all are useful to see what kinds of topics are covered in this class.
Keep in mind, the rate of change for networks,
PCs and operating systems means the class will change quite a bit in response.
Here is a STUDY GUIDE for the
comprehensive final exam. It highlights the major topics and
Quiz one to four grade summary by
your secret code.
Monday, April 18th handout:
Homework due on Monday, April
25th. Much of it is from or refers to the textbook.
How does a Scanner work?
QUIZ ON MONDAY, APRIL 4th.
You got this outline/study guide as an email note.
Quiz THREE on Wednesday, March 9th - Includes new material on Hamming codeword, and the E F E R A basics.
Includes concepts of Framing and of Parity (Even and Odd Parity) for
error detection. Also, quiz three will cover
TIC (Tiny Imaginary Computer) fetch/execute cycle
and tracing of the instructions. You will be given the codes and do not have to memorize them, but you need to
have a good understanding of how the TIC instructions work together to get our data processed by fetching
instructions and data from memory and using a PC and an ACC to get the job done.
What is the difference between the sentinel approach
and the byte count approach to detecting the END of a Frame in the
Framing problem (the F of E F E R A)?
Attention: Quiz Two
note and outline/study guide, as well as tutorial on
ethernet and CSMA/CD protocol.
NICs and Transmission Media illustrations, etc.

Spring 2005 course reviews/previews
E F E R A - To be discussed during weeks 3 and 4
There are 5 issues to consider when connecting two nodes or computers with
some media like cable. They are EFERA.
Encoding, Framing, Errors,
Access are E, F, E, R, A.
Ethereal capture file exercise.
Tuesday, March 9th, 2004.
- Encoding the digital data on the signals that
the analog media can transmit, and decoding it back
to the digital binary pattern when received.
- Sentinel approach and byte count approach to know
the end of a frame. Detecting the exact start of
a frame is the other issue. "Not me" and "Mine"
- Error detection
- Even and odd parity. Hamming codewords.
CRC (Cyclic Redundancy Check)
- Reliable delivery
- Sliding windows. Timers and ACKs.
Automatic resend after timer goes off if no ACK from destination host.
- Access control
- CSMA/CD and CSMA/CA and token passing we
have already studied.
Parallel and Serial Ports.
Chips and Connections.
Cyclic Redundancy Check #1 and
Cyclic Redundancy Check #2 and
Practice interactive QUIZ (2 questions) for
redundancy bits. (32 bits attached to actual network packets, but 4 bits
Shell Programming followup from
the March 30th class.
Caeser cipher is a substitution
cipher. See the enciphering of UNI Panthers using every possible key
from 1 to 25.
Note: Tentative plan to have a quiz on April 8th.
