Each and every virtual or dedicated hosting server has its own Os and operates independently from the hosting machines of other customers. Updating the Operating system is often neglected, but doing that may have a wide range of advantages for your internet sites. The most significant reason to employ the latest version is that patches are frequently released to fix security holes within the Operating System code, so if you don't install the updates, you risk individuals with destructive intentions to take advantage of these holes and to get access to your content. Operating system updates are also released for improved performance of the system as a whole and for far better compatibility with the hardware on the market, which can directly impact the functionality of your websites. If the performance and the security of your scripts is the reason to update them, you might also discover that their most recent versions require an updated Operating System in order to operate properly, thus keeping the OS up-to-date is always wise.
