Linux is an OS, which isn't that frequently used for desktop machines, but is among the most popular OSs for web servers. It's 100 % free, so you shall not have to pay any license fees as part of your hosting payments. Linux is furthermore considered to be the most reliable OS these days and because of the permissions which files have along with the file types that can be run, virus files which can infect a standard PC will simply not be executed on a Linux-based web server. Also, the Operating System is freeware, so it can be modified with no constraints, in order to meet the requirements of the hosting provider and their clients. This also means that unneeded software packages could be removed to make the Operating system lighter and faster, which can directly lead to a lot better hosting server performance. Lots of Linux machines have the Apache web server installed on them, since this piece of software is also absolutely free, quick and secure. It is the most commonly used web server out there and is part of the LAMP bundle that lots of script apps, such as Joomla™ and WordPress, need. LAMP is an abbreviation for Linux, Apache, MySQL and PHP.
