One of the advantages of Fedora is the huge amount of software available for it. Finding, installing, updating, and removing this software can be a daunting task, simply due to the amount of software available. Fortunately, Fedora uses a software management system called RPM Package Manager or simply RPM (formerly RedHat Package Manager). RPM rolls all of the programs, scripts, documentation, configuration files, and data used by a piece of software into a single file called a package. The package also contains metadata describing the package, license, maintainers, and the packages upon which the package depends (for example, a KDE application will need other components of the KDE system to operate). What RPM doesn't provide is dependency resolution: the ability to automatically resolve dependency issues. However, the yum system builds on RPM to provide this capability, automatically searching external repositories to find needed packages and install them automatically.
