The Yellowdog Updater Modified (YUM) is a free and open-source command-line package-management utility for computers running the Linux operating system using the RPM Package Manager.

DNF (abbreviation for Dandified YUM) [7] [8] [9] is a package manager for Red Hat-based Linux distributions and derivatives. DNF was introduced in Fedora 18 in 2013 as a replacement for yum; [10] it has been the default package manager since Fedora 22 in 2015 [11] and Red Hat Enterprise Linux 8 [when?] [12] and is also an alternative package manager for Mageia.

Upon installation, metadata is stored in a local package database. Package managers typically maintain a database of software dependencies and version information to prevent software mismatches and missing prerequisites. They work closely with software repositories, binary repository managers, and app stores.
Spec files end in the ".spec" suffix and contain the package name, version, RPM revision number, steps to build, install, and clean a package, and a changelog. Multiple packages can be built from a single RPM spec file, if desired. RPM packages are created from RPM spec files using the rpmbuild tool.
A software repository, or repo for short, is a storage location for software packages. Often a table of contents is also stored, along with metadata. A software repository is typically managed by source or version control, or repository managers. Package managers allow automatically installing and updating repositories, sometimes called "packages".
The aim of this package manager is to achieve a high install and update speed, which it does by writing new data directly in-place into the operating system's file system, rather than employing caching or compression. [15] In 2014, Alpine Linux switched from uClibc to musl as its C standard library. [18]
