6. How to Take this Course? Don’t assume the instructor has answers to all the questions The instructor will cover only the general aspects of networking You need to be self-motivated and find answers on specific topics by yourself and share them with others (meaning you have to do a lot of homework although no homework is assigned) There is no textbook for this course. You need to search for references by yourself, as part of the homework
