A Linux distribution is an operating system made from a software collection that includes the Linux kernel and often a package management system. They are often obtained from the website of each distribution, which are available for a wide variety of systems ranging from embedded devices and personal computers to servers and powerful supercomputers.
Computer operating systems based on the Linux kernel are used in embedded systems such as consumer electronics, in-vehicle infotainment (IVI), networking equipment, machine control, industrial automation, navigation equipment, spacecraft flight software, and medical instruments in general.
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.
A mobile operating system is an operating system used for smartphones, tablets, smartwatches, smartglasses, or other non-laptop personal mobile computing devices. While computers such as typical/mobile laptops are "mobile", the operating systems used on them are generally not considered mobile, as they were originally designed for desktop computers that historically did not have or need specific mobile features. This line distinguishing mobile and other forms has become blurred in recent years, due to the fact that newer devices have become smaller and more mobile unlike hardware of the past. Key notabilities blurring this line are the introduction of tablet computers, light laptops, and the hybridization of the two in 2-in-1 PCs.
Moblin, short for 'mobile Linux', is a discontinued open source operating system and application stack for Mobile Internet Devices (MIDs), netbooks, nettops and embedded devices.
The Nokia Nseries was a high-end lineup of feature phones, smartphones, and tablets marketed by Nokia Corporation from 2005 to 2011. The Nseries devices commonly supported multiple high-speed wireless technologies at the time, such as 3G, or Wireless LAN. Digital multimedia services, such as music playback, photo/video capture or viewing, gaming or internet services were the central focus of the lineup. The lineup was replaced in 2011 by the Nokia Lumia line as the company's primary smartphone lineup.
The Motorola Droid 4 (XT894) is a smartphone made by Motorola Mobility. It was released with Android 2.3 and can be upgraded to Android 4.1. It was released on Verizon Wireless's network on February 10, 2012. It is the successor to Motorola's Droid 3, and is one of the first smartphones to support GLONASS in addition to GPS.
Mer was a free and open-source software distribution, targeted at hardware vendors to serve as a middleware for Linux kernel-based mobile-oriented operating systems. It is a fork of MeeGo.
Ubuntu Touch is a mobile version of the Ubuntu operating system, being developed by the UBports community. Its user interface is written in Qt, and is designed primarily for touchscreen mobile devices such as smartphones and tablet computers, but the original goal of convergence was intended to bring Ubuntu Touch to laptops, desktops, IOT devices and TVs for a complete unified user experience.
Besides the Linux distributions designed for general-purpose use on desktops and servers, distributions may be specialized for different purposes including computer architecture support, embedded systems, stability, security, localization to a specific region or language, targeting of specific user groups, support for real-time applications, or commitment to a given desktop environment. Furthermore, some distributions deliberately include only free software. As of 2015, over four hundred Linux distributions are actively developed, with about a dozen distributions being most popular for general-purpose use.
Ubuntu is a Debian-based Linux distribution for personal computers, tablets and smartphones, where the Ubuntu Touch edition is used; and also runs network servers, usually with the Ubuntu Server edition, either on physical or virtual servers or with containers, that is with enterprise-class features.
postmarketOS is an operating system primarily for smartphones, based on the Alpine Linux distribution.
Phosh is a graphical user interface designed for mobile and touch-based devices and developed by Purism. It is the default shell used on several mobile Linux operating systems including PureOS, Mobian, and Fedora Phosh. It is also an option on postmarketOS, Manjaro, and openSUSE.
The Librem 5 is a smartphone manufactured by Purism that is part of their Librem line of products. The phone is designed with the goal of using free software whenever possible, and includes PureOS, a Linux operating system, by default. As of 2021, it is the only smartphone recommended by the Free Software Foundation. Like other Librem products, the Librem 5 focuses on privacy and freedom, and includes features like hardware kill switches, and easily-replaceable components. Its name, with a numerical "5", refers to its screen size, and not a release version. After an announcement on 24 August 2017, the distribution of developer kits and limited pre-release models occurred throughout 2019 and most of 2020. The first mass-production version of the Librem 5 was shipped on 18 November 2020.
The PinePhone is a smartphone developed by Hong Kong-based computer manufacturer Pine64, intended to allow the user to have full control over the device. Measures to ensure this are: running mainline Linux-based mobile operating systems, assembling the phone with screws, and simplifying the disassembly for repairs and upgrades. LTE, GPS, Wi-Fi, Bluetooth and both cameras can be physically switched off. The PinePhone ships with the Manjaro Linux operating system using the Plasma Mobile graphic interface, although other distributions can be installed by users.
Comparison of user features of operating systems refers to a comparison of the general user features of major operating systems in a narrative format. It does not encompass a full exhaustive comparison or description of all technical details of all operating systems. It is a comparison of basic roles and the most prominent features. It also includes the most important features of the operating system's origins, historical development, and role.
The PinePhone Pro is a smartphone developed by Hong Kong-based computer manufacturer Pine64. The phone is the successor to the PinePhone released in 2019. The default operating system is Sailfish OS. The device is a developer platform with open hardware specifications but with unfinished software. The target group of the device is free and open-source software developers who will develop the software. The device was first shipped to developers in December 2021, and in February 2022 devices were made available to consumers.
Mobian is a project to port the Debian GNU/Linux distribution running the mainline Linux kernel to smartphones and tablets. The project was announced in 2020. It is available for the PinePhone, PineTab, Librem 5, OnePlus 6/6T and Pocophone F1.
