CentOS stands for Community Enterprise Operating System. CentOS is 100% compatible rebuild of the Red Hat Enterprise Linux, in full compliance with Red Hat's redistribution requirements. CentOS is for people who need an enterprise class operating system without the cost of enterprise class support. CentOS is built from Red Hat Enterprise Linux source code and offers a viable alternative for small enterprises that don't need enterprise certifications or support.
CentOS is rock-solid, very stable and highly polished.
The main focus is on long term upgradeability, security, low support costs, and freedom from worms and viruses. It makes an excellent File / Print, Email, Database or Web server, as well as a excellent desktop OS!
Features include SELinux, Xorg, MySQL, Cyrus IMAPD, Gnome and KDE. The supported CPU architectures are: x86_64 (AMD64) - i386 (X86) - IA64 (Itanium). We offer this as a single DVD for ease of shipping and portability. If solid and stable is what you want in a server, give CentOS a try.
