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.
