Linux is an Operating System, that is not that common for desktop machines, but is among the most commonly used OSs for servers. It's totally free, so you shall not need to pay any license fees as part of your hosting payments. Linux is additionally thought to be the most secure Operating System these days and because of the permissions which files have and also the file types that can be run, virus files that may infect a regular personal computer will simply not be executed on a Linux-based web server. Moreover, the OS is 100 % free, so it could be altered without any limits, so as to meet the requirements of the web hosting provider and their customers. This also means that unnecessary software packages can easily be removed to make the OS lighter and a lot quicker, that can directly contribute to a lot better server performance. A large number of Linux machines have the Apache web server installed on them, due to the fact that this software is also 100 % free, fast and reliable. It's the most widely used web server available and is an element of the LAMP bundle that lots of script apps, like Joomla™ and WordPress, need. LAMP is an abbreviation for Linux, Apache, MySQL and PHP.
