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:

Allele Frequencies

A measure of the relative frequency of an allele (variant of a gene) at a genetic locus in a population, expressed as a proportion or a percentage.

Directional Selection

The gradual replacement of one phenotype with another because of environmental change that favors phenotypes at one of the extremes of the normal distribution. Compare with stabilizing selection and disruptive selection.

Phenotypes

The set of observable characteristics or traits of an organism resulting from the interaction of its genotype with the environment.

Normal Distribution

A bell-shaped frequency distribution curve, where most occurrences take place in the middle of the distribution and taper off on either side.
