Question

4. Corresponding to Exercise 1 on page 203: • One friend claims that a dual-core system runs at twice the speed as a single-core system; the second friend disagrees by saying that it runs twice as many programs at the same time; and the third friend says it runs twice as much data at the same time. Explain who is correct and why. You MUST give a rationale for EACH friend’s statement. Note that one friend may be partly correct. Nonetheless, you still have to provide a rationale for each. • This question is worth 10% of the assignment, with the answer for each friend being worth 3.33%. Friend Is the Friend Correct, Incorrect, or Partly Correct, and Why 1 2 3

Explanation / Answer

Answer is as follows :

The third friend would be correct that a dual core system would run twice as much data at the same time because dual core systems are not faster than single core systems due to the extra core. The speed of a dual-core system usually depends on the tasks that are within the system and if they are multi threaded or sequential. Dual core systems may allow twice as much data a the same time and it also generates less heat than a single core and reduce tunnelling effects.

Now as described above the dual core systems are not faster than single core systems so the friend one is completely wrong.

The second friend is partially correct because dual core emphsizes on data not the programs on the same time.

Now the conclusion is :

First Friend = Comptely Incorrect

Second Friend = Partially Correct

Third Friend = Fully Correct
