Every single PC or server is run by an Operating System - the low-level program that interacts with the computer hardware, including peripheral devices such as a mouse and a printer, as well as any apps that are installed on the system. Any program input using 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, any application runs within the parameters defined by the OS as well - priority, physical memory, processing time, etcetera. This goes for both standard website scripts and server-side software like a media server. When a virtual server is created on a physical one, there can be two independent Operating Systems, named guest OS and host OS, so you can set up a different software environment on the same machine.

Multiple OS in Dedicated Servers

In case you decide to acquire one of our dedicated servers, you will find three Operating Systems on the registration page since we want to give you a wider choice for the system environment on the machine as different applications could have specific requirements. CentOS, Ubuntu and Debian come with different modules developed by their large support communities, so you can select any of these OSs and benefit from a reliable and secure web hosting service. Depending on your decision, you'll also have different Control Panels to choose from. Needless to say, we can always change the Operating System if the one you have selected in the beginning doesn't meet the requirements of the software that you intend to run. We can also upgrade the OS routinely in order to keep it as risk-free as possible through our Managed Services upgrade package.
