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.
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.
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.
