PANIC BUTTON: Having problems with your lab?

While I'm usually at Canisius only on Wednesdays, you can reach me almost anytime via e-mail, at this address: buchegek@canisius.edu. NOTE: For the subject of your e-mail to me, put your name and the phrase "lab question."

During the semester I check my e-mail regularly, and this is your best way to get in contact with me regarding a question or problem with your lab.

Make sure to give me as much detail as possible about your problem. The more you can tell me about what's going wrong, the easier it will be for me to troubleshoot it with you and get you back on track.

      • #1.7: OMIT this question.
      • #1.8: Don't just guess -- you'll need to do research in your course textbook to properly answer this question. You're looking for information on fixed vs. dynamic partitions -- use the index of the book to find relevant information.
    • Exercise 2 -- Do the exercise with the following changes:
      • #2.2: The 2nd sentence is incorrect: the applet shown in the screenshots differs from the the one we're using.
      • #2.3/2.4: Instead of answering these questions, reproduce the chart below (draw it at the bottom of your Exercise 2 page) and fill it in, noting the Total Time and the Average Time for each of the 3 algorithms, as reported in the Messages & Statistics box of the applet. (READ THE IMPORTANT NOTE BELOW!)
      • Take one screenshot while running the applet, and hand it in.
  • Important Note: There is a bug in the Scheduling of Jobs applet, when running the Round Robin algorithm. The data created in the Messages & Statistics box after running the applet is incorrect. The correct data can be found here.
  • Fill in this chart for Exercise 2, #3-4:
