An Operating System is the low-level software that manages a computer system. It handles the way your hardware functions, the communication with peripheral devices including a monitor, a printer or a keyboard, the allocation of memory between the installed applications, as well as the prioritization of applications if multiple ones run concurrently. Each and every program that's installed on a laptop or a desktop operates by sending requests to the OS for different services using an application program interface (API). The communication with the OS can be performed through a Graphical User Interface (GUI) or a command line. In the web hosting world, the Operating System is what runs a server and any software installed on it, which includes not only website scripts, but also any other application such as a VOIP or a game server. If there're virtual machines created, they use a guest OS that is run on the server host OS.
Multiple OS in VPS Servers
In case you choose to buy one of our VPS server
packages, you'll be able to select one of the three Linux releases which we supply for the Operating System of the servers - CentOS, Ubuntu and Debian. They're among the most widespread and most stable server OSs out there and we offer them in order to give you a choice for the software environment of your machine if you would like to install some app with specific requirements regarding the packages that must be present on the web server. We also offer three hosting Control Panels and which one of them you can use will depend on the OS that you have chosen. We leave the chance to change the server Operating System open, so if you want to use an application that requires an OS different from the one you have, we can always re-install the VPS. We can also keep the OS up-to-date on a weekly basis by installing any security updates that may be available.
Multiple OS in Dedicated Servers
We offer three Operating Systems with our dedicated server
plans - CentOS, Ubuntu and Debian. They're all different Linux distributions and we offer them not only because they are free so they won't increase the low price of your new web hosting server, but also because they are extremely stable and secure. Each one of them is supported by a vast community of web developers, so you'll be given the option to choose from thousands of software packages that you could install on your server if the app that you intend to work with has specific requirements. The Operating System will also determine what internet hosting Control Panel you can use as the Control Panels that we offer are compatible with specific OSs only and because we want to provide you with as much versatility as possible, we offer multiple OSs and multiple Control Panels. In case you choose a server with a given Operating System, we will change it upon request in the event that it turns out that you need another one. We can also keep your OS updated weekly as part of the optional Managed Services upgrade.
