RPM Package Manager (RPM) (originally Red Hat Package Manager; now a recursive acronym) is a package management system. The name RPM refers to the following: the .rpm file format, files in the .rpm file format, software packaged in such files, and the package manager program itself. RPM was intended primarily for Linux distributions; the file format is the baseline package format of the Linux Standard Base. Even though it was created for use in Red Hat Linux, RPM is now used in many Linux distributions.
In automobiles, RPM is a way to indicate how hard an engine is working. It is used in conjunction with torque to demonstrate not only the speed of an engine but how much power that engine can produce. For example, a truck engine and a sports car engine may have similar horsepower but different RPM measurements.
