If you get a hosting server of your own, it will run independently, so it will have its own Os and you'll be able to later install server side programs directly or script-driven sites through a hosting Cp. Even though keeping the Operating System updated is not always considered fundamental, it can be a quite important task for a number of reasons. A more modern Operating system version could have better support for specific hardware, so you might get better performance for the internet sites and web applications which you install. Your server shall also be more safe since updates usually include security patches which deal with small problems which may permit unauthorized individuals to access your content. Last, but not least, more recent script versions, which are also released for both enhanced security and for additional features, might require a later version of the Operating System in order to work correctly and with their full capabilities.
