Every personal computer or web server is run by an Operating System - the low-level software which communicates with the computer hardware, including peripheral devices such as a mouse and a printer, as well as any apps that are present 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 web server, each app runs within the parameters established by the OS as well - priority, physical memory, processing time, etc. This is valid for both standard Internet site scripts and server-side software such as a media server. When a virtual server is generated on a physical one, there can be two separate Operating Systems, named guest OS and host OS, so that you will be able to set up a different software environment on the same machine.
Multiple OS in Dedicated Servers
The dedicated server packages 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 fees, but they are also regarded as the most reliable and secure OSs. We supply three different ones for the reason that each one of them is backed by a separate community. The packages that you could add on your server are different and this may matter in case you want to install some piece of software with particular requirements for the hosting environment. In this light, the web hosting Control Panel which you can select for the dedicated server also depends on the Operating System that you'll choose. You may choose any of the three Operating Systems during the order procedure, but if needed, we can always set up the server anew with a different one upon your request. As an additional service that you could add to the package at any time, we can update the OS on a regular basis to keep it as risk-free as possible.
