Every virtual or dedicated hosting machine has its own Os and operates independently from the servers of other clients. Updating the Operating system is frequently neglected, but doing that may have a wide range of benefits for your websites. The most essential reason to employ the most up-to-date version is that patches are typically released to repair security holes in the Os code, so if you do not install the updates, you risk people with malicious intentions to use these holes and to access your content. OS updates are also released for enhanced performance of the system as a whole and for far better compatibility with the hardware on the market, which can instantly affect the performance of your internet sites. If the performance and the security of your scripts is the reason to update them, you might also know that their newest versions require an updated Operating System in order to work effectively, therefore keeping the OS up-to-date is always recommended.
