An Operating System is the software that interacts with the hardware of a computer system and functions as the intermediary between all the applications and the hardware, including peripherals such as a printer, a mouse or a keyboard. When you run an application, it transfers requests to the OS through an API (Application Program Interface) and the interaction is done via a command line or a Graphical User Interface (GUI). Just like a personal computer, hosting servers also use an Operating System that serves as a host for the software installed on them, including script applications or server-side software such as a flash server, a VOIP server, etcetera. A virtual machine can be generated on a physical one, so you will be able to install a guest OS on it and have a different system environment compared to the physical server host OS.
Multiple OS in Dedicated Web Hosting
We offer three Operating Systems with our dedicated server
solutions - CentOS, Ubuntu and Debian. They're all different Linux distributions and we offer them not only because they are completely free and they will not increase the price of your new web server, but also because they are very secure and stable. Each of them is backed up by a large community of developers, so you will be able to choose from a large number software packages that you may install on your server in case the application that you intend to use has specific requirements. The Operating System will also determine what internet hosting Control Panel you can use since the Control Panels that we offer run on particular OSs only and since we would like to provide you with as much freedom as possible, we offer a couple of OSs and multiple Control Panels. In case you choose a server with a given Operating System, we can change it upon request in case it turns out that you'll need another one. We can also keep the OS updated on a weekly basis as a part of our optional Managed Services upgrade.
