Angry Qustion re: RHEL 5 update 3 vs Redhat 5.2 version

Hi--I am new to Linux and to this forum. I am confuse how to correctly identify the version and the diff between RHEL 5 update 3 vs RHEL 5.2, What is the .2 is that the release version? what is the update 3 is that the patch version? I also see redhat 8 and 9? That confuse me more.

I would like to use 5.2 for virtualization with CentOS and we have a CD
of RHEL 5 update 3 no Virtualization.

Please clarify th difference.

RHEL 5.2 = RHEL 5 Update 2, RHEL 5.3 = RHEL 5 Update 3.

RHEL = RedHat Enterprise Linux. It is a commercial distribution that requires a paid subscription to RedHat (the company) to get updates via the RedHat Network (RHN). You can get support for it directly from RedHat (the company).

Fedora = Non commercial distribution. The project is supported by RedHat but you can't get support from RedHat directly. You get free updates using the Fedora servers. This is used as a bleeding edge distribution and is essentially an alpha test environment for what may end up in RHEL later. Fedora releases come much more frequently than RHEL and CentOS.

CentOS = Non commercial distribution. The project is NOT supported by RedHat however it is a binary compile of RHEL source so CentOS of the same version as RHEL version would be binarily compatible. Some use RHEL for mission critical (Production) systems and CentOS for test/development purposes.

RedHat (the distribution) = Older Commercial and Non-Commercial distribution. This went up through RedHat 9. At that point RedHat (the company) made RHEL only as a commercial distribution and started renumbering. A short time later they started doing Fedora due to all the folks that were outraged at getting rid of the non-commercial distribution of RedHat.
