An Operating System is the basic software that controls a computer. It takes care of how your hardware behaves, the communication with peripheral devices including a monitor, a printer or a keyboard, the allocation of memory between various applications, plus the prioritization of applications in case multiple ones run simultaneously. Any program which is installed on a computer system functions by sending requests to the OS for different services using an application program interface (API). The interaction with the OS can be performed via a Graphical User Interface (GUI) or a command line. In the Internet hosting world, the OS is what commands a server along with all of the software installed on it, which includes not only website scripts, but, in addition every other application for instance a VOIP or a game server. When there're virtual machines created, they work with a guest OS which is run on the server host OS.
Multiple OS in VPS Servers
In case you choose one of our VPS server packages, you will have three different Operating Systems to select from - CentOS, Debian and Ubuntu. They're all Linux distributions and we offer them instead of offering just a single OS, because the applications that you might choose to run on the server could have specific requirements regarding the software environment. Each one of the three has some pros with regard to the available plans that you can later on install, but what is common between them is the fact that they're very stable and dependable and have huge communities which support them. The internet hosting Control Panel choices for the VPS accounts depend on your OS choice, so as to provide you with more flexibility. In case you order the virtual server with one OS and you need another one later, our tech support team can easily reinstall the VPS with the new one in a couple of minutes. We also offer you the option to maintain the Operating System on your server up-to-date on a weekly basis.
Multiple OS in Dedicated Servers
If you decide to buy one of our dedicated servers, you'll find three Operating Systems on the registration page because we want to give you a wider choice with regard to the system environment on your machine as different apps may have particular requirements. CentOS, Ubuntu and Debian feature different modules developed by their vast support communities, so you can select each of these OSs and enjoy a stable and secure web hosting service. Based on your selection, you'll also have different Control Panels to choose from. Needless to say, we can always replace the Operating System if the one you have selected at first doesn't meet the requirements of the software that you'd like to run. We can also update your OS routinely to keep it as secure as possible through our Managed Services upgrade package.
