Linux is an Operating System, which isn't that popular for desktop machines, but is amongst the most popular OSs for servers. It is absolutely free, so you shall not need to pay any license charges as part of your website hosting payments. Linux is furthermore regarded as the most risk-free Operating System nowadays and because of the permissions that files have and also the file types that can be run, virus files which could infect an average computer will simply not be executed on a Linux-based server. Also, the Operating System is absolutely free, so it can be altered without any limitations, in order to meet the needs of the hosting provider and their customers. This means that unnecessary software packages may be removed to make the Operating system lighter and much faster, which can directly contribute to significantly better server performance. Lots of Linux machines have the Apache web server set up on them, due to the fact that this program is also totally free, fast and stable. It's the most popular web server available and is part of the LAMP bundle that numerous script apps, including Joomla™ and WordPress, need. LAMP is an abbreviation for Linux, Apache, MySQL and PHP.
