Each virtual or dedicated hosting server has its own Os and functions independently from the hosting machines of other clients. Updating the Operating system is frequently neglected, but doing that may have a wide range of advantages for your internet sites. The most important reason to use the most up-to-date version is that patches are usually released to deal with security holes inside the Operating System code, so if you do not install the updates, you risk people with harmful intentions to take advantage of these holes and to gain access to your content. OS updates are also released for much better functionality of the system as a whole and for much better compatibility with the hardware on the market, which can instantly impact the functionality 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 most recent versions require an updated Os so as to operate effectively, therefore keeping the Operating system up-to-date is always recommended.
