what is the most popular operating system for servers
Since 2013, devices running Android have been selling more than Windows, iOS and macOS devices combined. Android has therefore become the most popular operating system on smartphones, while iOS is more common on tablets. Most desktop and laptop computers still use Microsoft Windows, while virtually all supercomputers use Linux and have done for over a decade. Among server computers, there is more diversity with Linux and Windows Server most popular, and many fewer mainframe OSs.
