+</p>
+
+ <p>This diagram, originally by Chao-Kuei and updated by several
+ others since, explains the different categories of software. It's
+ available as a <a href="/philosophy/category.svg">Scalable Vector
+ Graphic</a> and as an <a href="/philosophy/category.fig">XFig
+ document</a>, under the terms of any of the GNU GPL v2 or later,
+ the GNU FDL v1.2 or later, or the Creative Commons
+ Attribution-Share Alike v2.0 or later.</p>
+
+<h3 id="FreeSoftware">Free software</h3>
+
+ <p>Free software is software that comes with permission for
+ anyone to use, copy, and/or distribute, either verbatim or with
+ modifications, either gratis or for a fee. In particular, this
+ means that source code must be available. “If it's not
+ source, it's not software.” This is a simplified
+ description; see also
+ the <a href="/philosophy/free-sw.html">full
+ definition</a>.</p>
+
+ <p>If a program is free, then it can potentially be included
+ in a free operating system such as GNU, or free versions of
+ the <a href="/gnu/linux-and-gnu.html">GNU/Linux
+ system</a>.</p>
+
+ <p>There are many different ways to make a program free—many
+ questions of detail, which could be decided in more than one way
+ and still make the program free. Some of the possible variations
+ are described below. For information on specific free software
+ licenses, see the <a href="/licenses/license-list.html">license
+ list</a> page.</p>
+
+ <p>Free software is a matter of freedom, not price. But
+ proprietary software companies typically use the term
+ “free software” to refer to price. Sometimes they
+ mean that you can obtain a binary copy at no charge; sometimes
+ they mean that a copy is bundled with a computer that you are
+ buying, and the price includes both. Either way, it has
+ nothing to do with what we mean by free software in the GNU
+ project.</p>
+
+ <p>Because of this potential confusion, when a software company
+ says its product is free software, always check the actual
+ distribution terms to see whether users really have all the
+ freedoms that free software implies. Sometimes it really is free
+ software; sometimes it isn't.</p>
+
+ <p>Many languages have two separate words for
+ “free” as in freedom and “free” as in
+ zero price. For example, French has “libre” and
+ “gratuit”. Not so English; there is a word
+ “gratis” that refers unambiguously to price, but
+ no common adjective that refers unambiguously to freedom. So
+ if you are speaking another language, we suggest you translate
+ “free” into your language to make it clearer. See
+ our list of <a href= "/philosophy/fs-translations.html">
+ translations of the term “free software”</a> into
+ various other languages.</p>
+
+ <p>Free software is often <a
href="/software/reliability.html">more
+ reliable</a> than nonfree software.</p>
+
+<h3 id="OpenSource">Open source software</h3>
+
+ <p>
+ The term “open source” software is used by some
+ people to mean more or less the same category as free
+ software. It is not exactly the same class of software: they
+ accept some licenses that we consider too restrictive, and
+ there are free software licenses they have not
+ accepted. However, the differences in extension of the
+ category are small: nearly all free software is open source,
+ and nearly all open source software is free.</p>
+ <p>We prefer the term “<a
+ href="/philosophy/open-source-misses-the-point.html">free
+ software</a>” because it refers to
+ freedom—something that the term “open
+ source“ does not do.</p>
+
+<h3 id="PublicDomainSoftware">Public domain
+ software</h3>
+
+ <p>Public domain software is software that is not copyrighted. If
+ the source code is in the public domain, that is a special case of
+ <a href="#Non-CopyleftedFreeSoftware">noncopylefted free
+ software</a>, which means that some copies or modified versions
+ may not be free at all.</p>
+
+ <p>In some cases, an executable program can be in the public
domain
+ but the source code is not available. This is not free software,
+ because free software requires accessibility of source code.
+ Meanwhile, most free software is not in the public domain; it is
+ copyrighted, and the copyright holders have legally given
+ permission for everyone to use it in freedom, using a free software
+ license.</p>
+
+ <p>Sometimes people use the term “public domain”
+ in a loose fashion to
+ mean <a href="#FreeSoftware">“free”</a> or
+ “available gratis.” However, “public
+ domain” is a legal term and means, precisely, “not
+ copyrighted”. For clarity, we recommend using
+ “public domain” for that meaning only, and using
+ other terms to convey the other meanings.</p>
+
+ <p>Under the Berne Convention, which most countries have
+ signed, anything written down is automatically
+ copyrighted. This includes programs. Therefore, if you want a
+ program you have written to be in the public domain, you must
+ take some legal steps to disclaim the copyright on it;
+ otherwise, the program is copyrighted.</p>
+
+<h3 id="CopyleftedSoftware">Copylefted software</h3>
+
+ <p>Copylefted software is free software whose distribution
+ terms ensure that all copies of all versions carry more or
+ less the same distribution terms. This means, for instance,
+ that copyleft licenses generally disallow others to add
+ additional requirements to the software (though a limited set
+ of safe added requirements can be allowed) and require making
+ source code available. This shields the program, and its
+ modified versions, from some of the common ways of making a
+ program proprietary.</p>
+
+ <p>Some copyleft licenses, such as GPL version 3, block
+ other means of turning software proprietary, such as <a
+ href="/licenses/rms-why-gplv3.html">tivoization</a>.</p>
+
+ <p>In the GNU Project, we copyleft almost all the software we
+ write, because our goal is to give <em>every</em> user the
freedoms
+ implied by the term “free software.” See our <a
+ href="/licenses/copyleft.html">copyleft article</a> for more
explanation of
+ how copyleft works and why we use it.</p>
+
+ <p>Copyleft is a general concept; to copyleft an actual program,
+ you need to use a specific set of distribution terms. There are
+ many possible ways to write copyleft distribution terms, so in
+ principle there can be many copyleft free software licenses.
+ However, in actual practice nearly all copylefted software uses the
+ <a href="/licenses/gpl.html">GNU General Public
+ License</a>. Two different copyleft licenses are usually
+ “incompatible”, which means it is illegal to merge
+ the code using one license with the code using the other
+ license; therefore, it is good for the community if people use
+ a single copyleft license.</p>
+
+<h3 id="Non-CopyleftedFreeSoftware">Noncopylefted free
software</h3>
+
+ <p>Noncopylefted free software comes from the author with
+ permission to redistribute and modify, and also to add additional
+ restrictions to it.</p>
+
+ <p>If a program is free but not copylefted, then some copies
+ or modified versions may not be free at all. A software
+ company can compile the program, with or without
+ modifications, and distribute the executable file as
+ a <a href="#ProprietarySoftware">proprietary</a> software
+ product.</p>
+
+ <p>The <a href="http://www.x.org">X Window System</a>
+ illustrates this. The X Consortium released X11 with
+ distribution terms that made it noncopylefted free
+ software, and subsequent developers have mostly followed the
+ same practice. A copy which has those
+ distribution terms is free software. However, there are nonfree
+ versions as well, and there are (or at least were) popular
+ workstations and PC graphics boards for which nonfree
+ versions are the only ones that work. If you are using this
+ hardware, X11 is not free software for
+ you. <a href="/philosophy/x.html">The developers of X11 even
+ made X11 nonfree</a> for a while; they were able to do this
+ because others had contributed their code under the same
+ noncopyleft license.</p>
+
+<h3 id="LaxPermissiveLicensedSoftware">Lax permissive licensed
software</h3>
+
+ <p>Lax permissive licenses include the X11 license and the
+ <a href="/licenses/bsd.html">two BSD licenses</a>. These
licenses permit
+ almost any use of the code, including distributing proprietary
+ binaries with or without changing the source code.</p>
+
+<h3 id="GPL-CoveredSoftware">GPL-covered software</h3>
+
+ <p>The <a href="/licenses/gpl.html">GNU GPL (General Public
+ License)</a> is one specific set of distribution terms for
+ copylefting a program. The GNU Project uses it as the distribution
+ terms for most GNU software.</p>
+
+ <p>To equate free software with GPL-covered software is therefore
+ an error.</p>
+
+<h3 id="TheGNUsystem">The GNU operating system</h3>
+
+ <p>The <a href="/gnu/gnu-history.html">GNU operating
system</a> is the
+ Unix-like operating system, which is entirely free software, that
+ we in the GNU Project have developed since 1984.</p>
+
+ <p>A Unix-like operating system consists of many programs. The
+ GNU system includes all of the <a href="#GNUsoftware">official
+ GNU packages</a>. It also includes many other packages, such as
+ the X Window System and TeX, which are not GNU software.</p>
+
+ <p>The first test release of the complete GNU system was in
+ 1996. This includes the GNU Hurd, our kernel, developed since
+ 1990. In 2001 the GNU system (including the GNU Hurd) began
+ working fairly reliably, but the Hurd still lacks some
+ important features, so it is not widely used. Meanwhile,
+ the <a href="/gnu/linux-and-gnu.html">GNU/Linux system</a>,
+ an offshoot of the GNU operating system which uses Linux as
+ the kernel instead of the GNU Hurd, has been a great success
+ since the 90s. As this shows, the GNU system is not a single
+ static set of programs; users and distributors may select
+ different packages according to their needs and desires. The
+ result is still a variant of the GNU system.</p>
+
+ <p>Since the purpose of GNU is to be free, every single
+ component in the GNU operating system is free
+ software. They don't all have to be copylefted, however; any
+ kind of free software is legally suitable to include if it
+ helps meet technical goals.</p>
+
+<h3 id="GNUprograms">GNU programs</h3>
+
+ <p>“GNU programs” is equivalent
+ to <a href="#GNUsoftware">GNU software.</a> A program Foo
is a
+ GNU program if it is GNU software. We also sometimes say it
+ is a “GNU package”.</p>
+
+<h3 id="GNUsoftware">GNU software</h3>
+
+ <p><a href="/software/software.html">GNU software</a>
is
+ software that is released under the auspices of the <a href=
+ "/gnu/gnu-history.html">GNU Project</a>. If a program is GNU
+ software, we also say that it is a GNU program or a GNU
+ package. The README or manual of a GNU package should say it
+ is one; also, the <a href="/directory">Free Software
+ Directory</a> identifies all GNU packages.</p>
+
+ <p>Most GNU software is <a href=
+ "/licenses/copyleft.html">copylefted</a>, but not all; however,
+ all GNU software must be <a href="/philosophy/free-sw.html">free
+ software</a>.</p>
+
+ <p>Some GNU software was written by <a href=
+ "http://www.fsf.org/about/staff/">staff</a> of
+ the <a href="http://www.fsf.org/">Free Software
+ Foundation</a>, but most GNU software comes from many
+ <a href="/people/people.html">volunteers</a>. (Some of
these
+ volunteers are paid by companies or universities, but they are
+ volunteers for us.) Some contributed software is copyrighted
+ by the Free Software Foundation; some is copyrighted by the
+ contributors who wrote it.</p>
+
+<h3 id="FSF-CopyrightedGNUSoftware">FSF-copyrighted GNU
software</h3>
+
+ <p>The developers of GNU packages can transfer the copyright
+ to the FSF, or they can keep it. The choice is theirs.</p>
+
+ <p>If they have <span
class="removed"><del><strong>transfered</strong></del></span> <span
class="inserted"><ins><em>transferred</em></ins></span> the copyright to the
FSF, the program
+ is FSF-copyrighted GNU software, and the FSF can enforce
+ its license. If they have kept the copyright, enforcing the license
+ is their responsibility.</p>
+
+ <p>The FSF does not accept copyright assignments of software
+ that is not an official GNU package, as a rule.</p>
+
+<h3 id="non-freeSoftware">Nonfree software</h3>
+
+ <p>Nonfree software is any software that is not free.
+ Its use, redistribution or modification is prohibited, or
+ requires you to ask for permission, or is restricted so much
+ that you effectively can't do it freely.</p>
+
+<h3 id="ProprietarySoftware">Proprietary software</h3>
+
+ <p>Proprietary software is another name for nonfree software.
+ In the past we subdivided nonfree software into
+ “semifree software”, which could be modified and
+ redistributed noncommercially, and “proprietary
+ software”, which could not be. But we have dropped that
+ distinction and now use “proprietary software” as
+ synonymous with nonfree software.</p>
+
+ <p>The Free Software Foundation follows the rule that we cannot
+ install any proprietary program on our computers except temporarily
+ for the specific purpose of writing a free replacement for that
+ very program. Aside from that, we feel there is no possible excuse
+ for installing a proprietary program.</p>
+
+ <p>For example, we felt justified in installing Unix on our
+ computer in the 1980s, because we were using it to write a free
+ replacement for Unix. Nowadays, since free operating systems are
+ available, the excuse is no longer applicable; we do not use any
+ nonfree operating systems, and any new computer we install
+ must run a completely free operating system.</p>
+
+ <p>We don't insist that users of GNU, or contributors to GNU, have
+ to live by this rule. It is a rule we made for ourselves. But we
+ hope you will follow it too, for your freedom's sake.</p>
+
+
+<h3 id="freeware">Freeware</h3>
+
+ <p>The term “freeware” has no clear accepted
+ definition, but it is commonly used for packages which permit
+ redistribution but not modification (and their source code is
+ not available). These packages are <em>not</em> free
software,
+ so please don't use “freeware” to refer to free
+ software.</p>
+
+<h3 id="shareware">Shareware</h3>
+
+ <p>Shareware is software which comes with permission for people to
+ redistribute copies, but says that anyone who continues to use a
+ copy is <em>required</em> to pay a license fee.</p>
+
+ <p>Shareware is not free software, or even semifree. There are two
+ reasons it is not:</p>
+
+ <ul>
+ <li>For most shareware, source code is not available; thus, you
+ cannot modify the program at all.</li>
+ <li>Shareware does not come with permission to make a copy and
+ install it without paying a license fee, not even for individuals
+ engaging in nonprofit activity. (In practice, people often
+ disregard the distribution terms and do this anyway, but the terms
+ don't permit it.)</li>
+ </ul>
+
+<h3 id="PrivateSoftware">Private software</h3>
+ <p>Private or custom software is software developed for one user
+ (typically an organization or company). That user keeps it and uses
+ it, and does not release it to the public either as source code or
+ as binaries.</p>
+ <p>A private program is free software (in a somewhat trivial
+ sense) if its sole user has the four freedoms. In particular,
+ if the user has full rights to the private program, the program is
+ free. However, if the user distributes copies to others and does
+ not provide the four freedoms with those copies, those copies
+ are not free software.</p>
+
+ <p>Free software is a matter of freedom, not access. In
+ general we do not believe it is wrong to develop a program and
+ not release it. There are occasions when a program is so
+ important that one might argue that withholding it from the
+ public is doing wrong to humanity. However, such cases are
+ rare. Most programs are not that important, and declining to
+ release them is not particularly wrong. Thus, there is no
+ conflict between the development of private or custom software
+ and the principles of the free software movement.</p>
+
+ <p>Nearly all employment for programmers is in development of
+ custom software; therefore most programming jobs are, or could be,
+ done in a way compatible with the free software movement.</p>
+
+<h3 id="commercialSoftware">Commercial software</h3>
+
+ <p> “Commercial” and “proprietary” are
+ not the same! Commercial software is software developed by a
+ business as part of its business. Most commercial software
+ is <a href="#ProprietarySoftware">proprietary</a>, but there
+ is commercial free software, and there is noncommercial
+ nonfree software.</p>
+
+ <p>For example, GNU Ada is developed by a company. It is always
+ distributed under the terms of the GNU GPL, and every copy is
+ free software; but its developers sell support contracts. When
+ their salesmen speak to prospective customers, sometimes the
+ customers say, “We would feel safer with a commercial
+ compiler.” The salesmen reply, “GNU
+ Ada <em>is</em> a commercial compiler; it happens to be free
+ software.”</p>
+ <p>For the GNU Project, the priorities are in the other order:
+ the important thing is that GNU Ada is free software; that
+ it is commercial is just a detail. However, the additional
+ development of GNU Ada that results from its being commercial
+ is definitely beneficial.</p>
+ <p>Please help spread the awareness that free commercial
+ software is possible. You can do this by making an effort not
+ to say “commercial” when you mean
+ “proprietary.”</p>
