Mobile phones should be kept either switched-off or be kept on silent-mode Smoking No smoking policy in all classrooms and corridors of FUC 4 2

3 General comments There will be no labs! Course material is based on the lecture notes the main and recommended textbooks homework/exercises in class Attend Lectures!!! Don t be late, try to attend classes on the scheduled time May get an absence if delayed more than 5 minutes after scheduled time of lecture. Test and exam-relevant exercises will be given and discussed No more than 4 absences (30%), otherwise you may not be allowed to sit for final examinations 5 General comments Complete course material is available online download lecture notes and print them before each lecture from add your own comments during the lectures Check for the (New! uploaded on../../2008) sign: up-to-date material will be available the day before each lecture Material is a framework extra exercises/examples during classes need to study extra material in main and/or recommended textbooks if you miss a class then copy any comments from a fellow student 6 3

4 Course objectives to introduce computer science and computer engineering students to topics in data and computer communications to familiarize students with data communication principles such as the OSI and TCP/IP reference models and associated protocols, analogue and digital data transmission, transmission media, signal encoding and digital data communications techniques, data link flow and error control, multiplexing, circuit and packet switching 7 Students Assessment Final exam: 60% Coursework: 40% Allocated as follows: Test 1 (lectures 2-4): Test 2 (lectures 5-9): 8 4
