An Operating System is the low-level software that controls a computer system. It takes care of the way the hardware behaves, the communication with peripherals such as a monitor, a printer or a keyboard, the allocation of memory between the installed applications, and the prioritization of applications when several run simultaneously. Any program that's installed on a desktop or a laptop operates by sending requests to the OS for various services by using an application program interface (API). The contact with the OS can be achieved via a Graphical User Interface (GUI) or a command line. In the hosting world, the OS is what runs a web server together with all the software installed on it, which includes not only website scripts, but, in addition any other application for instance a VOIP or a game server. When there are virtual machines created, they use a guest OS which runs on the server host OS.
Multiple OS in Dedicated Servers
The dedicated server plans that we offer come with as many as three different Operating Systems to choose from. They are all Linux release - Ubuntu, CentOS and Debian, and not only do they have no license fees, but they are also considered to be among the most reliable and risk-free OSs. We offer three different ones because each of them is supported by a different community. The packages which you can add on your server are different and this may matter in case you need to install some piece of software with particular requirements for the hosting environment. In this light, the web hosting Control Panel that you can select for the dedicated server also depends on the OS that you'll pick. You can pick any of the three Operating Systems throughout the order procedure, but if needed, we can always set up the server anew with another one upon your request. As an optional service that you may add to the plan at any moment, we can update the OS regularly to keep it as secure as possible.
