An Operating System is the low-level software that manages a PC. It controls the way the hardware operates, the communication with peripheral devices including a monitor, a printer or a keyboard, the allocation of memory between all the applications, along with the prioritization of applications when several run simultaneously. Each and every program that is installed on a notebook or a desktop operates by sending requests to the OS for different services by using an application program interface (API). The communication with the OS is possible via a Graphical User Interface (GUI) or a command line. In the web hosting field, the OS is what commands a web hosting server as well as all the software installed on it, which includes not only website scripts, but also any other application such as a VOIP or a game server. If there're virtual machines created, they employ a guest OS which is run on the server host OS.
Multiple OS in Dedicated Web Hosting
If you decide to buy one of our dedicated servers, you shall find three Operating Systems on the registration page because we want to give you a wider choice for the system environment on your machine as different apps may have specific requirements. CentOS, Ubuntu and Debian feature different modules developed by their large support communities, so you can select any of these OSs and enjoy a reliable and secure hosting service. Depending on your decision, you will also have different Control Panels to choose from. Of course, we can always replace the Operating System in case the one you've selected at first doesn't meet the requirements of the software which you want to run. We can also upgrade your OS routinely in order to keep it as secure as possible through our Managed Services upgrade package.
