Each and every virtual or dedicated server has its own Operating System and functions independently from the servers of other customers. Updating the OS is frequently ignored, but doing that might have lots of benefits for your sites. The most significant reason to employ the most recent version is that patches are frequently released to repair security holes within the Os code, so if you don't install the updates, you risk individuals with destructive intentions to take advantage of these holes and to access your content. Operating system updates are also released for improved efficiency of the system overall and for much better compatibility with the hardware available on the market, which could directly impact the functionality 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 latest versions require an updated Os in order to work properly, consequently keeping the OS up-to-date is always a wise idea.
