Types of software that are downloaded from the Internet

Generally, there are four major types of software you can download from the Internet. These are Demoware, Freeware, Shareware and patches/upgrades.

Demoware - This is a minor version of a retail copy of software. By minor, we mean that in some way the functionality of the program has been reduced enough to make the program marginally useful. The primary purpose of Demoware is to let you "test drive" software before making a decision to purchase it.

Freeware - Freeware is free, no strings attached. Usually these types of programs have been written by government agencies or companies that want you to use their programs and perhaps be induced into buying something from their main product line.

Shareware - Typically shareware products are a mix of freeware and demoware. In many cases, today you can get a fully functional program which is shareware, but has a built-in self destruct mechanism causing it to become unusable after so many days of use. Many shareware authors rely on the honor system for people to pay them.

Patches/Upgrades - Patches and Upgrades are not usually complete programs. Basically a patch or upgrade requires that you already have a particular piece of software on your computer. The patch will alter the software, either correcting a mistake in the system, or adding additional functionality to the software.
