Different computer drives
A driver is software that allows your computer to communicate with hardware or devices. Without DRIVERS, the hardware you connect to your computer—for example, a video card or a webcam—will not work properly.
In computing, a device driver (commonly referred to as a driver) is a computer program that operates or controls a particular type of device that is attached to a computer. A driver provides a software interface to hardware devices, enabling operating systems and other computer programs to access hardware functions without needing to know precise details of the hardware being used.
