CentOS is a Linux OS based on Red Hat / Fedora Linux. It’s very stable and secure, that’s why we use it on the majority of our servers.
This release is a desktop-operating system for anyone to use on any Intel or AMD based computer. It can be downloaded as an ISO file then either burned to a bootable dvd or installed to a bootable flash drive. Personally, I install it to a virtual drive using Oracle’s Virtual Box.
Alternatively, if you still have an old XP system lying around, you could install it CentOS onto that old system and try it out.
