A free software is a computer code that can be used not having restriction by simply the first users or perhaps by other people. This can be done by copying this software or modifying it, and sharing it in various methods.

The software independence 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 legal rights. He developed a set of several freedoms for the purpose of software for being considered free:

1 . The freedom to switch the software.

This is the most basic of this freedoms, and it is the one that makes a free method useful to nearly all people. It is also the liberty that allows a team of users to talk about their modified version with each other plus the community in particular.

2 . The freedom to study this software and learn how it works, so that they can make becomes it to fit their own requirements.

This independence is the one that most people think about when they listen to the word “free”. It is the flexibility to upgrade with the software, so that it does indeed what you want it to do or stop performing something you would not like.

4. The freedom to distribute copies of your modified versions in front of large audiences, so that the community at large can usually benefit from your improvements.

This freedom is the most important on the freedoms, and it is the freedom that makes a free method useful to its original users and to anyone else. It is the flexibility that allows a team of users (or my explanation specific companies) to create true value added versions in the software, which will serve the needs of a particular subset from the community.
