Linux is an Operating System, that isn't that frequently used for desktop machines, but is one of the most commonly used OSs for servers. It's absolutely free, so you will not have to pay any license charges as part of your web hosting payments. Linux is additionally thought of as the most reliable Operating System nowadays and because of the permissions that files have and the file types that can be run, virus files that can infect a normal personal computer shall simply not be executed on a Linux-based hosting server. Furthermore, the Operating System is freeware, so it can be changed with no constraints, so as to match the requirements of the website hosting provider and their clients. This also means that unneeded software packages can easily be removed to make the Operating system lighter and faster, that may directly result in much better server performance. A lot of Linux machines have the Apache web server set up on them, since this software is also 100 % free, fast and reliable. It is the most popular web server around and is part of the LAMP bundle that many script apps, including Joomla and WordPress, require. LAMP is an abbreviation for Linux, Apache, MySQL and PHP.
