Linux is an OS, which is not that frequently used for desktop machines, but is one of the most popular OSs for web servers. It is totally free, so you will not have to pay any license costs as part of your web hosting payments. Linux is also thought of as the most risk-free Operating System these days and due to the permissions that files have and also the file types that can be run, virus files which can easily infect an average computer system will simply not be executed on a Linux-based hosting server. Also, the Operating System is totally free, so it can easily be customized without any limits, so as to suit the requirements of the web hosting company and their clients. This also suggests that unneeded software packages could be removed to make the OS lighter and swifter, that can directly contribute to far 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 free, quick and stable. It's the most widely used web server around and is an element of the LAMP bundle that numerous script apps, such as Joomla™ and WordPress, require. LAMP is an abbreviation for Linux, Apache, MySQL and PHP.
