Course Description

The emphasis of this course is on understanding the Internet protocols. The course will follow the textbook and take a top down approach. The students will understand the layered architecture of the Internet protocol stack and the important protocols which make the Internet work such as TCP, IP, and DNS. They will understand the various service models supported by the Internet and the applications such as WWW and Internet email which use them. The course will also cover various LAN technologies and Internet hardware such as routers, switches and hubs. If time permits, topics on multimedia applications, Internet security, and network management will also be covered.

Policy on Cheating

Any incidence of cheating in this class will be severely dealt with. This applies to homework assignments, programming assignments, quizzes and tests. The minimum penalty for cheating will be that the student will not obtain any credit for that particular assignment. (This means that if in a test and/or assignment a student is found have cheated, he/she will obtain zero in that test and/or assignment.) For the homework and the programming assignments students may discuss the problems with others, but one is expected to turn in the results of one's own effort (not the results of a friend's efforts). One tends to get very suspicious if two identically wrong results show up in the homework assignment and/or tests. The names of the offenders will be maintained in the departmental files. The repeat offenders may be debarred from the University.
