[Linux] RPM Repositories

[Frost Jack]

Noob question:

Can someone explain or point me somewhere where so I
can get educated on repositories. I've read up on
installing (RPMs) but not familiar with how
repositories work. The distro im using now is RHEL5
and CentOS 5. So here are some of my questions: Are
there dedicated repositories to each distro? And if
yes am I locked into the one my distro uses? How do I
find out the url or server name for  a repository? If
anyone has any other tidbit of info I should know
please share. thank you for any input.

Regards,
Matt
