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 installedno further installation or configuration is needed.
Many drivers, such as the keyboard driver, come with your Microsoft Windows operating system. You may need to install drivers if you:
lUpgrade your operating system.
lReinstall your operating system.
lConnect or install a new device.
