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