i want to learn fundamentals both redhat linux and novell linux is it right i am stuyding B.E CSE i am having linux syllabus

Whether it is right depends on why you want to do it.

The fact that you have to ask implies your reasons aren't sound and you would be better off using a more beginner friendly distribution, such as Ubuntu.

If you have a solid reason to want to learn specifically redhat and novell, rather than generally Linux, you might be best off starting with openSuse
http://www.opensuse.org

Much of what you might learn with Ubuntu is different from what you could later apply to using Redhat or Novell Linux. But almost everything you would learn starting with OpenSuse applies to Novell Linux and more of it (compared to Ubuntu) matches Redhat.

I think there is better beginner support available if you start with Ubuntu, and most of Linux is the same across all distributions. So the benefits of starting with Ubuntu might still apply even if the goal is learning Redhat and Novell.

If the goal is to learn Linux for an IT job, then Redhat and Novell are important to learn, but that still doesn't mean the best path is trying either of them early on. On that path, the second distribution you learn (after starting with either OpenSuse or some beginner friendly distribution) should be Centos. Centos lets you learn everything you need to know about RHEL (Redhat Enterprise Linux) without paying for a license or being constrained by the license (practice installs and other experiments are much easier when no license is involved).

There's not a lot of difference. Linux is Linux: the kernel is the same for everybody. The utilities that run from the command line, like mount or grep, are also the same. What differs are the "housekeeping tools" that each distro has created. To install a new program, Red Hat uses "yum install program" but SUSE uses "zypper install program". But the actual packages in which the programs are delivered are the same, as you can see by their both using the .rpm suffix. The GUI may also vary: SUSE uses KDE by default, while Red Hat uses Gnome. But you can get KDE from Red Hat and Gnome from SUSE.

Of the free versions, I find Fedora and CentOS nicer than OpenSUSE, as the housekeeping tools are more numerous and better written, and they make a better job of KDE than SUSE does of Gnome. I suggest you get OpenSUSE, or one of the customised versions of Fedora (Kororaa or Hanthana), which are easier to set up. See my reviews

i want to learn both redhat and novell

Most of learning Linux is the same across all distributions.

Most of what is different across distributions (different between Ubuntu and Redhat, for example) is still the same between Redhat and Novell.

So you are far from the "both" in your request changing anything significant.

Learning either of them is the same as learning both of them, until you are much further along.
