If you get a server of your own, it will work independently, so it will have its own Operating System and you can later install server side apps directly or script-driven internet sites through a hosting Control Panel. Though keeping the Operating System updated is not always considered a necessity, it can be a rather important task for a number of reasons. A newer OS version might have better support for certain hardware, so you may get better performance for the sites and web applications that you install. Your server will also be more secure as updates usually include security patches that deal with small problems which may allow 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 effectively and with their 100 % capabilities.
