Linux is an OS, that is not that frequently used for desktop machines, but is amongst the most widely used OSs for web servers. It's 100 % free, so you won't have to pay any license fees as part of your website hosting payments. Linux is additionally thought to be the most risk-free OS available and because of the permissions which files have along with the file types that can be run, virus files which can infect a regular computer will simply not be executed on a Linux-based web server. In addition, the OS is freeware, so it could be modified without any constraints, so that it will meet the needs of the hosting provider and their clients. This suggests that unneeded software packages could be removed to make the Operating system lighter and much faster, which can directly result in far better server performance. A lot of Linux machines have the Apache web server installed on them, because this software is also free, fast and secure. It's the most frequently used web server available and is part of the LAMP bundle that a lot of script apps, including Joomla™ and WordPress, need. LAMP is an abbreviation for Linux, Apache, MySQL and PHP.
