CNET GLOSSARY: Terms for the techie
Some software manufacturers release demonstration versions of their commercial programs for free. Often available for download at the manufacturer's Web site, demos give you the flavor of the real full-blown application but with some sort of limitation: perhaps the juiciest features are disabled, or you can't save anything you create, or the demo is a full working copy that simply expires after a certain number of days (the latter is commonly referred to as an evaluation version).
