386BSD
386BSD (also known as "Jolix") is a discontinued Unix operating system based on the Berkeley Software Distribution (BSD). It was released in 1992 and ran on PC-compatible computer systems based on the 32-bit Intel 80386 microprocessor. 386BSD innovations included role-based security, ring buffers, self-ordered configuration and modular kernel design. History 386BSD was written mainly by Berkeley alumni Lynne Jolitz and William Jolitz. William Jolitz had considerable experience with prior BSD releases while at the University of California at Berkeley (2.8 and 2.9BSD) and both contributed code developed at Symmetric Computer Systems during the 1980s, to Berkeley. Work on porting 4.3BSD-Reno and later 4.3BSD Net/2 to the Intel 80386 was done for the University of California by William Jolitz at Berkeley. 4.3BSD Net/2 was an incomplete non-operational release, with portions withheld by the University of California as ''encumbered'' (i.e. subject to an AT&T UNIX source cod ...

NetBSD
NetBSD is a free and open-source Unix operating system based on the Berkeley Software Distribution (BSD). It was the first open-source BSD descendant officially released after 386BSD was forked. It continues to be actively developed and is available for many platforms, including servers, desktops, handheld devices, and embedded systems. The NetBSD project focuses on code clarity, careful design, and portability across many computer architectures. Its source code is publicly available and permissively licensed. History NetBSD was originally derived from the 4.3BSD-Reno release of the Berkeley Software Distribution from the Computer Systems Research Group of the University of California, Berkeley, via their Net/2 source code release and the 386BSD project. The NetBSD project began as a result of frustration within the 386BSD developer community with the pace and direction of the operating system's development. The four founders of the NetBSD project, Chris Demetriou, Theo d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
FreeBSD
FreeBSD is a free and open-source Unix-like operating system descended from the Berkeley Software Distribution (BSD), which was based on Research Unix. The first version of FreeBSD was released in 1993. In 2005, FreeBSD was the most popular open-source BSD operating system, accounting for more than three-quarters of all installed and permissively licensed BSD systems. FreeBSD has similarities with Linux, with two major differences in scope and licensing: FreeBSD maintains a complete system, i.e. the project delivers a kernel, device drivers, userland utilities, and documentation, as opposed to Linux only delivering a kernel and drivers, and relying on third-parties for system software; FreeBSD source code is generally released under a permissive BSD license, as opposed to the copyleft GPL used by Linux. The FreeBSD project includes a security team overseeing all software shipped in the base distribution. A wide range of additional third-party applications may be i ...

William Jolitz
William Frederick Jolitz (February 22, 1957 – March 2, 2022), commonly known as Bill Jolitz, was an American software engineer best known for developing the 386BSD operating system from 1989 to 1994 along with his wife Lynne Jolitz. Before 386BSD, Bill Jolitz designed the Symmetric 375 with an NSC 16032 (NS32000) CPU running 4.2BSD. His own Symmetric Computer Systems sold them from 1987 until 1988. Jolitz received his BA in Computer Science from UC Berkeley. He and his wife resided in Los Gatos, California.

Berkeley Software Distribution
The Berkeley Software Distribution or Berkeley Standard Distribution (BSD) is a discontinued operating system based on Research Unix, developed and distributed by the Computer Systems Research Group (CSRG) at the University of California, Berkeley. The term "BSD" commonly refers to its open-source descendants, including FreeBSD, OpenBSD, NetBSD, and DragonFly BSD. BSD was initially called Berkeley Unix because it was based on the source code of the original Unix developed at Bell Labs. In the 1980s, BSD was widely adopted by workstation vendors in the form of proprietary Unix variants such as DEC Ultrix and Sun Microsystems SunOS due to its permissive licensing and familiarity to many technology company founders and engineers. Although these proprietary BSD derivatives were largely superseded in the 1990s by UNIX SVR4 and OSF/1, later releases provided the basis for several open-source operating systems including FreeBSD, OpenBSD, NetBSD, DragonFly BSD, Darwi ...

BSD/OS
BSD/OS (originally called BSD/386 and sometimes known as BSDi) is a discontinued proprietary version of the BSD operating system developed by Berkeley Software Design, Inc. (BSDi). BSD/OS had a reputation for reliability in server roles; the renowned Unix programmer and author W. Richard Stevens used it for his own personal web server. History BSDi was formed in 1991 by members of the Computer Systems Research Group (CSRG) at UC Berkeley to develop and sell a proprietary version of BSD Unix for PC compatible systems with Intel 386 (or later) processors. This made use of work previously done by Bill Jolitz to port BSD to the PC platform. BSD/386 1.0 was released in March 1993. The company sold licenses and support for it, taking advantage of terms in the BSD License which permit use of the BSD software in proprietary systems, as long the author is credited. The company in turn contributed code and resources to the development of non-proprietary BSD operating systems. In the mean ...

X86 Architecture
x86 (also known as 80x86 or the 8086 family) is a family of complex instruction set computer (CISC) instruction set architectures initially developed by Intel based on the Intel 8086 microprocessor and its 8088 variant. The 8086 was introduced in 1978 as a fully 16-bit extension of Intel's 8-bit 8080 microprocessor, with memory segmentation as a solution for addressing more memory than can be covered by a plain 16-bit address. The term "x86" came into being because the names of several successors to Intel's 8086 processor end in "86", including the 80186, 80286, 80386 and 80486 processors. The term is not synonymous with IBM PC compatibility, as this implies a multitude of other computer hardware. Embedded systems and general-purpose computers used x86 chips before the PC-compatible market started, some of them before the IBM PC (1981) debut. , most desktop and laptop computers sold are based on the x86 architecture family, while mobile categories such as smart ...

AT&T UNIX
The history of Unix dates back to the mid-1960s, when the Massachusetts Institute of Technology, AT&T Bell Labs, and General Electric were jointly developing an experimental time-sharing operating system called Multics for the GE-645 mainframe. Multics introduced many innovations, but also had many problems. Bell Labs, frustrated by the size and complexity of Multics but not its aims, slowly pulled out of the project. Their last researchers to leave Multics – among them Ken Thompson, Dennis Ritchie, Doug McIlroy, and Joe Ossanna – decided to redo the work, but on a much smaller scale. APDF/ref> In 1979, Ritchie described the group's vision for Unix: 1960s In the late 1960s, Bell Labs was involved in a project with MIT and General Electric to develop a time-sharing system, called Multiplexed Information and Computing Service (Multics), allowing multiple users to access a mainframe simultaneously. Dissatisfied with the project's progress, Bell Labs management ultimately wi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
UNIX System Laboratories, Inc
Unix (; trademarked as UNIX) is a family of multitasking, multiuser computer operating systems that derive from the original AT&T Unix, whose development started in 1969 at the Bell Labs research center by Ken Thompson, Dennis Ritchie, and others. Initially intended for use inside the Bell System, AT&T licensed Unix to outside parties in the late 1970s, leading to a variety of both academic and commercial Unix variants from vendors including University of California, Berkeley ( BSD), Microsoft (Xenix), Sun Microsystems (SunOS/ Solaris), HP/ HPE (HP-UX), and IBM (AIX). In the early 1990s, AT&T sold its rights in Unix to Novell, which then sold the UNIX trademark to The Open Group, an industry consortium founded in 1996. The Open Group allows the use of the mark for certified operating systems that comply with the Single UNIX Specification (SUS). Unix systems are characterized by a modular design that is sometimes called the "Unix philosophy". According to this philosophy, t ...

Berkeley Software Design
Berkeley Software Design, Inc. (BSDI or, later, BSDi), was a corporation which developed, sold licenses for, and supported BSD/OS (originally known as BSD/386), a commercial and partially proprietary variant of the BSD Unix operating system for PC compatible (and later, other) computer systems. The name was chosen for its similarity to "Berkeley Software Distribution" the source of its primary product (specifically 4.3BSD Networking Release 2). BSDI was founded by Rick Adams and members of the Computer Systems Research Group (CSRG) at the University of California, Berkeley, including Keith Bostic, Kirk McKusick, Mike Karels, Bill Jolitz and Donn Seeley. Jolitz, Seeley and Trent Hein were working for Rick Adam's UUNET at the time and became BSDI's first employees when the company began operations in 1991. In December 1991, USENIX Secretary and Former Head of Software at Convex Computer, Rob Kolstad from University of Illinois, was hired and would take over company operatio ...
