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 optional 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.
Many drivers, such as the keyboard driver, come with your Microsoft Windows operating system. You may need to install
drivers if you:
Upgrade your operating system.
Reinstall your operating system.
Connect or install a new device.
Identifying Drivers
If you experience a problem with any device, identify whether the driver is the source of your problem and, if necessary,
update the driver.
