Chapter 6. Safety, use, and care information
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.
