An Operating System is the software which interacts with the hardware of a computer system and functions as the intermediary between apps and the hardware, including peripheral devices such as a printer, a mouse or a keyboard. When you run software, it transmits requests to the OS using 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, web hosting servers also feature an Operating System which 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 many others. A virtual machine can be set up 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 OS.
Multiple OS in Dedicated Web Hosting
The dedicated server plans that we offer come with three different Operating Systems to select from. They are all Linux distributions - Ubuntu, CentOS and Debian, and not only do they have no license charges, but they’re also considered to be among the most stable and secure OSs. We provide three different ones because each of them is supported by a separate community. The packages which you could add on your server are different and this may matter if you need to install some piece of software with specific requirements regarding the hosting environment. In this light, the internet hosting Control Panel that you can select for the dedicated server also depends on the OS that you'll choose. You may choose any of the three Operating Systems throughout the order procedure, however if needed, we can always set up the server once again with a different one upon your request. As an optional service that you could add to the package any time, we can update your OS on a regular basis in order to keep it as secure as possible.
