Every virtual or dedicated hosting machine has its own Operating System and operates independently from the servers of other customers. Updating the Operating system is frequently neglected, but doing that could have a wide range of benefits for your internet sites. The most significant reason to employ the newest version is that patches are frequently released to deal with security holes inside the Operating System code, so if you do not install the updates, you risk people with malicious intentions to exploit these holes and to access your content. Operating system updates are also released for improved efficiency of the system in general and for far better compatibility with the hardware available on the market, which can directly impact the functionality of your websites. If the efficiency and the security of your scripts is the reason to update them, you may also discover that their newest versions require an updated Os to be able to function properly, consequently keeping the OS up-to-date is always recommended.
