Linux is an Operating System, that isn't that widely used for desktop machines, but is amongst the most widely used OSs for web servers. It is free of charge, so you will not need to pay any license fees as part of your hosting payments. Linux is furthermore thought of as the most risk-free OS these days and due to the permissions which files have as well as the file types that can be run, virus files that can easily infect a normal computer system will simply not be executed on a Linux-based server. Moreover, the Operating System is 100 % free, so it can be customized with no limits, as a way to suit the needs of the website hosting company and their clients. This suggests that unneeded software packages can be removed to make the OS lighter and a lot quicker, that can directly lead to far better server performance. Lots of Linux machines have the Apache web server set up on them, as this program is also 100 % free, fast and reliable. It's the most popular web server out there and is a part of the LAMP bundle that a great many script applications, including Joomla™ and WordPress, require. LAMP is an abbreviation for Linux, Apache, MySQL and PHP.
