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: Your Drivers and Utilities media may contain drivers for operating systems that are not on your computer. Ensure that you are installing
software appropriate for your operating system.
