question 69

Multiple Choice

What problem is faced by multicore processors running older software written for single-brain chips?

• A) Multicore processors usually run older software by using only one core at a time.
• B) Multicore processors draw more power than single-brain processors to solve the same problem.
• C) Multicore processors require greater cooling to run the same software as single-brain processors.
• D) Individual cores in multicore processors have smaller memories than single-brain chips and are consequently slower.
• E) Multicore processors still have some fair distance to go before going mainstream.

Definitions:

Two-Tail Test

A statistical test in which the critical area of a distribution is two-sided and tests whether a sample is greater than or less than a certain range of values.

Critical Values

Specific points on the scale of a statistical distribution that are associated with a specified significance level, used for hypothesis testing.

Rejection Regions

Specific areas in the distribution of a test statistic that, if the observed test statistic falls within, will lead to the rejection of the null hypothesis.

Standardized Test Statistic

A calculated statistic that measures the number of standard deviations a sample statistic lies from the null hypothesis, used in hypothesis testing.
