Questions and Answers

What component within the disk drive controls the HDA hardware?

  • Microcontroller
  • Firmware (correct)
  • I/O driver
  • Operating system

    • Does the presence of an I/O driver imply that the computer executing the driver is embedded?

  • Depends on the size of the computer
  • Yes, always
  • It is uncertain
  • No, never (correct)

    • Why are PDAs not considered embedded systems?

  • Because they have non-volatile memory
  • They are controlled by special hardware
  • They run office productivity applications (correct)
