CoreTextbook:
1. Computer Networking: A Top-Down Approach by James F. Kurose
and Keith W. Ross. In particular, the sixth international edition (which
is written in English) . As an alternative you may use 5th edition from
Khazar Library.
2. Data Communications and Computer Networks: A Business User’s
Approach, Seventh Edition Curt M. White,2014;
3. Andrew S. Tanenbaum, Computer Networks, 5-th Edition,. Prentice
Hall, 2011;
Course outline
If you take this course, you will learn all about network architectures and the
principles on which they rely. By the end of the semester, you will know how
TCP/IP works, what Internet routers look like inside, why your Internet
connection is sometimes very slow, and what are the main threats to Internet
security. You will also be able to design and code very simple network
applications and protocols and perform simple network troubleshooting.
Course objectives
The course is targeted at undergraduate students who have not studied
computer networks before. It consists of lectures and lab sessions. During the
latter, we will work together through simple hands-on exercises to gain
experience with network protocols and practical tools.
By the end of the Course students should be able:

 Preparation for class
Come to the lecture every Wednesday and Friday .
After listening to the lecture, read the relevant textbook chapters (indicated here).
Before going to an exercise session, take a look at the exercises.
You can use the homework-correction sessions in one of two ways:
Work on the homework before going to the session and use the session to ask
clarifying questions to your teaching team.
Work on the homework during the session, asking for help as needed.
We think that the first way will help you better to prepare for the exams.
 Hands-on exercises & homework assignments
We will work together through several hands-on exercises, so that you experiment
with network protocols and practical tools.
We will also work together through several homework assignments, so that you
train for the exams (described below).
The hands-on exercises and homework assignments will not be graded.
 Midterm and final exams
There will be a midterm and a final written exam.
Both exams will contain questions and problems on material that: was taught in
the lectures, learned through the homework assignments, and/or learned through
the hands-on exercises.
Both exams will be closed-book, but you will be welcome to bring an "aidemémoire" (see definition below). During the exam, each student should use only
his or her own aide-mémoire.
The "aide-mémoire" is a document of at most two A4 sheets (four one-side A4
pages) for the midterm and four A4 sheets (eight one-side A4 pages) for the final
exam. It can be hand- or typewritten. It can be a photocopy. It can contain colors
and drawings. The font can be as small as you wish, but you should be able to
read it without auxiliary tools (e.g., a magnifying glass).
 Quizzes
Sometimes, at the beginning of the lecture, there will be a closed-book written
quiz that will last 10 minutes or so.
Each quiz will consist of a number of simple questions, related to material
covered in previous lectures.
Quizzes will be graded, but the grades will count toward your final grade only if
you do well (see grade computation below).
For reasons of fairness, we cannot give replacement quizzes (for students that are
absent during a quiz). But keep in mind that quizzes can only improve your final
grade, never decrease it. So, missing a quiz may not affect your final grade at all.
 Cheating/plagiarism
Cheating or other plagiarism during the Quizzes, Mid-term and Final
Examinations will lead to paper cancellation. In this case, the student will
automatically get zero (0), without any considerations.

Professional behavior guidelines
The students shall behave in the way to create favorable academic and
professional environment during the class hours. Unauthorized discussions and
unethical behavior are strictly prohibited.
