what is rpm linux

RPM stands for Red Hat Package Manager, which is a free and open-source package management system used in Linux distributions such as Fedora, CentOS, OpenSUSE, OpenMandriva, and Oracle Linux. RPM is used for installing, uninstalling, and managing software packages in Linux. It was designed to be used in Red Hat Linux, but now it is widely used in other Linux distributions. RPM files are binary with the compiled version of the software, and most RPM files are pre-compiled software ready for direct installation. RPM is known for enhanced security, and when packages are installed using RPM, it writes records into a database that keeps track of detailed information about the packages. RPM allows intelligent, fully-automated, in-place upgrades of the system, and configuration files in packages are preserved across upgrades, so customizations are not lost. RPM is distributed under the terms of the GPL. To use RPM, you need to have a package you want to install already, and then you can use the RPM commands to install, uninstall, and upgrade the packages.
