Regarding Chapter 3:

1. What are the special requirements for supporting continuous media with a multimedia system?
   
2. Explain QOS and parameters used to measure it.
   
3. How do the following relate to QOS: best effort, admissibility, scheduling, synchronization, guarantees?
   
4. What are the key approaches to guaranteeing QOS?
   
5. What is the Lancaster Univ. QOS Architecture all about?
   
6. What are ST II and RTP for? How do they relate to videoconferencing over the Internet?

1. Explain how authoring and presentation systems differ.
   
2. Contrast traditional programming, visual programming, timeline and iconic approaches to authoring.
   
3. Explain the tradeoffs of power and ease of use in authoring systems.
   
4. How do the popular interfaces or systems for authoring differ?
   
5. What are the key barriers to successful use of authoring and presentation systems? What are the real problems and can they be solved?
   
6. What the the important trends in research into authoring systems? What benefits are likely to result?

1. Explain the function of each of the following Authorware icons:
   
   
   • Display Icon
     
   • Erase Icon
     
   • Calculation Icon
     
   • Interaction Icon
     
   • Decision Icon
     
   • Map Icon
     
   • Sound Icon
     
   • Movie Icon
   
   
2. How does Authorware provide code modularity? (Hint: What icon is involved?)
   
3. Compare/contrast Authorware to "traditional" programming languages (consider how program flow occurs, icons versus program language statements, etc., code modularity). What are the advantages/disadvantages of Authorware?
   
4. Explain how a Calculated Path Icon controls program branching.
   
5. Explain how a Conditional Response can affect program execution (when it is present on an Interaction icon's flowline.)
   

   Note: Since Authorware is such an important part of this unit, you should expect 2-3 questions on it in the Quiz.
