Each and every virtual or dedicated hosting server has its own Os and functions separately from the hosting servers of other clients. Updating the Operating system is often ignored, but doing that may have a wide range of benefits for your internet sites. The most important reason to use the latest version is that patches are frequently released to fix security holes inside the Os code, so if you do not install the updates, you risk people with malicious intentions to take advantage of these holes and to access your content. Operating system updates are also released for enhanced functionality of the system as a whole and for far better compatibility with the hardware on the market, which can instantly impact the efficiency of your sites. If the performance and the security of your scripts is the reason to update them, you might also find out that their newest versions require an updated Operating System so as to work effectively, consequently keeping the Operating system up-to-date is always wise.
