-------- Original Message -------- Subject: COMPSCI.314SC ANNOUNCEMENT: General information about the final exam Date: Fri, 15 Oct 2010 10:04:21 +1300 From: Brian Carpenter Organization: University of Auckland To: Brian Carpenter The lectures for COMPSCI 314 are now over. The slides, and recordings of most of the lectures, may be found via http://www.cs.auckland.ac.nz/courses/compsci314s2c/lectures/ The final exam for COMPSCI 314 will be held on Thursday 28 October 2010 from 2:15 to 4:30 p.m. The exam rooms will be announced via http://www.auckland.ac.nz/uoa/cs-examination-information We have been asked to remind you that official examination timetables are only available from Student Services Online, as paper versions of examination timetables are no longer being mailed out. The scope of the exam is the whole course, with about 20% covering the material taught by Clark Thomborson, and about 40% each for the material taught by Brian Carpenter and Nevil Brownlee. There will be 11 short answer questions, adding up to exactly 100 marks. You will have two hours, so a safe guideline is one mark per minute (10 minutes to answer a 10 mark question, etc.). No calculators. Good luck! -- Regards Brian Carpenter Department of Computer Science The University of Auckland http://www.cs.auckland.ac.nz/~brian/ -------- Original Message -------- Subject: COMPSCI.314SC ANNOUNCEMENT: Lecture 15 Oct (last 314 lecture) Date: 15 Oct 2010 12:26:42 +1300 From: n.brownlee@auckland.ac.nz Hi all: Sorry, my previous announcement about this had URLs that didn't point to anything.

"What is the size of an ACK frame?" As always in an assignment or an exam question, if you have to make an assumption, write down what your assumption is. In this case, a reasonable assumption is 64 bytes (as used in the lectures). Since that is the minimum size of an Ethernet frame, it is very likely to be the smallest frame you will see in real life. 2. "I'm using the formula on page 359 of the text book. What's the value of F?" Firstly, the book uses bits, but it's more common to talk about bytes when discussing the size of a frame. That's just a matter of multiplying or dividing by 8. Secondly, the book seems to assume that the data packets include an ACK (so that F = N + A). But we don't need an ACK with the data; the ACK frames are coming back the other way. For the example in the lectures, and the assignment, we just have F = N. (As mentioned briefly in the lectures, some designs use "piggy back ACK", with both data and ACKs in both directions. The textbook seems to be assuming that without mentioning it.) 3. "I get a strange result for part of Q2a." Whenever you get a strange result, think about it and try to explain it! 4. "I don't have enough information for Q3." Look at slide 20 from the first lecture of the semester. Then it should only take a few seconds to repeat the calculations for each part of Q1 and Q2. (This wasn't intended as a trick question - I knew it was mentioned, although I forgot that it was at the very beginning. Or you could work it out from the fact that geostationary satellites are 35,786 km above the surface of the Earth, but we don't need to be that precise.)

One student forgot to write their name on their script. If you were that person (i.e. if you sat the test but no marks were reported), please visit Habib to pick up your script. (Please be sure to show Habib your student-ID card -- I doubt that multiple people would attempt to claim this script, and I can't expect Habib to do a handwriting-analysis and face-recognition authentication of your claimed identity at 100% accuracy, but... even so, I'll ask him to sight your student ID card, just in case we do have multiple claimants ;-) Cheers, Clark -------- Original Message -------- Subject: COMPSCI.314SC ANNOUNCEMENT: test scores available on Cecil Date: 14 Sep 2010 16:14:28 +1200 From: c.thomborson@auckland.ac.nz Dear COMPSCI 314 students, Your test scores are now available on Cecil. Sample answers are posted at http://www.cs.auckland.ac.nz/courses/compsci314s2c/exams/. The class average was 30/50. You'll find a few other summary statistics on the test marks on the last page of the sample-answer file. I'll soon give your scripts to your tutor, Habib. After he receives them, he'll send you a message, explaining when and where you can retrieve your script from him. (We can't just put them in the hallway -- because someone might "steal" yours.) I hope you take the time & trouble to retrieve your script from Habib, for two reasons: 1) I make an occasional mistake when adding up numbers, and so there's a non-zero chance that one or two students in this class will find a "bug" in my addition; 2) I wrote some (probably barely legible ;-) comments on test scripts while marking, and you may find these comments useful (but only if you read them ;-). If you do find an addition mistake in my marking, please see me during office hours (Tuesday 2-3pm and Thursday 2-3pm, in room 303S.593).

I had muted the podium mike, thinking that the pickup from the radio mike would be clearer if it weren't being level-adjusted, automagically, every time my voice was picked up (or not) by the podium mike. The lecture-recording folks are diagnosing the radio-mike setup in E1.401. A video-only recording is available at http://mediastore.auckland.ac.nz/2010/08/AD252A2062F94135A859F03D67B52EB8/A201008060900.LTRD253558.preview ... but I wouldn't suggest watching that.

The audio stream in yesterday's lecture recording was inaudible, because I didn't manage to turn on the lapel mike. The audio stream in today's recording is barely audible -- I suspect that the audio mixer was set to take the podium mike signal, rather than the lapel mike signal. Maybe next time I'll get it right! I'd suggest you play the low-res video at full audio volume, and that you display http://www.cs.auckland.ac.nz/courses/compsci314s2c/lectures/TransmissionCoding.pdf so that you can read the slides clearly. (Most video codecs aren't very good at handling powerpoint, and the one used here for lecture-recording is no exception -- we'll talk about video compression briefly next week.)
