That is, although we use the freeware we can not violate the copyright on software, such as multiplication to others or use the software to other interests. Typically freeware is distributed without any code of the program concerned. And if we do not have to pay, what the purpose of the creator of the freeware? The goal clearly is to the campaign. Both the campaigns themselves (for the individual programmer) or products (for the developer kakap class). Other objectives that are possible to get input from users and some (although rarely found), which aims to break a system. Some examples of freeware is Paint.net, Rocket Dock, Ccleaner, and many more.

The second type is shareware. Shareware is software that can be used without charge in a period of time. After the period is completed, users are given the option, whether to continue using the software (with the consequences of pay) or no longer use the software.

The fourth type of start is the popular open-source software. Unlike the previous types of software, open source software gives us the freedom to use, in accordance with the changing needs, and medistribusikan return, both the original software and we have changed. Usually the software is open source code to include in the source of the distribution of funds. The goal of making open source software is usually not for commercial purpose, but more to the social goals of how the software can be a benefit for users.
