Linux is an OS, which is not that common for desktop machines, but is one of the most widely used OSs for servers. It is free of charge, so you will not need to pay any license costs as part of your website hosting payments. Linux is furthermore considered to be the most secure OS around and due to the permissions that files have as well as the file types that can be run, virus files that could infect a standard personal computer will simply not be executed on a Linux-based hosting server. Additionally, the OS is freeware, so it can easily be changed without any limits, in order to meet the needs of the web hosting company and their clients. This also means that unnecessary software packages could be removed to make the Operating system lighter and quicker, that can directly lead to a lot better server performance. A large number of Linux machines have the Apache web server installed on them, because this software is also absolutely free, fast and secure. It is the most widely used web server out there and is an element of the LAMP bundle that a great many script applications, including Joomla™ and WordPress, require. LAMP is an abbreviation for Linux, Apache, MySQL and PHP.
