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.
Dell ships your computer to you with required drivers already installed—no further installation or 
configuration is needed.
