Linux Evolution timeline.

Debian GNU/Linux Debian is a Unix-like computer operating system that is composed entirely of free software, most of which is under the GNU General Public License and packaged by a group of individuals participating in the Debian Project. The Debian stable release branch is the most popular Debian edition for personal computers and network servers, and has been used as a base for many other distributions.

Slackware is a Linux distribution created by Patrick Volkerding in 1993. Originally based on Softlanding Linux System, Slackware has been the basis for many other Linux distributions, most notably the first versions of SUSE Linux distributions, and is the oldest distribution that is still maintained. Slackware aims for design stability and simplicity and to be the most "Unix-like" Linux distribution.

Mandriva Linux (a fusion of the French distribution Mandrakelinux or Mandrake Linux and the Brazilian distribution Conectiva Linux) was a Linux distribution by Mandriva. It used the RPM Package Manager. Each release lifetime was 18 months for base updates (Linux, system software, etc.) and 12 months for desktop updates (window managers, desktop environments, web browsers, etc.). Server products received full updates for at least 5 years after their release.

Arch Linux is a Linux distribution for computers based on x86-64 architectures. The design approach of the development team follows the KISS principle as the general guideline, and focuses on elegance, code correctness, minimalism and simplicity, and expects the user to be willing to make some effort to understand the system's operation. A package manager written specifically for Arch Linux, pacman, is used to install, remove and update software packages.

Linux for PlayStation 2 is a kit released by Sony Computer Entertainment in 2002 that allows the PlayStation 2 console to be used as a personal computer. It included a Linux-based operating system, a USB keyboard and mouse, a VGA adapter, a PS2 network adapter (Ethernet only), and a 40 GB hard disk drive (HDD). An 8 MB memory card is required; it must be formatted during installation, erasing all data previously saved on it, though afterwards the remaining space may be used for savegames.

PCLinuxOS, often shortened to PCLOS, is a Linux distribution, with KDE Plasma Desktop as its default user interface. It is a primarily free software operating system for personal computers aimed at ease of use. It is considered a rolling release. The precursor to PCLinuxOS was a set of RPM packages created to improve successive versions of Mandrake Linux (now Mandriva Linux). These packages were created by Bill Reynolds, a packager better known as Texstar.

Ubuntu is an open source operating system for computers. It is a Linux distribution based on the Debian architecture. It is usually run on personal computers, and is also popular on network servers, usually running the Ubuntu Server variant, with enterprise-class features. Ubuntu runs on the most popular architectures, including Intel, AMD, and ARM-based machines. Ubuntu is also available for tablets and smartphones, with the Ubuntu Touch edition.

Kubuntu is an official flavour of the Ubuntu operating system which uses the KDE Plasma Desktop instead of the Unity graphical environment. As part of the Ubuntu project, Kubuntu uses the same underlying systems. Every package in Kubuntu shares the same repositories as Ubuntu, and it is released regularly on the same schedule as Ubuntu. Kubuntu was sponsored by Canonical Ltd. until 2012, and then directly by Blue Systems.

Sabayon Linux or, is a Gentoo-based Italian Linux distribution created by Fabio Erculiani and the Sabayon development team. Sabayon follows the "out of the box" philosophy, aiming to give the user a wide number of applications ready to use. Sabayon Linux features a rolling release cycle, its own software repository and a package management system called Entropy. Sabayon is available in both x86 and AMD64 distributions and there is support for ARMv7 in development for the BeagleBone.

Android is a mobile operating system developed by Google, based on the Linux kernel and designed primarily for touchscreen mobile devices such as smartphones and tablets. Android's user interface is mainly based on direct manipulation, using touch gestures that loosely correspond to real-world actions, such as swiping, tapping and pinching, to manipulate on-screen objects, along with a virtual
