Every single personal computer or server is run by an Operating System - the low-level software which communicates with the hardware, including peripherals such as a mouse and a printer, and any applications that are 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 OS. On a server, any application runs within the parameters defined by the OS as well - priority, physical memory, processing time, and so on. This is valid for both standard Internet site scripts and server-side software like a media server. In case a virtual server is created on a physical one, there can be two independent Operating Systems, called guest OS and host OS, which means that you can set up a different software environment on the same machine.
Multiple OS in Dedicated Servers
The dedicated servers that we offer can be installed with three different Operating Systems since we want to offer you more flexible packages that will permit you to install and run any kind of web software regardless of its system requirements. Your options are CentOS, Debian and Ubuntu and these three OSs are among the most reliable and secure ones, not mentioning that they do not have any kind of license charges. All three have lots of developers who have created countless software packages that you may install and use on your hosting server. We also offer three hosting Control Panels and which one you can use depends on the Operating System that you select when you register. If you need a different OS later, it won't be a problem as we can always reinstall your server. With our Managed Services package we could also keep your OS secure by upgrading it every week with any patches that are available for it.
