Answer 2

The correct answer is (c) Parallel processing elements.

• Amdahl's regulation expresses that the max speedup conceivable in parallelizing a calculation is restricted by the consecutive piece of the c o d e.
• Given a calculation which is P% equal, Amdahl's regulation expresses that:

                             Maximum Speedup=1/(1-(P/100)).

• For example, on the off chance that 80% of a program is equal, the greatest speedup is

                                           1 / (1-0.8) = 1 / 0.2 = 5

• Since certain bits are in every case still consecutive, the advantages of adding more processors will go down, and at last the speedup arrives at a breaking point.
