Linux is an Operating System, that isn't that widely used for desktop machines, but is among the most commonly used OSs for servers. It's free of charge, so you will not have to pay any license costs as part of your hosting payments. Linux is additionally thought to be the most risk-free Operating System nowadays and thanks to the permissions that files have and also the file types that can be run, virus files which can easily infect a normal computer will simply not be executed on a Linux-based server. Moreover, the OS is 100 % free, so it can easily be customized without any limitations, so that it will satisfy the requirements of the hosting company and their clients. This also suggests that unwanted software packages can easily be removed to make the OS lighter and much faster, which could directly result in a lot better hosting server performance. A lot of Linux machines have the Apache web server set up on them, because this piece of software is also absolutely free, quick and reliable. It is the most popular web server available and is a part of the LAMP bundle that numerous script apps, including WordPress and Joomla™, require. LAMP is an abbreviation for Linux, Apache, MySQL and PHP.
