Every desktop or notebook or server is run by an Operating System - the low-level software which communicates with the hardware equipment, including peripherals such as a mouse and a printer, as well as any apps that are present on the system. Any program input through 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, any app runs within the parameters established by the OS as well - priority, physical memory, processing time, and so on. This goes for both standard Internet site scripts and server-side software like a media server. If a virtual server is created on a physical one, there can be two different Operating Systems, called guest OS and host OS, which means that you'll be able to set up a different software environment on the very same machine.
Multiple OS in Dedicated Servers
The dedicated servers that we offer come with three different Operating Systems as we want to offer you more versatile solutions that will enable you to install and run any web software regardless of its system requirements. Your options are CentOS, Debian and Ubuntu and these three OSs are some of the most stable and risk-free ones, not mentioning that they do not have any license charges. All three have lots of developers that have created numerous software packages that you may install and use on your web hosting server. We also offer three web hosting Control Panels and which one you can use depends on the Operating System that you select when you sign up. In case you need a new OS later on, it won't be a problem because we can always reinstall your machine. With our Managed Services package we could also keep your OS secure by upgrading it every week with all patches that are released for it.
