The Yellowdog UPDATER, Modified (yum) is an open-source command-line package-management utility for Linux operating systems using the RPM Package Manager. Though yum has a command-line interface, several other tools provide graphical USER interfaces to yum FUNCTIONALITY. Yum allows automatic updates, package and dependency management, on RPM-based distributions. Like the Advanced Packaging Tool (APT) from Debian, yum works with software REPOSITORIES (collections of packages), which can be accessed locally or over a network connection.

Advantages of Yum Server:

• Automatic resolution of software dependencies. If a package installation or upgrade request is made and requires the installation or upgrade of additional packages, YUM can list these dependencies and prompt the user to install or upgrade them.
• Command-line and graphical versions. The command-line version can be run on a system with a minimal number of software packages. The graphical versions offer ease-of-use and a user-friendly graphical interface to software management.
• Multiple software LOCATIONS at one time. YUM can be configured to look for software packages in more than one location at a time.
