Answer 1

ANSWERS -

A. (4) Performance via parallelism

It performs operation or task in a parallel way in order to get high performance. It matches with the railway lane which operates in a dual track model.

B. (1) Design for Moore's law

C. (2) Use abstraction to simplify design

It hides the internal details and offers only the essential information or simpler models. It matches with the eyeglass example where thousands of design activity takes place but the final product is only small pair of eyeglasses.

D. (7) Hierarchy of memories

E. (6) Performance via prediction

In this idea, the performance is enhanced if guesses and prediction are accurate, if it turns to be wrong then also the penalty is not that severe.

F. (8) Dependability via redundancy

The computer should be dependable, the system should contain a redundant component so that even if one device or component fail, it should overcome that failure and detect that cause of failure.

G. (3) Make the common case fast

This idea is to enhance the performance of common case than that of the rare case.

H. (5) Performance via pipelining

It is similar to performance via parallelism, in pipelining it improves performance by increasing instruction throughput and it has sequence of pipes where each section represents each stage of pipeline. The application of car assembly plant matches where there are different stages and in each stage one stage is overlapped by another.

So, the correct answers are A - 4 , B - 1, C - 2, D - 7, E - 6, F - 8, G - 3, H - 5.
