A word processing package allows you to use your computer to prepare all kinds of text. The keyboard in effect becomes a typewriter but there are some added advantages. A word processor stores the information electronically rather than directly onto paper. This means corrections, alterations, insertions and deletions can all be carried out before the document is printed. Different layouts can also be tried out on the screen. Standard letters can be keyed in once and stored. They are ready to be printed out as often as required. In fact, the output increases while the preparation time is greatly reduced.
