SOLARIS OS Solaris  is a Unix operating system originally developed by Sun Microsystems. It superseded their earlier SunOS in 1993. In 2010, after the Sun acquisition by Oracle, it was renamed  Oracle Solaris . Solaris is known for its scalability, especially on SPARC systems, and for originating many innovative features such as DTrace, ZFSand Time Slider. Solaris supports SPARC and x86-64 workstations and servers from Oracle and other vendors. Solaris is registered as compliant with the Single UNIX Specification. Historically, Solaris was developed as proprietary software. In June 2005, Sun Microsystems released most of the codebase under the CDDL license, and founded the OpenSolaris open-source project. With OpenSolaris, Sun wanted to build a developer and user community around the software. After the acquisition of Sun Microsystems in January 2010, Oracle decided to discontinue the OpenSolaris distribution and the development model. In August 2010, Oracle discontinued prov

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 for this reason. Berkeley Software Distribution (BSD) was a Unix operating system derivative developed and distributed by the Computer Systems Research Group (CSRG) of the University of California, Berkeley, from 1977 to 1995. Today, the term "BSD" is often used non-specifically to refer to any of the BSD descendants which form a branch of the family of Unix-like operating systems. Operating systems derived from the original Berkeley source code, such as FreeBSD and OpenBSD, are actively maintained. BSD was initially called Berkeley Unix because it shared the same source code with AT&T Research Unix. In the 1980s, B

LINUX Linux is a family of free and open-source software operating systems built around the Linux kernel. Typically, Linux is packaged in a form known as a Linux distribution (or distro for short) for both desktop and server use. The defining component of a Linux distribution is the Linux kernel, an operating system kernel first released on September 17, 1991, by Linus Torvalds.  Many Linux distributions use the word "Linux" in their name. The Free Software Foundation uses the name GNU/Linux to refer to the operating system family, as well as specific distributions, to emphasize that most Linux distributions are not just the Linux kernel, and that they have in common not only the kernel, but also numerous utilities and libraries, a large proportion of which are from the GNU project. This has led to some controversy. Linux was originally developed for personal computers based on the Intel x86 architecture, but has since been ported to more platforms than any other op
