Every single PC or web server is run by an Operating System - the low-level program which communicates with the hardware, including peripherals such as a mouse and a printer, and any applications that are installed on your system. Any program input through a command line or a Graphical User Interface (GUI) is processed by sending an Application Program Interface (API) request to the Operating System. On a server, any app runs within the parameters specified by the OS as well - priority, physical memory, processing time, etc. This goes for both standard Internet site scripts and server-side software such as a media server. In case a virtual server is created on a physical one, there can be two separate Operating Systems, called guest OS and host OS, which means that you will be able to set up a different software environment on the very same machine.
Multiple OS in Dedicated Hosting
The dedicated servers that we offer can be set up with three different Operating Systems as we want to offer you more versatile plans that will allow you to install and run any web software irrespective of its system requirements. Your choices are CentOS, Debian and Ubuntu and these 3 OSs are some of the most dependable and risk-free ones, not mentioning that they do not have any license charges. All three have numerous developers that have created a large number of software packages that you could install and use on your server. We also offer three hosting Control Panels and which one you can use depends on the Operating System that you select when you sign up. If you need a different OS afterwards, it will not be a problem because we can always reinstall your server. With our Managed Services package we could also keep your OS secure by upgrading it every week with all patches that are released for it.
