Each and every personal computer or web server is run by an Operating System - the low-level software that communicates with the hardware, including peripheral devices such as a mouse and a printer, and any applications that are currently installed on the 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 OS. On a server, each app runs within the parameters established by the OS as well - priority, physical memory, processing time, etc. This is valid for both standard Internet site scripts and server-side software such as a media server. When a virtual server is set up on a physical one, there can be two different Operating Systems, named guest OS and host OS, so you will be able to set up a different software environment on a single machine.

Multiple OS in Dedicated Servers

In case you decide to get one of our dedicated servers, you shall find three Operating Systems on the registration page since we want to give you a larger choice regarding the system environment on the server as different applications may have particular requirements. CentOS, Ubuntu and Debian include different modules developed by their large support communities, so you can select each of these OSs and take advantage of a reliable and safe Internet hosting service. Depending on your decision, you will also have different Control Panels to choose from. Needless to say, we can always change the Operating System if the one you've selected in the beginning does not meet the requirements of the software which you'd like to run. We can also update the OS on a regular basis to keep it as secure as possible with our Managed Services upgrade package.
