A Linux distribution is an operating system made from a software collection that includes the Linux kernel and often a package management system. Linux users usually obtain their operating system by downloading one of the Linux distributions, which are available for a wide variety of systems ranging from embedded devices and personal computers to powerful supercomputers.
Knoppix, stylized KNOPPIX, is an operating system based on Debian designed to be run directly from a CD / DVD or a USB flash drive. It was first released in 2000 by German Linux consultant Klaus Knopper, and was one of the first popular live distributions. Knoppix is loaded from the removable medium and decompressed into a RAM drive. The decompression is transparent and on-the-fly.
A live CD is a complete bootable computer installation including operating system which runs directly from a CD-ROM or similar storage device into a computer's memory, rather than loading from a hard disk drive. A live CD allows users to run an operating system for any purpose without installing it or making any changes to the computer's configuration. Live CDs can run on a computer without secondary storage, such as a hard disk drive, or with a corrupted hard disk drive or file system, allowing data recovery.
Damn Small Linux (DSL) is a computer operating system for the x86 family of personal computers. It is free and open-source software under the terms of the GNU GPL and other free and open-source licenses. It was designed to run graphical user interface applications on older PC hardware, for example, machines with 486 and early Pentium microprocessors and very little random-access memory (RAM). DSL is a live CD with a size of 50 megabytes (MB). What originally began as an experiment to see how much software could fit in 50 MB eventually became a full Linux distribution. It can be installed on storage media with small capacities, like bootable business cards, USB flash drives, various memory cards, and Zip drives.
Slax is a LiveCD Linux distribution developed by Tomáš Matějíček and based on upstream customizable Linux distributions. Packages can be added by apt package manager or can be prepared as modules. The tagline for Slax refers to itself as "your pocket operating system".
A light-weight Linux distribution is one that uses lower memory and/or has less processor-speed requirements than a more "feature-rich" Linux distribution. The lower demands on hardware ideally result in a more responsive machine, and/or allow devices with fewer system resources to be used productively. The lower memory and/or processor-speed requirements are achieved by avoiding software bloat, i.e. by leaving out features that are perceived to have little or no practical use or advantage, or for which there is no or low demand.
PCLinuxOS, often shortened to PCLOS, is a rolling release Linux distribution for x86-64 computers, with KDE Plasma, MATE, and XFCE as its default user interfaces. It is a primarily FOSS operating system for personal computers aimed at ease of use.
Puppy Linux is a family of light-weight Linux distributions that focus on ease of use and minimal memory footprint. The entire system can be run from random-access memory (RAM) with current versions generally taking up about 600 MB (64-bit), 300 MB (32-bit), allowing the boot medium to be removed after the operating system has started. Applications such as AbiWord, Gnumeric and MPlayer are included, along with a choice of lightweight web browsers and a utility for downloading other packages. The distribution was originally developed by Barry Kauler and other members of the community, until Kauler retired in 2013. The tool Woof can build a Puppy Linux distribution from the binary packages of other Linux distributions.
Technical variations of Linux distributions include support for different hardware devices and systems or software package configurations. Organizational differences may be motivated by historical reasons. Other criteria include security, including how quickly security upgrades are available; ease of package management; and number of packages available.
Finnix is a Debian-based Live CD operating system, developed by Ryan Finnie and intended for system administrators for tasks such as filesystem recovery, network monitoring and OS installation. Finnix is a relatively small distribution, with an ISO download size of approximately 100 MiB, and is available for the x86 and PowerPC architectures, and paravirtualized systems. Finnix can be run off a bootable CD, a USB flash drive, a hard drive, or network boot (PXE).
SliTaz GNU/Linux is a lightweight Linux distribution, community-based, suitable for use on older hardware and as a Live CD or Live USB. SliTaz stands for "Simple, Light, Incredible, Temporary Autonomous Zone" according to the boot screen.
Grml is a Linux distribution based on Debian. It is designed to run mainly from a live CD, but can be made to run from a USB flash drive. Grml aims to be well-suited to system administrators (sysadmin) and other users of text tools. It includes an X Window System server and a few minimalist window managers such as wmii, Fluxbox, and openbox to use the graphical programs like Mozilla Firefox which are included in the distribution.
Aurora is a discontinued operating system for netbooks. The latest version is based on Ubuntu, though newer versions were planned to be based on Debian Unstable. Eeebuntu was designed originally for the Asus Eee PC line of netbooks.
Peppermint OS is a Linux distribution based on Debian and Devuan Stable, and formerly based on Ubuntu. It uses the Xfce desktop environment. It aims to provide a familiar environment for newcomers to Linux, which requires relatively low hardware resources to run.
Devuan is a fork of the Debian Linux distribution that uses sysvinit, runit or OpenRC instead of systemd. Devuan aims to avoid "lock-in" by projects like systemd and aims to maintain compatibility with other init systems to avoid detaching Linux from other Unix systems.
MX Linux is a Linux distribution based on Debian stable and using core antiX components, with additional software created or packaged by the MX community. The development of MX Linux is a collaborative effort between the antiX and former MEPIS communities. The MX name comes from the "M" in MEPIS and the "X" in antiX — an acknowledgment of their roots. The community's stated goal is to produce "a family of operating systems that are designed to combine elegant and efficient desktops with high stability and solid performance".
LinuxConsole is a Linux distribution independently developed by Yann Le Doaré. LinuxConsole should be written as a single word, and the use of the word "console" in the name does not relate to Linux's system console mode but instead represents its aim of providing a system more simple to use similar to that of a gaming console. This distro is built from scratch by developers from France, and has support for multiple languages. It is not based on any other Linux distribution and primarily features being lightweight and easily accessible. LinuxConsole can function as a live CD or live USB. It can also be installed as a complete operating system.
