The Four Liberties of Free Software

A free software is a computer code that can be used devoid of restriction by the original users or by anybody else. This can be made by copying this software or enhancing it, and sharing this in various methods.

The software flexibility movement was started in the 1980s simply by 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 created a set of several freedoms intended for software to become considered free:

1 ) The freedom to switch the software.

This is actually the most basic of this freedoms, and it is the one that constitutes a free program useful to people. It is also the freedom that allows a team of users to talk about their modified version with each other and the community at large.

2 . The liberty to study the program and learn how it works, in order to make changes to it to install their own purposes.

This liberty is the one that most people think about when they notice the word “free”. It is the independence to tinker with the program, so that it truly does what you want this to do or perhaps stop undertaking something you don’t like.

four. 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 freedom is the most important within the freedoms, in fact it is the freedom that produces a free method useful to its original users and to other people. It is the independence that allows a team of users (or specific companies) to create true value-added versions for the software, which can serve the needs of a specific subset of the community.
