The Four Liberties of Free Computer software

A free software is an item of computer code that can be used with out restriction simply by the first users or perhaps by anybody. This can be made by copying the program or changing it, and sharing that in various ways.

The software flexibility 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 created a set of several freedoms with regards to software being considered free:

1 . The freedom to alter the software.

It is the most basic on the freedoms, and it is the one that constitutes a free plan useful to nearly all people. It is also the freedom that allows a group of users to share their modified edition with each other plus the community at large.

2 . The liberty to study this software and appreciate how it works, to enable them to make changes to it to adjust to their own needs.

This independence is the one that a lot of people think of when they hear the word “free”. It is the freedom to upgrade with the method, so that it will what you want it to do or stop carrying out a thing you do not like.

2. The freedom to distribute copies of your customized versions to others, so that the community at large can benefit from your advancements.

This liberty is the most important in the freedoms, in fact it is the freedom that makes a free system useful to the original users and to anyone else. It is the liberty that allows several users (or person companies) to create true value-added versions within the software, that can serve the needs of a particular subset of this community.
