General Information

Course description:

This course covers TCP/IP network programming using Berkeley sockets as the application program interface. After an introduction to the concepts of computer networks, TCP/IP protocols, and sockets, TCP/UDP sockets and their example client-server programs are presented. The second half of the course covers advanced topics including I/O multiplexing, threads, non-blocking I/O, client-server design alternatives, etc. Along the semester, three mini-program assignments will be given. A mid-term exam and a final exam will be held to evaluate whether a student can use the taught network concepts and programming techniques to correctly develop his/her own network programs.

Prerequisite:

1. C (or C++) programming skills

2. Computer networks (highly preferred but not absolutely required)

3. Operating Systems (preferred but not absolutely required)

Lectures:

The course meets on Mondays from 3:30 pm to 4:20 pm and on Thursdays from 10:10 am to 12 pm, in EC 015 room.

Coursework:

Read the textbook
Write mini-programs homework (each student needs to write his/her own programs)
Take mid-term and final exams

Course Requirements:

40% Mini-programs homework
10% Class participation (Roll calls will be randomly conducted.)
25% Mid-term exam
25% Final exam

Exam Policies:

Because two cheating cases each using a cell phone were caught in the final exam of the “Introduction to Computer Networks” course of the 2020 school year, if cheating is caught in the mid-term or final exam in this course, the whole semester grade of the cheater will be set to 0.
When taking the mid-term exam or final exam, the cell phone of the student must not be placed on the table or is with the body of the student. It is required that the student should not bring his/her cell phone into the exam room. If the student still decides to bring his/her cell phone to the exam room, the cell phone must be placed inside a bag and must not be taken out during the whole exam. Otherwise, it is considered as cheating in the exam.
During the exam, if the student decides to go to the rest room, he/she must not take the cell phone with him/her. Otherwise, it is considered as cheating in the exam.

Coursework Policies:

· Late homework submissions will be punished.

o Every report/program demonstration should be submitted or performed by the deadline.

o The penalty for a late submission is: Its final score = its original score * (3/4) ^ #_late_days.

· Discussions are allowed and highly encouraged.

· However, when writing homework programs, “copy & paste” must not be used.

· Students’ homework programs will be sent to an online comparison system to detect whether or not “copy & paste” is used to make the programs. Once found, all involved students (including the students who let other students copy his/her program code) will get a score of 0 for this homework.
