Urmpi is a management tool (for packages) developed by Mandriva. You can install different software, delete, or update the distribution. It can also search packages that can be install on many media, such as installation cd, websites, or network share. It acts as a sub-layer to the RPM utility and attempts to automatically manage dependencies.
A "Media" is a server that contains one or more packages (software or libraries). It has the advantage of allowing the installation of software directly via the Internet, without requiring any CDRom. Similarly, it is very convenient for updates.
