Each and every notebook or desktop or web server is run by an Operating System - the low-level software that interacts with the computer hardware, including peripherals such as a mouse or a printer, along with any applications that are currently installed on your system. Any program input using a command line or a Graphical User Interface (GUI) is processed by sending an Application Program Interface (API) request to the Operating System. On a server, each and every app runs within the parameters set by the OS as well - priority, physical memory, processing time, etc. This goes for both standard website scripts and server-side software like a media server. If a virtual server is set up on a physical one, there can be two independent Operating Systems, named guest OS and host OS, which means that you will be able to set up a different software environment on a single machine.
Multiple OS in Dedicated Servers
The dedicated server plans that we offer come with three different Operating Systems to pick from. They are all Linux distributions - Ubuntu, CentOS and Debian, and not only do they have no license fees, but they’re also known as the most dependable and secure OSs. We supply three different ones for the reason that each one of them is supported by a different community. The packages which you can add on your web server are different and this could matter if you want to install some piece of software with specific requirements for the hosting environment. In this light, the web hosting Control Panel which you can select for the dedicated server is also determined by the OS that you'll select. You can pick any of the three Operating Systems during the order process, however if needed, we can always install the server anew with an alternative one upon your request. As an optional service that you can add to the package any time, we can update the OS on a regular basis in order to keep it as risk-free as possible.
