Where to obtain Linux

OK so obtaining Linux is not a difficult job as the different Linux distributions have their own websites. Well different distributions varies in sizes, some available in CD's and some available in DVD's. I suggest you to download the Red Hat Enterprise Linux from Red Hat's official site "www.redhat.com/downloads" or choose the CentsOs from "  http://www.centos.org/modules/tinycontent/index.php?id=15". If you are aware of Torrents then its great just download it from there. Please choose the DVD versions for these distributions instead of CD's and once the ISO is downloaded burn it with any of the DVD burning software and Gets ready for the installation.
