Every virtual or dedicated hosting server has its own Operating System and operates independently from the servers of other customers. Updating the Operating system is often ignored, but doing that might have quite a lot of benefits for your websites. The most important reason to use the latest version is that patches are frequently released to repair security holes within the Operating System code, so if you do not install the updates, you risk individuals with malicious intentions to exploit these holes and to access your content. Operating system updates are also released for much better functionality of the system as a whole and for better compatibility with the hardware on the market, which can immediately impact the performance of your internet sites. If the performance and the security of your scripts is the reason to update them, you could also find out that their newest versions require an updated Os so as to work properly, consequently keeping the Operating system up-to-date is always wise.
