Productivity programs are programs that help you perform tasks at home or at work. They can come installed as an Office suite of programs containing several individual programs or they can be installed separately. For example, Open Office is a suite of productivity programs containing a word processor (Write), spreadsheet, (Calc), presentation program (Impress), and a database program (Base) as well as a few others. An example of a stand alone productivity program is the word processor AbiWord.
