See also the day-by-day slides, where I will place the lecture slides as we use them throughout the quarter.

References to the text are to our required text, Computer Networking: A Top-Down Approach, 7th ed., James F Kurose and Keith W Ross, Pearson, © 2017. (6th edition © 2013.) You can see the differences between the editions in the front cover of the 7th edition, available at the MSOE bookstore. One difference that affects our class: The new version uses Python 3, the old version uses Python 2. Both editions include and explain Python code on about 6 pages, and it is the text's use of Python that prompted us to transition the whole course to the Python language. We will use Python 3 exclusively this quarter. If you hover over the required readings, it will show the reading in both the 7th and 6th editions of the text.
The labs are numbered by the week in which the lab is due during the lab period. Thus, the Week 2 Lab and Lab 2 are the same lab. I will avoid using terms like "The 1st lab" since there is no Lab 1, and it would be confusing to call Lab 2 the first lab.
