Three categories of software

Software can be classified into many categories. Can you define all its categories? Of course you have been familiar with the term Shareware, Adware, Freeware, but sometimes when you’re downloading a software, it allows you to try it for 15 days only!  very annoying. Why this is happening? Yes, because you’re downloading Shareware software.

What about a software that embeds ads on it. You hate them as much you hate spam. I can imagine your  feeling, but you must accept it because you have installed an adware software into your computer. Below is the clear definition about those types of software:


You can download this software from the internet. The user is permitted to use the program for free, but for a limited period, commonly for fifteen days or thirty days. This is what we call a trial time. At the end of the trial period, you must purchase the software in order to use it, otherwise you should uninstall the software.

The justification of shareware is to give buyers the opportunity to use the program and assess its usefulness before purchasing a license for the full version.

The examples of shareware software are. Kaspersky Internet Security 2011, WinZIp, and TuneUp Utilities.



This type if software also can be downloaded from the internet. The good news is, it’s free of charge. Hence you can use it permanently without  any trial period and no need to spend a penny.

The author of the Freeware typically limited to one or more users' rights, including rights to copy, distribute, modify and create derivative works of the software or derive source code.

CCleaner, Recuva, and Defraggler are the Freeware software produced by Piriform company.



Adware or advertising supported software is any software that automatically plays, displays, or downloads advertisements to a computer. These ads may be in the form of a pop-up. User must view and cannot disable the ads as it violated the license agreement of the Adware.

The purpose of adware is to generate revenue for its author. Adware, by itself, is harmless, some adware may be bundled with spyware embedded as keyloggers and other invasive programs.

You can download these three types of software on Tucows, Filehippo, Cnet, Zdnet. Want to receive more info about software, subscribe to my feed or my newsletter.
