Agenda 14
for class on
Monday April 23

1. Handouts
   1. Agenda
   2. QBASIC
2. Passbacks
   1. Assignments and Labs (as ready).
3. Announcements:
   1. Before you leave tonight, fill in the online Attendance (Signin) form on the course web site.
   2. If you miss a class, before the next class you should go to the course web site (the URL is in the upper left-hand corner of every handout) and review the Agenda for that class, then contact me if you have questions. Assignments and quiz topics are listed on the Agenda.
   3. If you need to make up a Quiz, or ask questions, or whatever, my office hours are time set aside for this. These times are Mondays and Wednesdays, 4 - 6 PM, in 113 Rackham (the classroom).
      
      If these times do not work for you, contact me to make other arrangements.
      
      I will not let you start a Quiz if the full half hour is not available before the start of the Monday night (I teach that one, of course) or Wednesday night (someone else teaches that one) class - both start a 6 PM, so 5:30 PM is as late as you can start a Quiz.
   4. The SET (Student Evaluation of Teaching) will be in class today.
   5. The Final Exam will be Monday, April 30, during the normal class day, time and location (113 Rackham). The Final will be cumulative. The topics for the previous exams will be part of the topics for the Final. There will be no other class activity that night. April 30 is also the deadline for all work that will count in the regular grade. Late work will result in a later Change of Grade.
   6. Many of you turn your work in with all of your work stapled together into one packet. Please do not do this, but turn in a stapled packet for each assignment (or lab or test, etc.) separately. I grade each assignment for all students at the same time. (This gives me more assurance of treating everyone equally.)
   7. Reminder - Lab 10 assigns posting two messages on the course computer conference, one a response to the topic "What I would like help on," and the second can be a new topic, or a reply to any other posting.
   8. If you want to try this week's lab at home (QBASIC), the handout is on the course web site, under Agenda 13 (this week's Agenda). If you are thinking of trying this at home, I would install QBASIC and give this a try to make sure that you will able to do it at home. To install QBASIC at home, find the files "QBasic.exe" and "QBasic.hlp" on your desktop in the lab tonight, copy the files onto a floppy diskette, and copy them onto your hard drive at home.
   9. The semester is fast coming to an end. If you are behind in the assignments, you may want to consider an Incomplete (I), a grade that lets you take extra time to finish the course work. There is a web page on I and similar grades on my web site at http://www.cll.wayne.edu/isp/drbowen, which you can use to request an I.
   10. Also there is a web page there on having a good college experience, based on a long-term study at Harvard University. "Good" includes both grades and satisfaction.
   11. Summary of items of interest in this class on David Bowen's web site:
       1. Page on having a good college experience
       2. Request a grade of I or other non-standard grade
       3. Use web graphics gallery
       4. Use file uploader for web pages
       5. Instructor's schedule
4. Internet "Applications" are programs that use this transmission mechanism
   1. Peer applications have two computers acting as equals, but this is fairly rare. That is, until Napster and others. With Napster, the basic listing of songs and where to find them is on a central server, but the actual files are transported client-to-client. With Gnutella, everything is client-to-client. Very difficult to sue.
   2. Client-server is much more common
      1. A client requests information from a server, displays information when it is received
      2. Server sits and waits for information request, services request when request is received. Server seems to be simpler, but it must be able to service simultaneous requests, also expected to be very robust -- always available
      3. Clients and servers using the same application protocol are (supposed to be) interchangeable.
         1. E.g., email has three primary protocols
            1. POP (currently POP3) or Post Office Protocol
            2. IMAP (currently IMAP4) or Internet Mail Access Protocol
            3. Web-based email such as hotmail. Becoming very popular since it requires much less configuration than others, web-knowledgeable users already know how to use it.
            4. Client and server must be matched at each end, but can be different at the two ends
5. Addition to topics for Final. After hearing questions and comments about this, many are confused by the difference between viewing a web page with a web browser and editing or changing a web page with an editor. So:
   1. Give examples of web browsers and web page editors.
   2. Describe the difference between using a web browser and a web page editor.
6. Paper and Pencil Computer - go to handout

Lab 14.

Carry out the lab on the QBASIC handout. Turn in the program listings and other information described in the lab.

Assignment 14.  There is Assignment 14.
