By regularly running yum update, you can ensure that your system is up-to-date and secure. Yum can also be used to manage system updates, including security updates and bug fixes. Unlike it’s Debian cousin, which uses various commands for package management, yum can perform all package operations by itself. These repositories contain metadata about the packages, such as version numbers and dependencies, which yum uses to resolve dependencies and ensure that the correct versions of packages are installed. It uses repositories, which are online collections of packages that can be installed on your system. Yum makes it easy to search for, install, remove, and update packages and dependencies, as well as handle any conflicts that may arise. It stands for 'Yellowdog Updater, Modified' and was originally developed by Yellowdog Linux as a way to easily manage packages on their distribution.

Yum is a command-line package manager for RPM-based Linux systems, such as Red Hat Enterprise Linux, CentOS, Fedora, and Oracle Linux.
