An Operating System is the software which interacts with the hardware of a PC and serves as the intermediary between all the applications and the hardware, which includes peripheral devices such as a printer, a mouse or a keyboard. When you run an application, it sends requests to the OS through an API (Application Program Interface) and the interaction is done through a command line or a Graphical User Interface (GUI). A lot like a personal computer, web hosting servers also feature an Operating System which acts as a host for any software installed on them, including script apps or server-side software such as a flash server, a VOIP server, and many others. A virtual machine can be created on a physical one, so you could install a guest OS on it and have a different system environment in contrast with the physical server host Operating System.
Multiple OS in Dedicated Servers
In case you decide to obtain one of our dedicated servers, you shall find three Operating Systems on the registration page as we want to give you a larger choice for the system environment on your machine as different apps can have specific requirements. CentOS, Ubuntu and Debian come with different modules developed by their huge support communities, so you can select any of these OSs and enjoy a reliable and secure web hosting service. Depending on your decision, you'll also have different Control Panels to choose from. Of course, we can always change the Operating System if the one you've selected at first does not meet the requirements of the software which you'd like to run. We can also update your OS regularly in order to keep it as risk-free as possible with our Managed Services upgrade package.
