Each and every virtual or dedicated server has its own Operating System and works separately from the hosting machines of other clients. Updating the Operating system is frequently overlooked, but doing that might have a wide range of advantages for your internet sites. The most important reason to use the most recent version is that patches are frequently released to fix security holes within the Os code, so if you don't install the updates, you risk individuals with malicious intentions to take advantage of these holes and to access 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 available on the market, which could instantly influence 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 so as to work properly, so keeping the Operating system up-to-date is always a good idea.
