About Linux Operating System in the Enviorment

Red Hat

 Red Hat is a billion dollar commercial Linux company in the world that puts a lot of effort in developing Linux. They have hundreds of Linux specialists  in the company those are known for their
excellent support. They give their products (Red Hat Enterprise Linux and Fedora)
away for free. While Red Hat Enterprise Linux (RHEL) is well tested before release
and supported for up to seven years after release, Fedora is a distro with faster updates
but without support. Distributions like CentOS, Oracle Enterprise Linux and Scientific Linux are based on Red Hat Enterprise Linux and share many of the same principles, directories and
system administration techniques. Linux Mint, Edubuntu and many other *buntu
named distributions are based on Ubuntu and thus share a lot with Debian. There are
hundreds of other Linux distributions.which are as follows:-

Ubuntu

Canonical started sending out free compact discs with Ubuntu Linux in 2004 and
quickly became popular for home users (many switching from Microsoft Windows).
Canonical wants Ubuntu to be an easy to use graphical Linux desktop without need
to ever see a command line. Of course they also want to make a profit by selling
support for Ubuntu.

 Debian

There is no company behind Debian. Instead there are thousands of well organised
developers that elect a Debian Project Leader every two years. Debian is seen as one
of the most stable Linux distributions. It is also the basis of every release of Ubuntu.
Debian comes in three versions: stable, testing and unstable. Every Debian release is
named after a character in the movie Toy Story.
