Each and every PC or web server is run by an Operating System - the low-level software that interacts with the hardware equipment, including peripherals such as a mouse and a printer, along 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, any app runs within the parameters set by the OS as well - priority, physical memory, processing time, etcetera. This goes for both standard site scripts and server-side software like a media server. If a virtual server is generated on a physical one, there can be two independent Operating Systems, named guest OS and host OS, so you will be able to set up a different software environment on the very same machine.

Multiple OS in Dedicated Servers

If you decide to acquire one of our dedicated servers, you'll find three Operating Systems on the registration page as we want to give you a wider choice regarding the system environment on the machine as different applications may have specific requirements. CentOS, Ubuntu and Debian contain different modules developed by their large support communities, so you can select any of these OSs and enjoy a stable and risk-free Internet hosting service. Based on your decision, you will also have different Control Panels to choose from. Needless to say, we can always replace the Operating System in case the one you have selected initially does not meet the requirements of the software which you want to run. We can also upgrade the OS regularly to keep it as secure as possible using our Managed Services upgrade package.
