An Operating System is the software which interacts with the hardware of a computer and is the intermediary between applications and the hardware, which includes peripheral devices such as a printer, a mouse or a keyboard. When you run an app, it transfers requests to the OS using an API (Application Program Interface) and the contact is done through a command line or a Graphical User Interface (GUI). Identical to a personal computer, hosting servers also use an Operating System that functions as a host for all of the software installed on them, which includes script apps or server-side software such as a flash server, a VOIP server, and so on. A virtual machine can be created on a physical one, so it is possible to install a guest OS on it and have a different system environment in contrast with the physical server host OS.
Multiple OS in Dedicated Servers
We offer three Operating Systems with our dedicated server plans - CentOS, Ubuntu and Debian. They're all different Linux distributions and we offer them not only because they are absolutely free and they will not increase the low price of your new web hosting server, but also because they are exceptionally secure and stable. Each one of them is supported by a huge community of web developers, so you will be able to choose from a myriad of software packages that you may install on your server in case the application that you would like to use has certain requirements. The Operating System will also determine what web hosting Control Panel you can use as the Control Panels that we offer run on specific OSs only and because 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 OS, we will change it upon request in case it turns out that you'll need a different one. We can also keep the OS updated weekly as part of the useful Managed Services upgrade.
