The Four Liberties of Free Software

A free software is some computer code that can be used with no restriction by the first users or perhaps by someone else. This can be created by copying the program or altering 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 of their moral rights. He created a set of 4 freedoms designed for software to be considered free:

1 . The freedom to improve the software.

This can be a most basic on the freedoms, and it is the one that the free software useful to its users. It is also the liberty that allows a group of users to share their modified release with each other plus the community at large.

2 . The freedom to study this program and know how it works, to enable them to make changes to it to slip their own requirements.

This independence is the one that most of the people think about when they listen to the word “free”. It is the liberty to upgrade with the system, so that it really does what you want this to do or perhaps stop doing some thing you would not like.

5. The freedom to distribute replications of your changed versions in front of large audiences, so that the community at large can benefit from your improvements.

This freedom is the most important of the freedoms, and it is the freedom which makes a free application useful to it is original users and to someone else. It is the independence that allows a team of users (or specific companies) to produce true value added versions within the software, which can serve the needs of a particular subset with the community.
