Linux is an OS, which isn't that commonly used for desktop machines, but is among the most popular OSs for web servers. It's free of charge, so you won't have to pay any license fees as part of your web hosting payments. Linux is furthermore regarded as the most risk-free OS nowadays and because of the permissions which files have along with the file types that can be run, virus files that can easily infect an average computer will simply not be executed on a Linux-based web server. In addition, the Operating System is free, so it could be altered without any constraints, so that it will match the requirements of the hosting company and their clients. This also means that unwanted software packages can easily be removed to make the OS lighter and much faster, which can directly result in significantly better hosting server performance. A large number of Linux machines have the Apache web server installed on them, as this program is also free, quick and stable. It is the most widely used web server around and is a part of the LAMP bundle that a great many script apps, like Joomla™ and WordPress, need. LAMP is an abbreviation for Linux, Apache, MySQL and PHP.
