The Four Liberties of Free Software

A free software is a computer code that can be used devoid of restriction simply by the first users or by anyone else. This can be done by copying this program or changing it, and sharing this in various ways.

The software independence 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 formulated a set of several freedoms intended for software to be considered free:

1 . The freedom to alter the software.

This is actually most basic on the freedoms, and it is the one that the free plan useful to nearly all people. It is also the freedom that allows a grouping of users to talk about their modified version with each other as well as the community at large.

2 . The freedom to study the program and learn how it works, to enable them to make changes to it to adjust to their own functions.

This independence is the one that a lot of people imagine when they listen to the word “free”. It is the independence to upgrade with the plan, so that it will what you want this to do or stop performing anything you would not like.

two. The freedom to distribute clones of your revised versions in front of large audiences, so that the community at large can usually benefit from your advancements.

This liberty is the most important for the freedoms, in fact it is the freedom that renders a free plan useful to it is original users and to other people. It is the flexibility that allows a group of users (or person companies) to develop true value added versions on the software, which can serve the needs of a specific subset of your community.
