Each and every virtual or dedicated server has its own Operating System and works independently from the hosting machines of other clients. Updating the OS is usually ignored, but doing that may have lots of benefits for your internet sites. The most essential reason to employ the newest version is that patches are typically released to repair security holes within the Os code, so if you do not install the updates, you risk individuals with malicious intentions to take advantage of these holes and to gain access to your content. Operating system updates are also released for enhanced functionality of the system as a whole and for far better compatibility with the hardware on the market, which can directly impact the efficiency of your internet sites. If the functionality and the security of your scripts is the reason to update them, you might also know that their latest versions require an updated Os to be able to function effectively, therefore keeping the OS up-to-date is always a wise idea.
