Every virtual or dedicated hosting server has its own Operating System and operates independently from the hosting machines of other clients. Updating the OS is frequently ignored, but doing that might have lots of benefits for your websites. The most significant reason to use the most recent 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 harmful intentions to take advantage of these holes and to gain access to your content. OS updates are also released for improved performance of the system as a whole and for better compatibility with the hardware on the market, which could immediately impact the functionality of your internet sites. If the efficiency and the security of your scripts is the reason to update them, you may also discover that their most up-to-date versions require an updated Operating System so as to operate effectively, consequently keeping the Operating system up-to-date is always wise.
