Presentation of the Solaris operating system

The UNIX (r) operating system was developed by AT&T Bell Labs in 1969, it was created as a combination of tools by developers for developers.

The developers of the California Berkeley did modifications to the original source code, and it was called Berkeley Software Distribution (BSD) Unix. The most important contribution from the Berkeley developers was the network software, this meant an important improve to the operating system.

The original version from SUN Operating System as known as SunOS, based in BSD Unix v4.2. In that moment the version from AT&T Unix was known as System V. In 1988, BSD, AT&T Unix and other operating system where combined and from that effort appeared System V v4.0 (SVR4) Unix, this effort also created an standard for the operating systems sector. The new SVR4 where converted in the base not only for Sun OS, but also for AT&T Unix, AIX from IBM and HP-UX from Hewlett-Packard.
