One advantage of DES is its efficiency

Answer the following statements true (T) or false (F)

1. A circular array eliminates rightward drift. 2. Using a front and back pointer in a circular array will indicate whether a queue is empty or full. 3. Using the ADT list to represent a queue is not as efficient as using a linked chain directly. 4. It is poor design to use a sorted list to contain the entries of a priority queue. 5. The enqueue and dequeue operations for a queue require efficient access to both ends of the queue. 6. If you use a circular array to implement a queue, you must be able to distinguish between the queue-full and queue-empty conditions.

Which of the following statements is false?

a. Thread scheduling is platform independent. b. One simple thread-scheduler implementation keeps the highest-priority thread running at all times and, if there’s more than one highest-priority thread, ensures that all such threads execute for a quantum each in round-robin fashion. c. The round-robin process for all highest-priority threads continues until all threads run to completion. d. Most programmers who use Java multithreading will not be concerned with setting and adjusting thread priorities
