Linux is an Operating System, that isn't that common for desktop machines, but is among the most commonly used OSs for servers. It's free of charge, so you won't have to pay any license charges as part of your hosting payments. Linux is additionally regarded as being the most risk-free OS nowadays and due to the permissions that files have as well as the file types that can be run, virus files that could infect a normal PC will simply not be executed on a Linux-based server. Additionally, the Operating System is freeware, so it could be altered with no constraints, so that it will meet the requirements of the website hosting company and their clients. This implies that needless software packages may be removed to make the OS lighter and swifter, that can directly contribute to far better hosting server performance. Lots of Linux machines have the Apache web server installed on them, because this software is also totally free, fast and secure. It's the most frequently used web server out there and is a part of the LAMP bundle that many script applications, like Joomla™ and WordPress, need. LAMP is an abbreviation for Linux, Apache, MySQL and PHP.
