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.
Many drivers, such as the keyboard driver, come with your Microsoft

operating
system. You may need to install drivers if you:
• Upgrade your operating system.
• Reinstall your operating system.
• Connect or install a new device.
