RPM Package Manager (RPM) is a widely used package management system. The .rpm file format is used to distribute software packages, primarily on Linux-based operating systems like Red Hat, Fedora, CentOS, SUSE, and others. RPM packages contain compiled software, along with metadata such as the software's name, version, dependencies, and installation instructions. These packages simplify the process of installing, updating, and removing software. RPM handles dependency resolution, ensuring that all required libraries and other software components are present before installation. This helps prevent conflicts and ensures that the software functions correctly. RPM packages are typically installed using the rpm command-line tool or graphical package managers that build upon it. The format includes a header containing metadata, an archive of the software files, and a signature for verifying the package's authenticity and integrity. RPM is a cornerstone of software management in many Linux distributions, providing a standardized and reliable way to distribute and manage software applications.
