BSD licenses represent a family of permissive free software licences. The Regents of the University of California make up the governing board of the University of California. N/A or n/a is a common abbreviation for not available or not applicable, used to indicate the deliberate omission of information from a table or listing Copyright is a legal concept enacted by Governments, giving the creator of an original work of authorship Exclusive rights to control its distribution usually for The Debian Free Software Guidelines ( DFSG) is a set of guidelines that the Debian Project uses to determine whether a software license is a Free software license Free software or software libre is Software that can be used studied and modified without restriction and which can be copied and redistributed in modified or unmodified An open source license is a copyright License for Computer software that makes the source code available under terms that allow for modification and redistribution License compatibility refers to the problem with licenses of software packages which can contain contradictory requirements rendering it impossible to combine Source code The original was used for the Berkeley Software Distribution (BSD), a Unix-like operating system for which the license is named. A Unix-like (sometimes shortened to *nix) Operating system is one that behaves in a manner similar to a Unix system while not necessarily conforming The original owners of BSD were the Regents of the University of California because BSD was first written at the University of California, Berkeley. The Regents of the University of California make up the governing board of the University of California. The University of California Berkeley (also referred to as Cal, Berkeley and UC Berkeley) is a major research university located in Berkeley The first version of the license was revised, and the resulting licenses are more properly called modified BSD licenses. Permissive licenses, sometimes with important differences pertaining to license compatibility, are referred to as "BSD-style licenses". License compatibility refers to the problem with licenses of software packages which can contain contradictory requirements rendering it impossible to combine Source code Several BSD-like licenses, including the New BSD license, have been vetted by the Open Source Initiative as meeting their definition of open source. Broadly vetting is a process of examination and evaluation Specifically vetting often refers to performing a Background check on someone before offering them employment The Open Source Initiative is an organization dedicated to promoting Open-source software. Open source is a development methodology which offers practical accessibility to a product's source (goods and knowledge
The licenses have few restrictions compared to other free software licenses such as the GNU General Public License or even the default restrictions provided by copyright, putting it relatively closer to the public domain. Copyright is a legal concept enacted by Governments, giving the creator of an original work of authorship Exclusive rights to control its distribution usually for The public domain is a range of abstract materials &ndash commonly referred to as Intellectual property &ndash which are not owned or controlled by anyone
The text of the license is considered to be in the public domain and thus may be modified without restriction. The public domain is a range of abstract materials &ndash commonly referred to as Intellectual property &ndash which are not owned or controlled by anyone

The BSD License allows proprietary commercial use, and for the software released under the license to be incorporated into proprietary commercial products. Works based on the material may even be released under a proprietary license (but still must maintain the license requirements). Some notable examples of this are the use of BSD networking code in Microsoft products, and the use of numerous FreeBSD components in Mac OS X.

It is possible for something to be distributed with the BSD License and some other license to apply as well. This was in fact the case with very early versions of BSD itself, which included proprietary material from AT&T.

As originally distributed, the BSD license had an extra clause, requiring authors of all works deriving from a BSD-licensed work to include an acknowledgment of the original source. This is numbered as clause 3 in the original license text:
* 3. All advertising materials mentioning features or use of this software* must display the following acknowledgement:* This product includes software developed by the University of* California, Berkeley and its contributors.
This clause has been objected to on the grounds that as people changed the license to reflect their name or organisation it led to escalating advertising requirements when programs were combined together in a software distribution—every occurrence of the license with a different name requires a separate acknowledgement— the Free Software Foundation has cited the requirement for 75 such acknowledgments when advertising a 1997 version of NetBSD. The Free Software Foundation ( FSF) is a Non-profit corporation founded by Richard Stallman on 4 October 1985 to support the Free software movement NetBSD is a freely redistributable Open source version of the Unix -derivative Berkeley Software Distribution (BSD Computer Operating  In addition, it presents a legal problem for those wishing to publish BSD-licensed software which relies upon separate programs using the more-restrictive GPL: the advertising clause is incompatible with the GPL, which does not allow the addition of restrictions beyond those it already imposes. License compatibility refers to the problem with licenses of software packages which can contain contradictory requirements rendering it impossible to combine Source code
The advertising clause was removed from the official BSD license text on July 22, 1999 by William Hoskins, the director of the office of technology licensing for Berkeley.

The original license is now sometimes called "BSD-old" or "4-clause BSD", while the current revision of the BSD license is sometimes referred to by names including "BSD-new", "revised BSD", or "3-clause BSD".
Several free or open source licenses that derive from or are similar to the BSD license are widely used:
