Telecommunication Quizzes & Trivia

The following questions are derived from the information that is in Ch. 4, 5, 8 of the powerpoint. Although the exam will most definitely look different, the following questions cover material that we'll be tested on, on Monday. Also, at the end I list some of the UNIX commands that we talked about on Friday.
