Each and every virtual or dedicated server has its own Os and functions independently from the hosting servers of other customers. Updating the OS is often overlooked, but doing that may have lots of advantages for your websites. The most essential reason to use the most up-to-date version is that patches are frequently released to repair security holes in the Operating System code, so if you do not install the updates, you risk individuals with malicious intentions to take advantage of these holes and to gain access to your content. Operating system updates are also released for improved functionality of the system overall and for much better compatibility with the hardware on the market, which can instantly influence the functionality of your websites. If the efficiency and the security of your scripts is the reason to update them, you could also discover that their most up-to-date versions require an updated Os so as to work effectively, thus keeping the OS up-to-date is always a wise idea.
