behind every OS
Short for Microsoft Disk operating system, MS-DOS is a non-graphical command line operating system derived from 86-DOS that was created for IBM compatible computers. MS-DOS originally written by Tim Paterson and introduced by Microsoft in August 1981 and was last updated in 1994 when MS-DOS 6.22 was released. Today, MS-DOS is no longer used. But the command shell, more commonly known as the Windows command line is still used by many users

2ND leader in Operating system
Slackware Linux -1992
came on 24 floppy disks,highly technical and very few custom options.All configurations are made by editing text files.Bug free
Debian GNU/Linux -1993
Very stable,remarkable quality control , supports more processor architectures than any other Linux distribution . Very conservative .
Arch Linux-2002
Excellent software management infrastructure; unparalleled customization and tweaking options,online documentation.Occasional instability and risk of breakdown, infrequent install media releases.
PCLinuxOS -2003
Out-of-the-box support for graphics drivers, browser plugins and media codes, rolling-release update mechanism; up-to-date software. No out-of-the-box support for non-English languages; lacks release planning and security advisories
CentOS- 2003
Extremely well-tested, stable and reliable; free to download and use; comes with 5-years of free security updates.Lacks latest Linux technologies; occasionally the project fails to live up its promise to deliver timely security updates and new stable releases.
Ubuntu 2004
Fixed release cycle and support period; novice-friendly; wealth of documentation, both official and user-contributed. Lacks compatibility with Debian; frequent major changes tend to drive some users away
Fedora -2004
Highly innovative; outstanding security features; large number of supported packages; strict adherence to the free software philosophy; availability of live CDs featuring many popular desktop environments.Fedora's priorities tend to lean towards enterprise features, rather than desktop usability; some bleeding edge features, such as early switch to KDE 4 and GNOME 3, occasionally alienate some desktop users
Linux Mint- 2006
Superb collection of "minty" tools developed in-house, hundreds of user-friendly enhancements, inclusion of multimedia codes, open to users' suggestions. The alternative "community" editions don't always include the latest features, the project does not issue security advisories.
Beginner-friendly; excellent central configuration utility; very good out-of-the-box support for dozens of languages; installable live media. Lacks reputation and mindshare following its fork from Mandriva, some concern over the developers ability to maintain the distribution long-term on a volunteer basis.
FreeBSD 2010
Fast and stable; availability of over 21,000 software applications (or "ports") for installation; very good documentation. Tends to lag behind Linux in terms of support for new and exotic hardware, limited availability of commercial applications; lacks graphical configuration tools

basically the layer beneath every OS
