Linux works on almost every kind of computer in existance, and provides a robust platform for a wide variety of applications. Unlike most Operating Systems Linux is free in almost all respects. One can download it off the internet at no charge, pass on copies to friends, and even modify its internals. This 'freeness' has been one of the most critical reasons for its success, and is turning heads in the industry and mainstream media. In fact, Linux takes first place when it comes to the support of diverse hardware.
Diversity is a key word when talking about Linux.
Not only does Linux run on very different hardware, but it can talk to a wide variety of networks. GNU is also responsible for the license that Linux is distributed under. Even though Linux is really just a kernel, most peopleLinux costs nothing. Although Linux is available at no cost to anyone with the inclination to download it, the key idea has to do with freedom of use rather than 'freeness' with regard to price. This license allows users to sell, copy or even change Linux to suit their own needs and agendas.
