Solaris
Solaris is a computer operating system developed by Sun Microsystems. It is certified as a version of Unix. Although Solaris proper is still proprietary software, the core OS has been made into an open source project, OpenSolaris.
In the early 1990s Sun replaced the BSD-derived SunOS 4 with a version of UNIX System V Release 4 (SVR4), jointly developed with AT&T. The underlying release name was SunOS 5.0, but a new marketing name was introduced at the same time: Solaris 2.
(SunOS 4.1.x micro releases were also retroactively named Solaris 1, a convention generally ignored; the name Solaris is almost exclusively used to refer to SVR4-derived SunOS 5.0 and later.)
Solaris is considered to be the SunOS operating system plus a graphical user environment (see Desktop Environments below), ONC+, and other components. The SunOS minor version is included in the Solaris release name; for example, Solaris 2.4 incorporated SunOS 5.4. After Solaris 2.6, Sun dropped the "2." from the name, so what we know as Solaris 7 incorporates SunOS 5.7, and the latest release SunOS 5.10 forms the core of Solaris 10.
Solaris uses a common code base for the architectures it supports: SPARC and x86 (including AMD64/EM64T). It was also ported to the PowerPC architecture (PReP platform) for version 2.5.1, but the port was cancelled almost as soon as it was released. Support for Itanium was at one time planned but never brought to market.Sun also plans to implement Linux ABIs in Solaris 10, allowing Solaris to run native Linux binaries on x86 systems.
