Many powerful software applications are available on the Linux operating system. You can find alternatives to most of the popular applications used on other systems.
== GNOME
You can use the Fedora package management system to install applications. Many applications are available from the repository provided by the Fedora project. You can enable other repositories to get additional applications.
In GNOME desktop, Software helps you explore, install and update applications and system extensions.
