Linux is an Operating System, that isn't that common for desktop machines, but is among the most frequently used OSs for servers. It is totally free, so you won't have to pay any license fees as part of your hosting payments. Linux is furthermore considered to be the most secure Operating System around and because of the permissions that files have and the file types that can be run, virus files which can easily infect a normal computer system shall simply not be executed on a Linux-based hosting server. Furthermore, the Operating System is free, so it can easily be changed with no limitations, in order to match the requirements of the website hosting company and their customers. This also means that unnecessary software packages can be removed to make the OS lighter and much faster, which could directly result in much better server performance. Lots of Linux machines have the Apache web server installed on them, because this software is also free, fast and secure. It is the most widely used web server out there and is part of the LAMP bundle that a lot of script applications, like WordPress and Joomla™, need. LAMP is an abbreviation for Linux, Apache, MySQL and PHP.
