Word ProcessingA word processor is a program used to type documents. Documents can be saved, closed and the opened again to continue working on them.
The keyboard of a word processor is similar to that of a typewriter, but its capabilities extend far beyond the typewriter's. For example, you don't have to press the Return or Enter key at the end of every line - in word processing, the line "wraps around" when it reaches the margin you've set and allows you to continue typing without stopping, you only press Enter (or Return) when you want to start a new paragraph or insert blank lines. If you make a mistake while typing use backspace or delete to erase it.
There are many commercial word processing programs including Open Office Writer , Microsoft Word , Corel WordPerfect and others. Windows comes with WordPad to edit and format documents and NotePad to edit text. Mac OS X comes with TextEdit or SimpleText in previous version. Open Office is an Open Source office application that can be downloaded for free at openoffice.org.
