Linux is an OS, which is not that popular for desktop machines, but is one of the most popular OSs for web servers. It's free of charge, so you shall not need to pay any license fees as part of your website hosting payments. Linux is additionally thought to be the most risk-free Operating System around 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 will simply not be executed on a Linux-based server. Furthermore, the OS is 100 % free, so it can easily be modified with no constraints, in order to suit the needs of the hosting company and their clients. This suggests that needless software packages can easily be removed to make the OS lighter and a lot quicker, that may directly result in much better server performance. A lot of Linux machines have the Apache web server set up on them, due to the fact that this piece of software is also free, quick and reliable. It's the most frequently used web server available and is a part of the LAMP bundle that lots of script apps, such as Joomla™ and WordPress, require. LAMP is an abbreviation for Linux, Apache, MySQL and PHP.
