Shamelessly stolen from Wikipedia and the Yum page (thanks Shodan) until I can legitimately write this.
DNF or Dandified Yum is the next generation version of the Yellowdog Updater, Modified (yum), a package manager for RPM-based distributions. DNF was introduced in Fedora 18 and it is a default package manager for Fedora since the version 22. Perceived deficiencies of yum which DNF is intended to address include poor performance, high memory usage, and the slowness of its iterative dependency resolution. DNF uses libsolv, an external dependency resolver.
'DNF is a package manager used to manage RPM packages. It's used in pretty much all Linux distros based around the RPM package format, and is especially notable for being used in Red Hat distributions as well as in Fedora. It was introduced to Fedora in version 18, and outed the deprecated Yum in Fedora 22.
It is much better than Yum was, because it's rewrite addressed yum's worst problems, such as bad performance and high memory usage.
