Linux is an OS, that isn't that widely used for desktop machines, but is among the most widely used OSs for web servers. It's totally free, so you will not have to pay any license fees as part of your website hosting payments. Linux is furthermore considered to be the most risk-free Operating System out there and thanks to the permissions that files have and also the file types that can be run, virus files which can infect an average 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, as a way to match the requirements of the hosting company and their clients. This also suggests that unneeded software packages could be removed to make the Operating system lighter and swifter, that can directly lead to a lot better server performance. A large number of Linux machines have the Apache web server set up on them, because this piece of software is also free, fast and reliable. It is the most popular web server out there and is a part of the LAMP bundle that lots of script applications, including WordPress and Joomla™, need. LAMP is an abbreviation for Linux, Apache, MySQL and PHP.
