In Linux distributions, almost every distribution has its own package management system. Common are the dpkg of the deb package and its front-end apt (for debian, Ubuntu, etc.). Rpm and its front end yum (for RedHat series systems).

RPM, the full name RPM Package Manager, is a package management system from Red Hat that is now widely available in various distributions.

The RRM package is a package file that is compiled and packaged by the program source code. The package contains the software binary, configuration files, help manuals, library files, and header files. RPM package structure shown below:
