Linux is an OS, that is not that common for desktop machines, but is one of the most frequently used OSs for servers. It is 100 % free, so you shall not need to pay any license costs as part of your hosting payments. Linux is additionally regarded as the most secure Operating System available and due to the permissions which files have along with the file types that can be run, virus files which can easily infect a regular PC will simply not be executed on a Linux-based web server. Furthermore, the Operating System is totally free, so it can be changed without any limitations, so that it will satisfy the needs of the website hosting company and their clients. This also suggests that unneeded software packages can be removed to make the OS lighter and swifter, which can directly lead to significantly better server performance. Lots of Linux machines have the Apache web server set up on them, due to the fact that this application is also totally free, quick and secure. It's the most commonly used web server out there and is part of the LAMP bundle that a great many script apps, like WordPress and Joomla™, require. LAMP is an abbreviation for Linux, Apache, MySQL and PHP.
