[SOLVED] CS 159.342 Final Exam Coverage (2022)

159.342 Final Exam Coverage (2022)
The exam is an Open Book Time-Constrained Assessment and will be conducted online (via our Stream website).Nopart of the examination may be captured, retained or shared for any purpose other than completing and submitting the questions and answers for marking. Doing so would constitute cheating and appropriate penalties will apply.
To help the class focus their preparation for the exam, I would like to identify some of the topics we have covered, especially those that require computations.
The exam type is a combination of fill-in the blanks and multiple-choice types, and the class will be given 3 hours to complete it.

Some exam questions will involve hand-simulation of the different protocols and algorithms that we have covered in the course, and so it would be good to do some practice, solving those examples provided in the lectures/tutorials, to prepare for the exam.On the other hand, some questions will involve basic concepts, architectures, and terminologies.No actual programming is required in the exam, but questions may involve socket functions, their purpose and relation to networking technologies and protocols.
To get acquainted with how questions are typically formulated, have a look at the past exams (from 159334 and 159335) posted in this section.Take note that 159.342 contains a selection of topics from 159334 and 159335, but not all of them are covered.The scope of the exam is only up to what was covered in the lectures.Our final exam will be comprised of a combination of multiple-choice and fill-in the blank types of questions.I am providing herewith a list of topics that are within the scope of our exam.I have highlighted (in blue) those topics that involve some algorithms/protocols, thus requiring some computations.
