Week 01 Tutorial Questions

    Welcome to COMP1511

  1. Introduce yourselves, get to know your tutor, get to know your classmates.

  2. How do you make a peanut-butter sandwich?

    How could you break that process into steps?

    How could you break it down clearly enough that a computer could understand it?

    Maybe your tutor could do a live demonstration of a similar task following your exact instructions...

  3. Your tutor will now take a few minutes to go over features of Blackboard Collaborate (recordings, raising hands, doing polls, and sharing screen)

  4. Do you have any questions about the course so far? eg course website, structure, assessments?

    5. Operating Systems

  5. What is an operating system?

  6. What operating system do you run? What about your classmates? The CSE lab (and VLAB) computers?

  7. What are the differences between graphical user interfaces and the command line? When might one be better than the other?

      ./face0

  10. How would you compile this program?
