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 often overlooked, but doing that might have lots of advantages for your internet sites. 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 harmful intentions to use these holes and to gain access to your content. OS updates are also released for enhanced performance of the system overall and for far better compatibility with the hardware on the market, which can directly impact the efficiency of your internet sites. If the performance and the security of your scripts is the reason to update them, you might also find out that their latest versions require an updated Operating System in order to operate properly, thus keeping the Operating system up-to-date is always a good idea.
