A free software is some computer code that can be used not having restriction by the first users or perhaps by anyone else. This can be made by copying the program or enhancing it, and sharing that in various techniques.

The software flexibility 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 with their moral legal rights. He developed a set of 4 freedoms pertaining to software being considered free:

1 . The freedom to change the software.

This can be a most basic belonging to the freedoms, and it is the one that makes a free system useful to its users. It is also the liberty that allows a grouping of users to talk about their modified rendition with each other plus the community at large.

2 . The freedom to study the program and learn how it works, to enable them to make becomes it to slip their own applications.

This freedom is the one that a lot of people imagine when they listen to the word “free”. It is the flexibility to upgrade with the application, so that it will what you want this to do or perhaps stop undertaking anything you rarely like.

3 or more. The freedom to distribute clones of your revised versions to others, so that the community at large can usually benefit from your improvements.

It is the flexibility that allows a grouping of users (or person companies) to produce true value added versions within the software, that can serve the needs of a specific subset of this community.
