 For example, Linux is used on over 50% of web servers, whereas its desktop market share is about 3.7%.Many Linux distributions provide an installation system akin to that provided with other modern operating systems.On the other hand, some distributions, including Gentoo Linux, provide only the binaries of a basic kernel, compilation tools, and an installer; the installer compiles all the requested software for the specific architecture of the user's computer, using these tools and the provided source code.
