Chapter 6. Safety, Use, and Care Information
Device drivers are programs that contain instructions for the operating
system about how to operate or "drive" a certain piece of hardware. Each
hardware component on your computer has its own specific driver. If
you add a new component, the operating system needs to be instructed
on how to operate that piece of hardware. After you install the driver, the
operating system can recognize the hardware component and
understand how to use it.
Note:
Due to the fact that drivers are programs, like any other file on your
computer, they are susceptible to corruption and might not perform
properly if corruption occurs.
