SuSE Linux

A Linux distribution from the SuSE Linux division of Novell. Both consumer and enterprise versions are available, and the distribution includes several user interfaces. SuSE Linux comes with the Yet Another Setup Tool (YaST), which is used to install, configure and maintain the OS, as well as a host of open source applications and utilities.

The Software and System Development Company
SuSE was originally an acronym for "Software und System Entwicklung" (Software and System Development), a German Unix consulting company founded in 1992. In 1994, it released S.u.S.E. Linux 1.0, which was based on Softlanding Linux System (SLS) and Slackware Linux. In German, SuSE is pronounced "zoo-zah," but is often pronounced as "soo-say" by English speakers.

A very popular open source operating system that runs on all major hardware platforms including x86, Itanium, PowerPC, ARM and IBM mainframes. Based on the design principles in the Unix operating system, and often called a "Unix clone", Linux is widely deployed as a server OS and as an embedded OS. For example, Linux runs in most of the servers on the Internet and in countless appliances and consumer electronics (see embedded Linux). In the desktop world, Linux has a small market share; however, Google's Chrome OS may change that status in the future (see Chromebook).

Linux is a multitasking, multiuser operating system that is known for its stability. Although modified by numerous people, its robustness stems from its Unix-like architecture that keeps applications isolated from the core operating system.

Licensed under the GNU General Public License (GPL), Linux is "the" flagship product of the open source community. Numerous groups work on their own flavor of Linux, modifying it for various purposes, and commercial organizations, such as Red Hat and Suse, "distribute" Linux for a fee (see Linux distribution). Linux is also compliant with POSIX, the IEEE compatibility standard (see POSIX). See open source and GNU General Public License.

Not Just One User Interface
Linux employs the X Window rendering system to create the basic window, but it relies on third-party user interfaces to display the borders, buttons, menus, icons and desktop that users manipulate. KDE and GNOME are two of the most popular user interfaces, and both may be included in a Linux distribution. See X Window, KDE and GNOME.

From Unix to Minix to Linux
In 1990, Finnish computer science student Linus Torvalds created the Linux kernel (the heart of the OS). He was inspired by Minix, a classroom teaching tool similar to Unix. Although Torvalds created the kernel, many of the supporting libraries, utilities and applications have come from the GNU Project, which is why Linux is often designated as GNU/Linux. Over the years, a huge number of programmers have contributed. Torvalds maintains the official Linux kernel, and Linux is his registered trademark.

Linux Is Really "Lee-Nooks"
In Finland, they say "lee-nooks" because Linus is pronounced "lee-noose." Since the English pronounce Linus as "line-iss," some call it "line-icks." More common is "lynn-icks." See embedded Linux, Minix, Ubuntu, SuSE Linux, UnitedLinux, CoreOS, OS virtualization, GNU, open source, Linux Foundation, Trinux, SCO and Red Hat.

Linux in Your TV
MontaVista Linux provides the user interface in this Sony TV. Increasingly, people are finding a GPL open source license with the electronics they purchase, which covers the legal use of the software running in the device. See GNU General Public License.

The Linux Logo
