A driver is a program that controls a device such as a printer, mouse, or keyboard. All devices require a driver program.

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® Windows® operating system.
