Solaris is a computer operating system, the proprietary Unix variant developed by Sun Microsystems. Solaris consists of the SunOS UNIX base operating system plus a graphical user environment. Solaris is written in a platform-independent manner and is available for SPARC and x86 processors (including x86_64). Historically, Solaris used to be a proprietary operating system, however, starting from version 10, its licence has changed and the product is now distributed free of charge for any system or purpose, while its source code is available from OpenSolaris.org under a license approved by Open Source Initiative (OSI). This Solaris 10 Training Video DVD will help you get up and running and using Solaris 10 like a pro.
