YUM is a tool for managing software packages that is used by several well-known Linux distributions, such as Fedora and CentOS. YUM manages packages in the.rpm file type since it is a front-end for the RPM package manager.
Similar to APT, YUM utilises software repositories, often known as repos, which are unique directories that house collections of software packages. Although users can access remote servers where repositories are normally kept through a network connection, they can also store software packages on their local system.
“YUM” refers for “Yellowdog Updater, Modified,” according to the abbreviation. This moniker refers to YUM’s beginnings as a rebuild of the software updater Yellowdog UPdater (also known as “YUP”) for the now-defunct Linux distribution Yellow Dog. The default package manager in Fedora and Red Hat Enterprise Linux has recently switched to Dandified YUM, sometimes known as “DNF,” a redesign of YUM itself.
