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 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.
•You reinstall your operating system.
•You connect or install a new device.
