An Operating System is the low-level software that manages a computer. It takes care of the way the hardware functions, the communication with peripheral devices including a monitor, a printer or a keyboard, the allocation of memory between your applications, along with the prioritization of applications when multiple ones run concurrently. Each and every program that's installed on a desktop or a laptop operates by sending requests to the OS for different services using an application program interface (API). The contact with the OS can be performed through a Graphical User Interface (GUI) or a command line. In the web hosting field, the OS is what commands a hosting server together with any software installed on it, which includes not only website scripts, but, in addition any other application for instance a VOIP or a game server. In case there're virtual machines created, they use a guest OS that runs on the server host OS.
Multiple OS in VPS Web Hosting
If you choose to acquire one of our virtual private server plans, you'll be able to select one of the three Linux distributions which we supply for the Operating System of the servers - CentOS, Ubuntu and Debian. These are among the most preferred and most dependable server OSs available and we offer them so that you have a choice for the software environment of your machine if you intend to install some app with particular requirements regarding the packages that have to be present on the server. We also offer three hosting Control Panels and which one of them you can use will depend on the OS that you've chosen. We leave the chance to change the server Operating System open, so when you want to use software that requires an OS different from the one that's already present, we can always reinstall the VPS. In addition, we can keep the OS up-to-date weekly by installing all of the security updates which may be released.
Multiple OS in Dedicated Servers Hosting
In case you decide to acquire one of our dedicated servers, you will find three Operating Systems on the order page because we want to give you a larger choice with regard to the system environment on your machine as different applications can have certain requirements. CentOS, Ubuntu and Debian feature different modules developed by their large support communities, so you can select any of these OSs and take advantage of a reliable and secure web hosting service. Depending on your selection, you'll also have different Control Panels to choose from. Needless to say, we can always replace the Operating System in case the one you have selected in the beginning does not meet the requirements of the software which you intend to run. We can also update your OS routinely to keep it as secure as possible through our Managed Services upgrade package.
