Linux is a UNIX-like 32-bit operating system that runs on a variety of platforms, including Intel, SPARC, PowerPC, and DEC Alpha processors, as well as multiprocessing systems. The operating system is essentially free and you can download it from the Web. You can buy fully supported commercial versions from Red Hat, Caldera Systems, and other companies.
Linux is a "user-developed" product, meaning that many of its components and drivers have been developed by users around the world who ran the operating system for their own use. The original operating system was developed by Linus Torvalds as a college project. It is now well supported and gaining ground as a respectable operating system despite its homegrown roots. The operating system is used by many Web site developers and is now available as an embedded system, either as a small software kernel or burned into a chip.
Anyone planning to use Linux for production use should first make sure that the applications they need to use run on the operating system, and that appropriate drivers are available to support hardware and software. You can check the Web site listed on the related entries page for more information. Here are some basic Linux facts:
