Each virtual or dedicated server has its own Operating System and works separately from the hosting servers of other customers. Updating the Operating system is usually overlooked, but doing that may have lots of benefits for your sites. The most essential reason to employ the most recent version is that patches are usually released to fix security holes inside the Operating System code, so if you do not install the updates, you risk individuals with harmful intentions to take advantage of these holes and to access your content. OS updates are also released for improved performance of the system overall and for better compatibility with the hardware on the market, which could instantly affect the efficiency of your websites. If the efficiency and the security of your scripts is the reason to update them, you might also know that their most up-to-date versions require an updated Os to be able to operate properly, thus keeping the Operating system up-to-date is always a wise idea.
