An Operating System is the low-level software that controls a computer system. It takes care of the way your hardware functions, the communication with peripherals for instance a monitor, a printer or a keyboard, the allocation of memory between the installed applications, along with the prioritization of apps when several run concurrently. Each program that is installed on a PC works by sending requests to the OS for various services by using an application program interface (API). The contact with the OS can be performed using a Graphical User Interface (GUI) or a command line. In the Internet hosting field, the OS is what runs a web server along with any software installed on it, which includes not only website scripts, but also any other application such as a VOIP or a game server. When there are virtual machines created, they work with a guest OS which is run on the server host OS.
Multiple OS in Dedicated Servers
In case you decide to get one of our dedicated servers, you shall find three Operating Systems on the registration page because we want to give you a wider choice regarding the system environment on the machine as different applications may have certain 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 reliable and secure web hosting service. Based on your decision, you'll also have different Control Panels to choose from. Needless to say, we can always change the Operating System if the one you have selected in the beginning does not meet the requirements of the software which you want to run. We can also upgrade your OS on a regular basis to keep it as risk-free as possible through our Managed Services upgrade package.
