An Operating System is the software which communicates with the hardware of a PC and works as the intermediary between the installed applications and the hardware, which includes peripherals such as a printer, a mouse or a keyboard. When you run software, it transfers requests to the OS through an API (Application Program Interface) and the contact is done through a command line or a Graphical User Interface (GUI). A lot like a personal computer, web servers also have an Operating System which functions as a host for all the software installed on them, including script applications or server-side software such as a flash server, a VOIP server, etcetera. 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 to the physical server host Operating System.
Multiple OS in Dedicated Hosting
The dedicated servers
that we offer come with as many as 3 different Operating Systems because we want to offer you more flexible solutions that will allow you to install and run any type of web software regardless of its system requirements. The choices are CentOS, Debian and Ubuntu and these three OSs are some of the most dependable and safe ones, not mentioning that they don't have any kind of license fees. All three have a large number of developers that have created countless software packages that you could install and use on your hosting server. We also offer three internet hosting Control Panels and which one you can use will depend on the Operating System that you select when you register. In case you need a different OS later on, it won't be a problem since we can always reinstall your server. With our Managed Services package we can also keep your OS secure by upgrading it every week with all patches that are available for it.
