Free software or software libre is software Computer software, or just software is a general term used to describe the role that computer programs, procedures and documentation play in a computer system that can be used, studied, and modified without restriction, and which can be copied and redistributed in modified or unmodified form either without restriction, or with minimal restrictions only to ensure that further recipients can also do these things and that manufacturers of consumer-facing hardware allow user modifications to their hardware. Free software is available gratis (free of charge) in most cases.
In practice, for software to be distributed as free software, the human-readable form of the program (the source code In computer science, source code is any collection of statements or declarations written in some human-readable computer programming language. Source code allows the programmer to communicate with the computer using a reserved number of instructions) must be made available to the recipient along with a notice granting the above permissions. Such a notice either is a "free software license A free software licence is a software licence which grants recipients rights to modify and redistribute the software which would otherwise be prohibited by copyright law. A free software licence grants, to the recipients, freedoms in the form of permissions to modify or distribute copyrighted work", or a notice that the source code is released into the public domain The public domain is a range of abstract materials—commonly referred to as intellectual property—which are not owned or controlled by anyone. The term indicates that these materials are therefore "public property", and available for anyone to use for any purpose. The public domain can be defined in contrast to several forms of.
The free software movement The free software movement is a social movement which aims to promote user's rights to access and modify software. The alternative terms "software libre", "open source", and "FOSS" are associated with the free software movement. Although drawing on traditions and philosophies among members of the 1970s hacker culture, was conceived in 1983 by Richard Stallman Richard Matthew Stallman , often abbreviated to "rms", is an American software freedom activist, hacker, and software developer. In September 1983, he launched the GNU Project to create a free Unix-like operating system, and has been the project's lead architect and organizer. With the launch of the GNU Project, he started the free to satisfy the need for and to give the benefit of "software freedom" to computer users.[1] The Free Software Foundation The Free Software Foundation is a non-profit corporation founded by Richard Stallman on 4 October 1985 to support the free software movement, a copyleft-based movement which aims to promote the universal freedom to distribute and modify computer software. The FSF is incorporated in Massachusetts, USA was founded in 1985 to provide the organizational structure which Stallman correctly foresaw would be necessary to advance his Free Software ideas.
From 1998 onward, alternative terms for free software Alternative terms for free software have been a controversial issue among free software users from the late 1990s onwards. Coined in 1983 by Richard Stallman, "free software" is used to describe software which can be used, modified, and redistributed with little or no restriction. These freedoms are formally described in The Free came into use. The most common are "software libre", "free and open source software Free and open source software, also F/OSS, FOSS, or FLOSS is software which is liberally licensed to grant the right of users to study, change, and improve its design through the availability of its source code. This approach has gained both momentum and acceptance as the potential benefits have been increasingly recognized by both individuals and" ("FOSS") and "free, libre and open source software" ("FLOSS"). The "Software Freedom Law Center" was founded in 2005 to protect and advance FLOSS.[2] The antonym of free software is "proprietary software Proprietary software is any computer software with restrictions on use or private modification, or with restrictions judged to be excessive on copying or publishing of modified or unmodified versions. The term proprietary software is thus the opposite of free software, generally speaking. These restrictions are placed on it by one of its" or "non-free software".
Free software, which may or may not be distributed free of charge, is distinct from "freeware Freeware is computer software that is available for use at no cost or for an optional fee. Freeware is generally proprietary software available at zero price. The author usually restricts one or more rights to copy, distribute, and make derivative works of the software" which, by definition, does not require payment for use. The authors or copyright holders of freeware typically retain all other rights to the software; users of freeware, in general, cannot study, modify, or redistribute it.[3][4]
Since free software may be freely redistributed it is generally available at little or no cost. Free software business models are usually based on adding value such as applications, support, training, customization, integration, or certification. At the same time, some business models which work with proprietary software Proprietary software is any computer software with restrictions on use or private modification, or with restrictions judged to be excessive on copying or publishing of modified or unmodified versions. The term proprietary software is thus the opposite of free software, generally speaking. These restrictions are placed on it by one of its are not compatible with free software, such as those that depend on a user paying for a license in order to lawfully use a software product.
