A free software is a piece of computer code that can be used not having restriction by the first users or by anyone else. This can be made by copying the program or changing it, and sharing it in various methods.

He developed a set of 4 freedoms just for software for being considered free:

1 . The freedom to change the software.

This is the most basic in the freedoms, and it is the one that the free method useful to nearly all people. It is also the liberty that allows several users to talk about their modified version with each other and the community at large.

2 . The freedom to study this software and know the way it works, so that they can make becomes it to install their own needs.
