Drivers
What Is a Driver?
A driver is a program that controls a device such as a printer, mouse, or
keyboard. All devices require a driver program.
A driver acts like a translator between the device and any other programs that
use the device. Each device has its own set of specialized commands that only
its driver recognizes.
