6. OS Definition:

6.1. Different categories of computers use a wide variety of operating systems, and the usage share varies enormously from one category to another. For instance, desktop and laptop computers used for web browsing are dominated by Microsoft Windows, which has a usage share estimated to be around 90%, while Linux is quoted to have a share around 1%.[1] In contrast, the complete reverse is true for the fastest supercomputers.
