An Operating System is the software that interacts with the hardware of a computer and serves as the intermediary between the installed applications and the hardware, including peripherals 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 communication is done via a command line or a Graphical User Interface (GUI). A lot like a personal computer, web hosting servers also have an Operating System that acts as a host for any software installed on them, which includes script applications or server-side software such as a flash server, a VOIP server, and so on. A virtual machine can be generated on a physical one, so you'll 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 Hosting
The dedicated server plans that we offer come with three different Operating Systems to pick from. They are all Linux release - Ubuntu, CentOS and Debian, and not only do they have no license charges, but they’re also regarded as the most stable and secure OSs. We offer three different ones since each one of them is supported by a separate community. The packages that you could add on your server are different and this may matter if you want to install some piece of software with specific requirements for the hosting environment. In this light, the hosting Control Panel that you can select for the dedicated server also depends on the Operating System that you will choose. You can pick any of the three Operating Systems during the order process, yet if necessary, we can always install the server once again with an alternative one upon your request. As an additional service that you could add to the plan at any time, we can update your OS on a regular basis in order to keep it as risk-free as possible.
