Yum Configuration ( Yummy feast)

Yum is software installation tool for Red hat linux and Fedora Linux. It is a complete software management system. Other option is to use up2date utility. yum is designed to use over network/internet. It does not use CDROM to install packages. If you are using fedora you don't have to install it, it is part of fedora itself.

If you don't have yum then download it from project home page http://linux.duke.edu/projects/yum/download.ptml
