A free software is a piece of computer code that can be used with no restriction by the first users or perhaps by anybody else. This can be made by copying this software or changing it, and sharing it in various methods.
The software independence movement was started in the 1980s by simply Richard Stallman, who was concerned that proprietary (nonfree) software constituted a form of oppression for its users and a violation of their moral privileges. He formulated a set of several freedoms for the purpose of software being considered free:
1 ) The freedom to improve the software.
