CIS 525: Telecommunications and Data Communications Systems


  • December 12th: ATTENTION: (FINAL EXAM TIME) I goofed and told you all a wrong time for the final exam. The final exam is from 11:50 AM – 1:40 PM. I'll be there at 10:50 anyway, but the final is not 3 hours long. :) Again, we start at 11:50 AM in Nichols 236 (our usual room). Thanks all, -Eugene
  • December 7th: Hi all, there's an I will have office hours on Monday and Wednesday, 10:30 to 12/noon. None on Friday, since they interfere with our final, and thus are not very useful. Thanks!
  • December 3rd: Hi all, there's an unfortunate error in the slides in the example of how to compute the Hamming Codeword. The expansion is wrong. The data for which we're computing the codeword should be "1001011" and the codeword is "10110010011". Slides have been updated on KSOL and we'll revisit the example on Wednesday.
  • November 29th: Homework 5, the last one of the semester, has been posted on KSOL. It's due on Friday December 7th by class time. Thanks all, see you in class tomorrow.
  • November 27th: If snmpget or the example SNMP client are not working for you, try snmpget -v1 -c public . rather than what is given in the example. This is the OID – object identifier. To make the example code work, grab the file ipInReceives.txt which I just added to the snmpnet directory, and take a look at the README. ./myClient < ipInReceives.txt should now work as advertised.
  • November 26th: Thanks to quick action by out IT folks (thanks!!), SNMP is up and running again. The output of snmpget looks slightly different than the example, but that shouldn't be an issue – the required information is still there.
  • November 25th: We seem to have a temporary problem with snmpget. Hopefully it will soon be functional again. Remember, no class until Friday December 30th. See you then.
  • November 16th: I'll be out of town the first half of the week after break, so we won't have class on Monday November 26th or Wednesday November 28th. We'll reconvene on Friday, November 30th. Thanks, and enjoy your break!
  • November 5th: Programming assignment 3 is (finally) up on KSOL. It's due on Friday, November 30th, by 9:30 AM. This will be the last programming assignment this semester.
  • October 31st: Homework 4 has been posted, and is due Friday November 16, by 9:30 AM (class start time) through KSOL. Remember, if it's going to be late, it's best to submit what you have and them email me the finished version. Same goes for programming assignments. You will still lose points for being late, but not as many as if you turn in nothing on time.
  • October 25th: The second (and last) long-form quiz on Wednesday, November 7th. You'll have the entire class time to do it. The quiz covers everything between the start of class and the lecture right before the quiz. We will have a review on Monday the 5th. In the meantime, please come see me or Hong at office hours (or make an appointment) if some material is unclear. Thanks.
  • October 14th: Homework 3 has been posted on K-State Online, in the Assignments folder. It's due electronically – upload to K-State Online by Friday, October 19, 2012, before 9:30 AM (class start time).
  • October 7th: Programming Assignment 2 has been posted on KSOL; it's due on Friday, October 26, by 9:30 AM.
  • September 24th: Quiz 1 will be given in class on Wednesday, October 3rd. There will be no class on Monday October 1st or Friday, October 5th. However, programming assignment 1 is due online before 9:30AM on October 5th, even though there's no class.
    To summarize:
    • Programming assignment 1: Due September 28th by 9:30AM
    • Homework 2: Due October 5th by 9:30AM
    • Quiz 1 on October 3rd in class

  • September 24th: Homework 2 has been posted on K-State Online, in the Assignments folder. It's due electronically – upload to K-State Online by Friday, October 5, 2012, before 9:30 AM (class start time).
  • September 11th: Programming Assignment 1 has gotten another minor correction. Sorry about that.
  • September 10th: The corrected version of Programming Assignment 1 has been uploaded. Sorry for any confusion. Remember to run the server (in the background using the "&" operator in the shell) before you run the client.
  • September 7th: Mostly to help me get a feel for your progress and understanding (and adjust my lecture presentation style), I'll be giving very short in-class quizzes in the future. These will be worth only a few points (contributing to 5% of your overall grade), will take no longer than 10 minutes, and will include two or three multiple-choice questions or one or two fill-in-the-blank questions. These quizzes will not be announced in advance. Thanks for coming to class!
  • September 3rd: Programming Assignment 1 has been posted on K-State Online, in the Assignments folder. It's due electronically – upload to K-State Online – by Friday, September 28, 2012, 9:30 AM (class start time). Start work on this early to avoid potential problems. Please come see Hong or myself with any questions.
  • August 29th: Notice the new External resources link on the left side.
  • August 27st: Homework 1 has been posted on K-State Online, in the Assignments folder. It's due electronically – upload to K-State Online – by Friday, September 7, 2012, by 9:30 AM (class start time). Please come see Hong or myself with any questions. You can also find helpful worksheets on K-State Online – they are not assignments, but I would strongly suggest you work through those examples.
  • August 27st: Remember to SSH to the on-campus computers – see http://support.cis.ksu.edu/UserGuide/Facilities for instructions. Look at "man" pages for system calls and commands you want to learn. Use "man -a" to get all "versions" of the command, such as the C programming version and the shell "built-in" version. Remember to look up the commands on the department Linux machines, since these are the ones we will use to grade.
  • August 21st: My office hours this semester will be Wednesdays and Fridays 10:30AM – 12:00PM (right after class). The schedule and syllabus have been changed to reflect this.
  • August 20th: I hope you all enjoyed your first day of class! The "evaluation" section is now back in the syllabus – sorry for that omission. My office hours are still TBA, coming soon! If you need to see me in the meantime, please catch me after class or email me.
  • August 17th: Hi all, just wanted to remind you that first day of class is Monday. There's a waiting list, so please attend! Also, I know paper has gone out of style, but just this once, please print out and bring a copy of the syllabus with you to Monday's class. Thanks!
  • August 15th: Welcome! Please see the syllabus page for a class overview and a few other goodies. We will use mainly this page for announcements, schedule changes, etc. (so check this page often!), but for assignments and grades, look in your Organizer in K-State Online.
  • August 14th: Web page posted.
