Lectures
The course instructor for CSCI 373.002 is J Dean Brock.
Lectures in CSCI 373.002 are from 3:10 PM to 4:25 PM on Tuesday and Thursday. The CSCI 373.002 lab will meet in RRO 217 on Tuesday afternoon from 4:35 PM to 5:50 PM.
When UNC Asheville is following the Late Start Schedule, the class will meet from 3:40 PM to 4:40 PM and the lab will meet from 4:50 PM to 5:50 PM.
Because class enrollment far exceeds the room capacity of RRO 217, the class will be divided into two separate lab “sections” which will attend the lab on alternate weeks.

Textbook and readings
The textbook for the course will be Computer Networks: A Systems Approach by Larry L. Peterson and Bruce S. Davie (ISBN-13: 978-0123850591). The UNC Asheville has an on-line copy of this book that you can read. We will go through this book in the “top-down pathway” described in the book’s preface: Chapters 1, 9, 7, 5, 3, 2 and 8. We will often use the textbook’s “Top-down Lecture Slides” in class discussions.
Additional readings of the course will be from on-line sources that will be referenced from the lecture schedule.
Software
We will use network monitoring applications built into Linux and Mac OS to “see” significant operating system structures.
We will also write networking applications using Python. Although you are not expected to have previous knowledge of Python, your previous programming experience should enable you to quickly learn a new programming language.
Python references
There are many free on-line resources for learning Python. Google for Education has a Python course that provides a good introduction. The Python Software Foundation also offers its own Python tutorials for both Python 2 and Python 3.
There are a large number of Python references that you can access on-line though the UNC Asheville library. Here are a few I that I have examined.
- Python: Visual QuickStart Guide by Toby Donaldson
- Python in 24 Hours, Sams Teach Yourself by Katie Cunningham
- Python for Kids: A Playful Introduction to Programming by Jason R. Briggs
- Introduction to Computation and Programming Using Python by John Guttag
- The Python Quick Syntax Reference by Gregory Walters
- Python Pocket Reference by Mark Lutz
- Twisted network programming essentials by Jessica McKellar and Abe Fettig
Python IDE’s
Many Python programmers use the IDLE IDE. (Ask a Monty Python fan to explain the name.) However, you may find it a bit primitive when compared to the NetBeans (or even the processing) IDE. We have the free versions of both PyCharm and Wingware installed in the lab. You may wish to install them on you personal systems.
Grades
The following weights are used in computing the course grade.
| Grade component | Weight |
|---|---|
| Two in-class ordinary exams | 1/4 |
| Two in-class practical exams | 1/8 |
| Final exam | 1/4 |
| Homework | 1/4 |
| Labs | 1/8 |
Exams
This course will have ordinary and practical exams. The distinction between the two is explained on the Exams and Practicals page.
All ordinary exams will be closed book and closed notes. No electronic devices, including calculators, may be used during the exam. If appropriate, reference sheets will be provided for details which
The practical exams will be completed using computers and will be scheduled during the course’s lab period.
Exam attendance
UNC Asheville’s Academic Policies and Procedures do provide excused absences for “travel on university-sanctioned business” and “up to two excused absences per semester for religious observances” when seven days notice is given. The instructor will announce exam times with at least ten days notice. This will allow the instructor to reschedule exams to avoid excused absences.
Homework
Students will complete near-weekly assignments to be turned in at class or submitted via the UNC Asheville moodle system.
Some homework assignments will require classroom presentations.
Students are required to cite any sources, including the work or advice of other students, used in completing their assignments. This rule implies that students must submit the names of any students with whom they have discussed a homework assignment. If this is not done, no credit will be given for the homework. Intensive use of other sources can result in adjustments to the homework grade.
Late homework
All homeworks have a specific due time. Late assignments will be accepted for up to four days with a penalty of 10% for each 24-hour period.
Labs
In general, the lab grade is passed on participation and graded on a 10-point scale.
- Students who complete all the objectives of the lab receive a grade of 9, the boundary grade between an A and B.
- Students who sparkle and inspire will receive 10, the A+++.
- Students who don’t read lab instructions will receive a grade not far from 7.
- Students who TXT constantly during the lab will be lucky to receive a 3.
Scale
The following numerical scale will be used in assigning grades based on Score, the score computed using the weights described above.
| Score ≥ 93 | A |
| Score ≥ 90 & Score < 93 | A- |
| Score ≥ 87 & Score < 90 | B+ |
| Score ≥ 83 & Score < 87 | B |
| Score ≥ 80 & Score < 83 | B- |
| Score ≥ 77 & Score < 80 | C+ |
| Score ≥ 73 & Score < 77 | C |
| Score ≥ 70 & Score < 73 | C- |
| Score ≥ 67 & Score < 70 | D+ |
| Score ≥ 60 & Score < 67 | D |
| Score < 60 | F |
Classroom expectations
The classroom is a place where students and faculty behave professionally. We are polite and attentive. We avoid talk of politics and religion. We do not use offensive language.
We all try to come to class on time. If students are late, they sit near the door. (A late instructor still must come to the front of the room.)
Electronics in the classroom
You are welcome to use your electronic devices to take notes. However, you should read the article Why students using laptops learn less in class even when they really are taking notes from the Washington Post before you give up on handwritten notes.
Electronic devices should not be used for gaming and social media during class. This distracts others in the class.
Sometimes you may need to discretely respond to a TXT message received during class. In these cases, it usually is best to leave the room. Do not use TXT messages to communicate to others in class. That is very impolite.
Required attendance
Some class activities, such as exams and labs, generate grades. You will receive a grade of 0 for the activities you miss. If you have an authorized excuse, you will be given an opportunity for a make-up.
Some class periods will be dedicated to student presentations. You are expected to attend all presentations by your fellow students. If you do not, your grade for own presentation will be adjusted.
Academic misconduct
It is never proper to claim another’s work as your own in graded work.
Impermissible actions
There are several impermissible actions that will result in the imposition of course or university sanctions. Impermissible actions in homework assignments include the following:
- Copying any portion of another student’s work by any method.
- Allowing another student to copy your work by any method.
- Incorporating program code, images, circuit diagrams, etc. into your homework solution that you did not create without citing the source.
Impermissible actions on exams include the following:
- Use of any unauthorized devices or sources of information.
- Giving and receiving information to another student by any method.
Sometimes these rules may be modified or clarified for specific assignments and exams. For example, ”pair“ programming may be allowed for an assignment, or simple scientific calculators may be allowed during an exam.
Course sanctions for impermissible actions
The first offense will result in a grade of 0 for the related assignment or exam. The second offense will result in a grade of F for the course.
University policy on academic misconduct
The UNC Asheville Student Handbook has a section devoted to Academic Misconduct. It states the following:
A student accused of academic dishonesty should talk with his or her instructor. In all situations where a student has been disciplined for plagiarism or cheating, the instructor is to submit to the VCAA a brief statement of the case; the student is to receive a copy of this document. Depending upon the severity and/or repetition of the offense, the VCAA may choose to impose a penalty of cancellation of graduation with honors; cancellation of scholarships; dismissal from the university; or any other penalty which he or she deems logical and deserved. A student has 10 class days to respond to this document, in writing; this response is to be sent to the VCAA for attachment to the document submitted by the instructor.
In practice, students who have been involved in academic misconduct in three courses will be suspended for a semester. However a single significant offense, such as the submission of a plagiarized paper, can result in immediate dismissal.
