Every desktop or notebook or server is run by an Operating System - the low-level software that interacts with the hardware, including peripheral devices such as a mouse or a printer, together with 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, every single application runs within the parameters established by the OS as well - priority, physical memory, processing time, and so on. This goes for both standard website scripts and server-side software like a media server. If a virtual server is set up on a physical one, there can be two independent Operating Systems, called guest OS and host OS, so that you can set up a different software environment on the very same machine.

Multiple OS in Dedicated Web Hosting

In case you decide to acquire one of our dedicated servers, you'll find three Operating Systems on the order page because we want to give you a wider choice regarding the system environment on the machine as different apps can 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 enjoy a stable and secure Internet hosting service. Based on your choice, you'll also have different Control Panels to choose from. Of course, we can always change the Operating System if the one you have selected at first does not meet the requirements of the software that you would like to run. We can also update the OS on a regular basis in order to keep it as risk-free as possible using our Managed Services upgrade package.
