'''Berkeley Software Distribution''' ('''BSD''', tudi '''Berkeley Unix''') je [[Unix]]u-podoben [[operacijski sistem]], ki ga je med leti 1977 in 1995 razvijala in distribuirala skupina [[Computer Systems Research Group]] [[Univerza v Kaliforniji|Univerze v Kaliforniji]].

BSD has been the base of a large number of operating systems. Most notable among these today is perhaps the major [[open source]] BSDs, [[FreeBSD]], [[NetBSD]] and [[OpenBSD]], which are all derived from [[386BSD]] and [[4.4BSD]]-Lite, by various routes. Both NetBSD and FreeBSD started life in 1993, initially derived from 386BSD, but in 1994 migrating to a 4.4BSD-Lite code base. OpenBSD was [[Fork (software development)|forked]] in 1995 from NetBSD. The three most notable descendants in current use —sometimes known as ''the BSDs''— have themselves spawned a number of children, including [[DragonFly BSD]], [[FreeSBIE]], [[MirOS BSD]], [[DesktopBSD]], and [[PC-BSD]]. They are targeted at an array of systems for different purposes and are common in government facilities, universities and in commercial use. A number of commercial operating systems are also partly or wholly based on BSD or its descendants, including [[Sun Microsystems|Sun's]] [[SunOS]] and [[Apple Inc.]]'s [[Mac OS X]].

** [[Juniper Networks]] JunOS, za [[router]]je Juniper
Most of the current BSD operating systems are [[open source]] and available for download, free of charge, under the [[BSD License]], the most notable exception being Mac OS X. They also generally use a [[monolithic kernel]] architecture, apart from Mac OS X and DragonFly BSD which feature [[hybrid kernel]]s. The various open source BSD projects generally develop the kernel and [[userland]] programs and libraries together, the source code being managed using a single central source repository.
** [[Apple|Applov]] [[Darwin (operacijski sistem)|Darwin]], jedro [[Mac OS X]]
* [[NetBSD]], poudarek na preprostosti
In the past, BSD was also used as a basis for several proprietary versions of UNIX, such as [[Sun Microsystems|Sun]]'s [[SunOS]], [[Sequent Computer Systems|Sequent]]'s [[Dynix]], [[NeXT]]'s [[NeXTSTEP]], [[Digital Equipment Corporation|DEC]]'s [[Ultrix]] and OSF/1 AXP (now [[Tru64 UNIX]]). Of these, only the last is still currently supported in its original form. Parts of NeXT's software became the foundation for [[Mac OS X]], among the most commercially successful BSD variants in the general market.
** [[OpenBSD]], osredotoča se na prenosljivost, standarizacijo in varnost, integrirana je tudi kriptacija
* DEC's [[Ultrix]]
A selection of significant Unix versions and [[Unix-like]] operating systems that descend from BSD includes:
*[[OSF/1]]
* zgodnje verzije [[Sun Microsystems|Sunovega]] [[SunOS]] (do verzije SunOS 4.1.4)
* [[FreeBSD]], a major open source effort focusing on performance and the [[x86]] platform.
* [[NeXT]] [[NEXTSTEP]] in [[OpenStep|OPENSTEP]], predhodnika prej omenjenega Darwina
** [[DragonFly BSD]], a fork of FreeBSD to follow an alternative design, particularly related to [[Symmetric multiprocessing|SMP]].
* [[386BSD]], prvi na BSD-ju temelječ operacijski sistem in predhodnik večine trenutnih BSD sistemov
** [[PC-BSD]] and [[DesktopBSD]], distributions of FreeBSD with emphasis on ease of use and user friendly interfaces for the desktop/laptop PC user.
* [[DEMOS]], [[Sovjetska zveza|sovjetski]] klon BSD-ja
** [[Nokia IPSO]] (IPSO SB variant), the FreeBSD-based OS used in [[Nokia]] Firewall Appliances.
* [[BSD/OS]], lastniški BSD za PCje
** [[Juniper Networks]] JunOS, the operating system for Juniper routers, a customized version of FreeBSD, and a variety of other embedded operating systems
** [[Apple Inc.]]'s [[Darwin (operating system)|Darwin]], the core of [[Mac OS X]]; built on the [[XNU|XNU kernel]] (part [[Mach (kernel)|Mach]], part FreeBSD, part Apple-derived code) and a [[Userland (computing)|userland]] much of which comes from [[FreeBSD]]
* [[NetBSD]], an open source BSD with an emphasis on portability and clean design.
** [[OpenBSD]], a 1995 [[Fork (software development)|fork]] of NetBSD, focuses on portability, standardization, correctness, proactive security and integrated cryptography.
* DEC's [[Ultrix]], the official version of Unix for its [[PDP-11]], [[VAX]], and [[DECstation]] systems
*[[OSF/1]], a [[microkernel]]-based UNIX developed by the [[Open Software Foundation]], incorporating the [[Mach kernel]] and parts of 4BSD
** [[Tru64 UNIX]] (formerly DEC OSF/1 AXP or Digital UNIX), the port of [[OSF/1]] for [[DEC Alpha]]-based systems from [[Digital Equipment Corporation|DEC]], [[Compaq]] and [[Hewlett-Packard|HP]].
* Early versions of [[Sun Microsystems]] [[SunOS]] (up to SunOS 4.1.4), an enhanced version of 4BSD for the Sun [[Motorola]] [[68k]]-based [[Sun-2]] and [[Sun-3]] systems, [[SPARC]]-based systems, and [[x86]]-based [[Sun386i]] systems.
* [[NeXT]] [[NEXTSTEP]] and [[OpenStep|OPENSTEP]], based on the Mach kernel and 4BSD; the ancestor of [[Mac OS X]]
* [[386BSD]], the first open source BSD-based operating system and the ancestor of most current BSD systems
* [[DEMOS]], a [[Soviet Union|Soviet]] BSD clone
* [[BSD/OS]], a (now defunct) proprietary BSD for PCs
