Every virtual or dedicated server has its own Operating System and functions separately from the hosting servers of other customers. Updating the Operating system is usually neglected, but doing that may have lots of advantages for your internet sites. The most significant reason to employ the most recent version is that patches are frequently released to repair security holes within the Operating System code, so if you don't install the updates, you risk people with harmful intentions to exploit these holes and to gain access to your content. OS updates are also released for improved functionality of the system as a whole and for better compatibility with the hardware available on the market, which can instantly impact the performance of your websites. If the functionality and the security of your scripts is the reason to update them, you might also know that their newest versions require an updated Os so as to work properly, thus keeping the Operating system up-to-date is always recommended.
