This is the weekly quiz for 2 October 2012 for the CSC 2060 course. Please do this quiz after you have completed the rest of assignment 1. It should take between one half hour and 2 1/2 hours to complete if you are well prepared, longer if not.

  1. Explain why some multiprocessor systems have a special read-modify-write bus cycle ... without releasing the bus.

  2. Explain what question having a bus arbitration mechanism answers.

  3. Explain the difference between a synchronous bus and an asynchronous bus and give an example of when an asynchronous bus is particuarly desirable.

  4. Explain what a bus driver is and why it is needed.

  5. List three types of pins on a CPU chip.

  6. Explain the difference between EPROM and EEPROM.

  7. Explain the difference between SRAM and DRAM.

  8. Summarize your proposed porfolio project.

  9. Summarize the three most important things you learned from Prof. Raman's 9th lecture.

  10. Summarize the three most important things you learned from Prof. Raman's 10th lecture.

  11. Following Tanenbaum, explain the difference between a latch and a flip-flop.

  12. Much of digital logic depends on doing one thing when a signal rises above some level and another thing when it drops below that level. Unfortunately, all electronic circuitry has to deal with noise, so that, instead of rising smoothly through any given level, a signal noisily goes up and down around that level multiple times. Do some research on the web and discuss how to design inputs to digital circuits so that they are not sensitive to noise. This is not in Tanenbaum.
