Each virtual or dedicated hosting machine has its own Os and functions separately from the hosting servers of other customers. Updating the OS is frequently overlooked, but doing that may have quite a lot of benefits for your internet sites. The most essential reason to employ the newest version is that patches are usually released to deal with 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 much better performance of the system in general and for better compatibility with the hardware on the market, which can immediately influence the functionality of your websites. If the functionality and the security of your scripts is the reason to update them, you may also discover that their newest versions require an updated Operating System so as to operate effectively, therefore keeping the OS up-to-date is always recommended.
