Each and every virtual or dedicated hosting server has its own Operating System and works separately from the servers of other clients. Updating the Operating system is often overlooked, but doing that may have lots of advantages for your internet sites. The most significant reason to employ the latest version is that patches are usually released to deal with security holes in the Operating System code, so if you do not install the updates, you risk individuals with destructive intentions to exploit these holes and to gain access to your content. Operating system updates are also released for enhanced efficiency of the system in general and for far better compatibility with the hardware available on the market, which can immediately influence the efficiency of your sites. If the functionality and the security of your scripts is the reason to update them, you may also discover that their most up-to-date versions require an updated Operating System to be able to function effectively, therefore keeping the OS up-to-date is always recommended.
