A free software is a bit of computer code that can be used while not restriction simply by the original users or perhaps by anyone else. This can be done by copying the program or modifying it, and sharing it in various ways.
The software independence movement was started in the 1980s by Richard Stallman, who was concerned that proprietary (nonfree) software constituted a form of oppression for its users and a violation with their moral legal rights. He created a set of 4 freedoms to get software to become considered free:
1 ) The freedom to alter the software.
This is actually the most basic for the freedoms, and it is the one that makes a free application useful to nearly all people. It is also the liberty that allows a team of users to talk about their modified variation with each other as well as the community at large.
2 . The freedom to study this program and understand how it works, in order to make becomes it to install their own reasons.
