A driver is an absolutely essential piece of software which helps your computer to communicate with hardware and devices. If a computer is missing key drivers, then hardware such as printers, keyboards, and even video cards may cease to work entirely. While first generation drivers may sometimes be unrefined and riddled with troublesome bugs, device manufacturers often release driver updates. These essential updates can improve device functionality, as well as removing any lingering errors. Thus, the more recent the driver, the better your device will run and your computer perform.
