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 the programs that use the device. Each device
has its own set of specialized commands that only its driver recognizes.
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.
If you experience a problem with any device, perform the steps in the following sections to identify
whether the driver is the source of your problem and if necessary, to update the driver.
