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.
NOTICE:
The Drivers and Utilities CD may contain drivers for operating systems that are not on your computer.
Ensure that you are installing software appropriate for your operating system.
