Agenda 13
for class on
Monday April 16
- Handouts
- Agenda
- Making a Personal Web Page
- Final Topics - review this week and bring next week for Q&A
- Computers and Society
- Passbacks
- Assignments and Labs (as ready).
- Announcements:
- Before you leave tonight, fill in the online Attendance (Signin) form on the course web
site.
- 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.
- 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.
- The SET (Student Evaluation of Teaching) will be in class today.
- 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.
- Today the Agenda includes the list of topics for the Final Exam. This will also be
available on the course web site. We will spend one hour in class next week, on April 23
going over the topics. As always, in addition to the in-class review, you can call, come
to the office hours, email, or contact me in any other way for help or clarification.
Also, the Lab that night will be some computer programming, on the Lab computers. If you
want to see if you can do this work at home, find the files "QBasic.exe" and
"QBasic.bas", copy them onto a floppy diskette, and copy them onto your hard
drive at home. Start the system by double-clicking on the exe file.
- 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.)
- 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.
- If you want to try next 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.
- 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.
- 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.
- Summary of items of interest in this class on David Bowen's web site:
- Page on having a good college experience
- Request a grade of I or other non-standard grade
- Use web graphics gallery
- Use file uploader for web pages
- Instructor's schedule
- Internet "Applications" are programs that use this transmission mechanism
- 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.
- Client-server is much more common
- A client requests information from a server, displays information when it is received
- 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
- Clients and servers using the same application protocol are (supposed to be)
interchangeable.
- E.g., email has three primary protocols
- POP (currently POP3) or Post Office Protocol
- IMAP (currently IMAP4) or Internet Mail Access Protocol
- 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.
- Client and server must be matched at each end, but can be different at the two ends
- Email. Client A is first user, with an account on mail server #1, a second client, B,
has an account on mail server #2. A addresses a message to B, sends it by transmitting it
to mail server #1, mail server #1 sends it to mail server #2. Message waits until B logs
on, picks up message. Uses simple text for messages, but can attach files to messages.
There are two major protocols -- POP (Post Office Protocol) and IMAP (Internet Message
Access Protocol). POP is simpler and more popular, IMAP more comprehensive and is commonly
supposed to be the future. Client and server must use the same protocol, POP or IMAP. Some
email server computers run both servers, and some email clients can be configured either
way.
- Internet email address has two parts separated by @. e.g. d.r.bowen@wayne.edu
- part to left of @ is name of account (d.r.bowen)
- part to right of @ is email server that account is on (wayne.edu)
- Convergence
- Definition - many hardware / software options merging into one
- Examples
- cell phones that do email and are web browsers
- DSL doing telephone and Internet access in one line; VDSL adding cable to the mix
- Merging of broadcast Radio and TV into one Internet service
- Social issues
- Get your kids into this stuff to give them more options
- Go to handout
- Paper and Pencil Computer - go to handout
Lab 13.
Use the web page handout to make a personal web page and upload it to the web server.
We will review this briefly in class. Your personal home page should have:
- Text in at least two formats
- A link, at least a link back to the welcome page for the class web pages (set "Link
to a page location or local file:" to "welcome.htm")
- A graphic, for example your picture in the class photo gallery or one from the web
graphics gallery
For uploading, use the web uploading page described in the handout. Here is the account
information you will need:
- User Name: casw01
- Password: stustu
Assignment 13. Please write or type
"Assignment 13" on the work you turn in for this assignment (due 4/23).
- In Computers, Technology, and Society, read Chapter INT and answer the following
Review questions on pg INT-35: 2, 4, 5 and 8. (NOTE: Also look over the AI questions on
the Final Topics, before you read this Chapter.)
