CentOS users as a group are a community of open source contributors and users. Typical CentOS users are organizations and individuals that do not need strong commercial support in order to achieve successful operation.
CentOS : Community ENTerprise Operating System
CentOS 2, 3, 4 and 5 are built from publicly available open source SRPMS provided by a prominent North American Enterprise Linux vendor. CentOS conforms fully with the upstream vendors redistribution policies and aims to be 100% binary compatible. (CentOS mainly changes packages to remove upstream vendor branding and artwork).

ftp://ftp.redhat.com/pub/redhat/linux/enterprise/5Client/en/os/SRPMS
ftp://ftp.redhat.com/pub/redhat/linux/enterprise/5Server/en/os/SRPMS
Before building the OS, non-free packages are altered. Non-free packages would include those encumbered with a non-redistributable copyright or trademark.
CentOS-5 supports the x86 and x86_64 (AMD64 and Intel EMT64) architectures. Support for the ia64, ppc, and sparc architectures is in progress. Updates are distributed via YUM repositories.
