A free software is some computer code that can be used devoid of restriction by the initial users or by anyone else. This can be done by copying this software or adjusting it, and sharing that in various ways.
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 of their moral privileges. He formulated a set of several freedoms intended for software for being considered free:
1 . The freedom to improve the software.
It is a most basic from the freedoms, and it is the one that the free program useful to nearly all people. It is also the freedom that allows a team of users to talk about their modified release with each other as well as the community in particular.
2 . The freedom to study the program and know the way it works, so that they can make becomes it to slip their own needs.

It is the flexibility to upgrade with the application, so that it may what you want that to do or stop undertaking a thing you would not like.
5. The freedom to distribute clones of your changed versions to others, so that the community at large can usually benefit from your improvements.
This freedom is the most important within the freedoms, and it is the freedom which enables a free plan useful to the original users and to anybody. It is the liberty that allows a group of users (or specific companies) to produce true value-added versions from the software, which will serve the needs of a specific subset for the community.
