is the Red Hat package manager that is able to query for information about available packages, fetch packages from repositories, install and uninstall them, and update an entire system to the latest available version.
Yum performs automatic dependency resolution on packages you are updating, installing, or removing, and thus is able to automatically determine, fetch, and install all available dependent packages.
The simplest way to configure a yum repository is to mirror one that already exists. But you do not have to mirror the entire repository, because much of it is built from installation CDs.
In addition, as packages change, or if you combine packages from different mirrors, you may prefer to create yum headers on your own system rather than download them from a remote mirror.
