Linux is often considered an excellent, low-cost alternative to other more expensive operating systems. Linux is being further developed by a loosely knit team of talented programmers working from all over the world. Linux works on almost every kind of computer in existance, and provides a robust platform for a wide variety of applications. 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.
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 people associate it with a complete package. Linux has an official mascot, the Linux Penguin, called Tux, which was selected by Linus Torvalds to represent the image he associates with the operating system he created. There are several Linux Distributions for you to choose from.
