally have the capability of taking either WYSIWYG input or markup-language input and transforming it into device-independent markup languages like HTML, RTF, or Postscript and its more universal output format, PDF (Portable Document Format)
