Fedora
Fedora Linux is a Linux distribution developed by the community-supported Fedora Project which is sponsored primarily by Red Hat, a subsidiary of IBM, with additional support from other companies. Fedora contains software distributed under various free and open-source licenses and aims to be on the leading edge of free technologies. Fedora is the upstream source of the commercial Red Hat Enterprise Linux distribution. Fedora Linux is a fork of Red Hat Linux since RHL was discontinued in 2003.
Fedora — its default desktop environment (GNOME 41)
Since the release of Fedora 30, five different editions are currently available: Workstation, focused on the personal computer, Server for servers, CoreOS, focused on cloud computing, Silverblue, focused on an immutable desktop specialized to container-based workflows and IoT, focused on IoT devices. As of February 2016, Fedora Linux has an estimated 1.2 million users, including Linus Torvalds (as of May 2020), creator of the Linux kernel.
Fedora has a reputation for focusing on innovation, integrating new technologies early on and working closely with upstream Linux communities. Making changes upstream instead of specifically for Fedora Linux ensures that the changes are available to all Linux distributions.
