A free software is some computer code that can be used not having restriction by the initial users or by other people. This can be created by copying the program or adjusting it, and sharing it in various methods.

The software freedom 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 rights. He created a set of four freedoms for software to become considered free:

1 . The freedom to modify the software.
