Linux is everywhere. It powers the Internet as the main operating system behind the Web’s servers, it powers spacecraft, it’s the operating system for the fastest supercomputers in the world and it’s used in smart TVs and mobile devices. Why? Because it’s ultra stable, lightning fast and completely free of charge. However, there’s more to Linux than simply being a free to use operating system. Its unique configuration allows the user to customise and personalise the OS into any form they wish. A Linux user can change their OS look and feel from one day to the next, install thousands of freely available apps and programs and take back control of their computer.
