An Operating System is the software that communicates with the hardware of a computer and is 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 transmits requests to the OS through an API (Application Program Interface) and the interaction is done through a command line or a Graphical User Interface (GUI). Just like a personal computer, hosting servers also use an Operating System that functions as a host for all the software installed on them, including script apps 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 in contrast with the physical server host Operating System.
Multiple OS in Dedicated Servers Hosting
The dedicated servers that we offer can be set up with as many as 3 different Operating Systems because we want to offer you more versatile solutions which will let you install and run any kind of web software irrespective of its system requirements. The choices are CentOS, Debian and Ubuntu and these 3 OSs are among the most stable and risk-free ones, not mentioning that they don't have any license charges. All three have a large number of developers who have created a large number of software packages that you may install and use on your web server. We also offer three hosting Control Panels and which one you can use will depend on the Operating System that you choose when you sign up. If you need some other OS later, it will not be a problem as we can always reinstall your machine. With our Managed Services package we can also keep your OS secure by upgrading it on a weekly basis with any patches that are available for it.
