Fedora OS

Fedora is an operating system based on Linux kernel and GNU programs, developed by the community-supported Fedora Project and sponsored by Red Hat.Fedora contains software distributed under a free and open-source license and aims to be on the leading edge of such technologies.Fedora Core 1 was the first version of Fedora and was released on November 6, 2003.If anyone has experience using other linux distributions like ubuntu then running Fedora shouldn't be a problem for them .


Features

Fedora has a reputation for focusing on innovation, integrating new technologies early on and working closely with Linux communities.[1] Making changes upstream instead of specifically in Fedora ensures that the changes are available to all Linux distributions.

Fedora has a relatively short life cycle: version is supported only until 1 month after new version is released and with approximately 6 months between most versions, meaning a version of Fedora is usually supported for at least 13 months, possibly longer.[2] Fedora users can upgrade from version to version without reinstalling.[3][4]

The default desktop environment in Fedora is GNOME and the default user interface is the GNOME Shell. Other desktop environments are available too and can be installed.[5][6]

Package management

Fedora uses the RPM Package Manager package management system. Flatpak is also supported by default, and support for Ubuntu's Snappy package manager format can also be added. Fedora uses Delta RPM when updating installed packages to provide Delta update. A Delta RPM contains the difference between an old and new version of a package. This means that only the changes between the installed package and the new one are downloaded reducing network traffic and bandwidth consumption.

Security

Security is very important in Fedora with one specific security feature being Security-Enhanced Linux, which implements a variety of security policies, including mandatory access controls, which Fedora adopted early on.[7] Fedora provides hardening wrapper, and does hardening for all of its packages by using compiler features such as position-independent executable (PIE).[8]

Software

Fedora comes installed with a wide range of software such as LibreOffice and Firefox. Additional software is available from the Software repository and can be installed using the package manager or GNOME Software.


Additionally, extra repositories can be added to the system, so that software not available in Fedora can be installed more readily.[9]Template:Rp Software that is not available via official Fedora repositories, either because it doesn't meet Fedora's definition of free software or because its distribution may violate US law, can be installed using third-party repositories. Popular third-party repositories include RPM Fusion free and non-free repositories. Fedora also provides users with an easy-to-use build system for creating their own repositories called Copr.[10]

Editions

Beginning with Fedora version 21,[11] it is available as three distinct primary editions:

  • Fedora Workstation – It targets users who want a reliable, user-friendly, and powerful operating system for their laptop or desktop computer. It comes with GNOME by default but other desktops can be installed or can be directly installed as Spins.
  • Fedora Server – Its target usage is for servers, and it includes the latest data center technologies. This edition doesn't come with a desktop environment, but one can be installed.
  • Fedora Cloud – It provides a minimal image of Fedora which includes just the bare essentials. It is meant for deployment in cloud computing. It also provides Fedora Atomic Host images which are optimized minimal images for container uses.

A Live USB drive can be created using Fedora Live USB creator or the dd command.[9]Template:Rp It allows the users to try Fedora without making changes to the hard disk.

Spins

Similar to Debian blends, the Fedora Project also distributes custom variations of Fedora called Fedora spins or editions.[12] These are built with specific sets of software packages, offering alternative desktop environments or targeting specific interests such as gaming, security, design, education,[13] robotics,[14][15] and scientific computing[16] (that includes SciPy, Octave, Kile, Xfig and Inkscape). Fedora spins are developed by several Fedora special interest groups.[12] Fedora also provides a Fedora Atomic Host image for Project Atomic, which is Red Hat's solution for deploying Docker-based containerized applications.[17]

Architectures

Intel i686, AMD x86-64 and ARM-hfp are the primary architectures supported by Fedora.[18] Pidora[19] and FedBerry[20] are specialized Fedora distributions for the Raspberry Pi. As of release 25, Fedora also supports ARM AArch64, IBM Power64, IBM Power64le, IBM Z, MIPS-64el, MIPS-el and RISC-V as secondary architectures.
