What is YUM?
(Yellowdog Updater Modified) is an open-source command-line as well as graphical-based package management tool for RPM (RedHat Package Manager) based Linux systems.

It was developed and released by Seth Vidal under GPL (General Public License) as an open-source, which means anyone can be allowed to download and access the code to fix bugs and develop customized packages.
It uses numerous third-party repositories to install packages automatically by resolving their dependencies issues.
