Each virtual or dedicated hosting server has its own Operating System and functions independently from the servers of other clients. Updating the OS is frequently ignored, but doing that may have a wide range of benefits for your internet sites. The most important reason to employ the latest 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 people with malicious intentions to take advantage of these holes and to get access to your content. OS updates are also released for enhanced performance of the system as a whole and for much better compatibility with the hardware available on the market, which could instantly influence the performance of your websites. If the functionality and the security of your scripts is the reason to update them, you could also discover that their latest versions require an updated Operating System so as to work effectively, thus keeping the OS up-to-date is always a good idea.
