An Operating System is the fundamental software that controls a computer system. It handles how your hardware functions, the communication with peripherals like a monitor, a printer or a keyboard, the allocation of memory between applications, and the prioritization of applications when multiple ones run concurrently. Each program that's installed on a desktop or a notebook functions by sending requests to the OS for different services by using an application program interface (API). The interaction with the OS can be done through a Graphical User Interface (GUI) or a command line. In the web hosting field, the Operating System is what commands a web server and any software installed on it, which includes not only website scripts, but, in addition any other application such as a VOIP or a game server. In case there're virtual machines created, they employ a guest OS that runs on the server host OS.
Multiple OS in VPS Servers
If you decide to buy one of our VPS server packages, you shall be able to opt for one of the three Linux releases that we provide for the OS of the servers - CentOS, Ubuntu and Debian. They're among the most well-known and most reliable server OSs available and we offer them so that you have a choice for the software environment of your machine in case that you want to install some application with precise requirements with regards to the packages that must be present on the web server. We also offer three internet hosting Control Panels and which one of them you may use depends on the OS that you've chosen. We leave the chance to replace the server Operating System open, so if you want to use an application that requires an OS different from the one you already have, we can always re-install the VPS. In addition, we can keep the OS up-to-date weekly by installing all of the security updates which may be available.
Multiple OS in Dedicated Servers
In case you decide to purchase one of our dedicated servers, you shall find three Operating Systems on the order page as we want to give you a wider choice with regard to the system environment on the server as different apps could have particular requirements. CentOS, Ubuntu and Debian include different modules developed by their huge support communities, so you can select each of these OSs and enjoy a stable and risk-free Internet hosting service. Depending on your choice, you will also have different Control Panels to choose from. Of course, we can always replace the Operating System if the one you have selected initially does not meet the requirements of the software that you want to run. We can also upgrade your OS on a regular basis to keep it as secure as possible through our Managed Services upgrade package.
