The Berkeley Software Distribution [a] (BSD), also known as Berkeley Unix or BSD Unix, is a discontinued Unix operating system developed and distributed by the Computer Systems Research Group (CSRG) at the University of California, Berkeley, beginning in 1978.
Other universities became interested in the software at Berkeley, and so in 1977 Joy started compiling the first Berkeley Software Distribution (1BSD), which was released on March 9, 1978. [2] 1BSD was an add-on to Version 6 Unix rather than a complete operating system in its own right. Some thirty copies were sent out. [1]
Because this Berkeley Software Distribution (BSD) contained copyrighted AT&T Unix source code, it was only available to organizations with a source code license for Unix from AT&T. Students and faculty at the CSRG audited the software code for the TCP/IP stack, removing all the AT&T intellectual property, and released it to the general public ...
NetBSD is a freely redistributable, open source version of the Unix-derivative Berkeley Software Distribution (BSD) computer operating system. It was the second open source BSD descendant to be formally released, after 386BSD, and continues to be actively developed.
Simplified evolution of Unix systems. The Mach kernel was a fork from BSD 4.3 that led to NeXTSTEP / OpenStep, upon which macOS and iOS are based.. The Computer Systems Research Group (CSRG) was a research group at the University of California, Berkeley, that was dedicated to enhancing AT&T Unix operating system and funded by the Defense Advanced Research Projects Agency.
The AT&T 3B2 became the official "porting base." SCO UNIX was based upon SVR3.2, as was ISC 386/ix. Among the more obscure distributions of SVR3.2 for the 386 were ESIX 3.2 by Everex and "System V, Release 3.2" sold by Intel themselves; these two shipped "plain vanilla" AT&T's codebase. [14] IBM's AIX operating system is an SVR3 derivative.
Berkeley Software Design, Inc. (BSDI or, later, BSDi), was a software company founded in 1991 by members of the Computer Systems Research Group (CSRG), known for developing and selling BSD/OS (originally known as BSD/386), a commercial and partially proprietary variant of the BSD Unix operating system for PCs.
In the mid-1980s, the three common versions of Unix were AT&T's System III, the basis of Microsoft's Xenix and the IBM-endorsed PC/IX, among others; AT&T's System V, which it sought to establish as the new Unix standard; [2] and the Berkeley Software Distribution (BSD). All were derived from AT&T's Research Unix but had diverged considerably ...
