The Four Freedoms of Free Software program

A free software is a piece of computer code that can be used while not restriction simply by the original users or perhaps by anyone else. This can be created by copying the program or modifying it, and sharing this in various techniques.

The software liberty 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 of their moral rights. He created a set of 4 freedoms meant for software to become considered free:

1 ) The freedom to modify the software.

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

2 . The freedom to study the program and understand how it works, so that they can make changes to it to install their own uses.

This independence is the one that the majority of people think about when they hear the word “free”. It is the liberty to enhance with the application, so that it may what you want it to do or stop performing anything you do not like.

3 or more. The freedom to distribute clones of your customized versions to others, so that the community at large can benefit from your advancements.

This flexibility is the most important on the freedoms, in fact it is the freedom brings about a free software useful to the original users and to other people. It is the flexibility that allows a grouping of users (or person companies) to produce true value-added versions belonging to the software, that may serve the needs of a specific subset on the community.
