Each and every virtual or dedicated hosting server has its own Operating System and operates separately from the servers of other clients. Updating the Operating system is often overlooked, but doing that may have lots of benefits for your websites. The most significant reason to employ the latest version is that patches are frequently released to fix security holes in the Operating System code, so if you don't install the updates, you risk individuals with malicious intentions to take advantage of these holes and to gain access to your content. Operating system updates are also released for enhanced performance of the system in general and for better compatibility with the hardware on the market, which could immediately impact the performance of your websites. If the performance and the security of your scripts is the reason to update them, you may also know that their latest versions require an updated Operating System to be able to operate effectively, so keeping the Operating system up-to-date is always wise.
