A free software is a bit of computer code that can be used while not restriction simply by the initial users or by anybody else. This can be made by copying this software or changing it, and sharing this in various ways.

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 pertaining to software to become considered free:

1 ) The freedom to alter the software.

This is actually the most basic for the freedoms, and it go right here is the one that constitutes a free program useful to nearly all people. It is also the freedom that allows a team of users to talk about their modified variant with each other as well as the community in particular.

2 . The freedom to study this software and understand how it works, to enable them to make becomes it to match their own reasons.

This independence is the one that most of the people consider when they hear the word “free”. It is the freedom to tinker with the plan, so that it may what you want it to do or perhaps stop doing anything you don’t like.

3 or more. The freedom to distribute copies of your changed versions to others, so that the community at large can benefit from your improvements.

This flexibility is the most important of the freedoms, in fact it is the freedom which enables a free application useful to the original users and to anybody. It is the independence that allows a grouping of users (or specific companies) to create true value-added versions in the software, which often can serve the needs of a particular subset belonging to the community.
