Module 3 Quiz >> Introduction to the Internet of Things and Embedded Systems

1.Under what conditions should an integrated circuit be used in an IoT device?

  • When highest performance is required.
  • When lowest power is required.
  • When the function is already commonly available as an integrated circuit.
  • All of the above.

2. Given a choice between implementing a function as an integrated circuit (in hardware) or as a program (in software), what factor needs to be considered the least?

  • The cost of manufacturing the integrated circuit.
  • The required time to design the integrated circuit vs. the program.
  • The performance required of the final product.
  • The physical look of the final device.

3. Generally, in a computer-based system, main memory is much larger than cache.

  • True
  • False

4. What is the fastest type of storage in a computer-based device?

  • Registers
  • Cache
  • Flash
  • Main memory

5. Which statement is false?

  • A programmer may write assembly code directly if performance is very important.
  • High-level languages are generally easier to program in than assembly language.
  • Machine language is universal, allowing programs written in machine language to be executed on any microprocessor.
  • Assembly code is easier to read than machine code.

6. What does an assembler generate?

  • Machine code from assembly code.
  • Assembly code from a high-level language.
  • Assembly code from machine code.
  • Machine code from a high-level language.

7. Compiled code generally executes faster than interpreted code.

  • True
  • False

8. Which of the following is NOT a benefit of using an operating system?

  • Many programs can execute on the same processor at the same time.
  • The frequency of the microcontroller clock can be significantly increased.
  • The operating system provides a convenient programming interface to the hardware.
  • The operating system enables separation between multiple processes.
