Linux is an Operating System, that isn't that common for desktop machines, but is one of the most frequently used OSs for web servers. It's free of charge, so you won't need to pay any license charges as part of your hosting payments. Linux is additionally thought to be the most reliable Operating System nowadays and due to the permissions that files have and also the file types that can be run, virus files which can easily infect a normal PC shall simply not be executed on a Linux-based web server. Furthermore, the Operating System is absolutely free, so it can easily be modified without any limits, in order to suit the needs of the website hosting provider and their clients. This also suggests that unnecessary software packages could be removed to make the OS lighter and much faster, that can directly contribute to significantly better hosting server performance. A large number of Linux machines have the Apache web server set up on them, since this program is also absolutely free, quick and stable. It's the most popular web server out there and is an element of the LAMP bundle that a great many script apps, such as Joomla™ and WordPress, require. LAMP is an abbreviation for Linux, Apache, MySQL and PHP.
