What is Amdahl's Law primarily used for in computing? To predict maximum speedup from parallelization To determine the energy consumption of processors To calculate network bandwidth To evaluate memory usage efficiency

To predict maximum speedup from parallelization

Which of the following represents the mathematical formula for Amdahl's Law? \[ S \] = \[ rac{1}{(1-P) + rac{P}{N}} \] \[ S \] = \[ rac{1}{1-P} \] \[ S \] = \[ P imes N \] \[ S \] = \[ N - P \]

\[ S \] = \[ rac{1}{(1-P) + rac{P}{N}} \]

What is the primary limitation of Amdahl's Law? It does not consider communication overhead It assumes infinite processors It ignores memory constraints It overestimates parallel efficiency

It does not consider communication overhead

What does the variable \[ P \] represent in Amdahl's Law? The fraction of the program that can be parallelized The number of processors used The total execution time The sequential execution time

The fraction of the program that can be parallelized

In the context of Amdahl's Law, what happens as the number of processors approaches infinity? Speedup approaches \[ rac{1}{1-P} \] Speedup becomes infinite Speedup equals 1 Speedup is determined by network latency

Speedup approaches \[ rac{1}{1-P} \]

What does the bitwise AND operation do? Sets each bit to 1 if both bits are 1 Sets each bit to 1 if one of the bits is 1 Inverts all the bits Shifts bits to the left

Sets each bit to 1 if both bits are 1

How does a bitwise OR operation function? Sets each bit to 1 if both bits are 1 Sets each bit to 1 if one of the bits is 1 Sets each bit to 0 if both bits are 0 Shifts bits to the right

Sets each bit to 1 if one of the bits is 1

How does the bitwise AND operator function between two bits? If both bits are 0, the result is 1 If both bits are 1, the result is 1 If at least one bit is 1, the result is 1 The result is always 1

If both bits are 1, the result is 1

What is a common application of the bitwise XOR operator in data manipulation? Checking odd or even numbers Swapping two variables without a temporary variable Incrementing a binary number Multiplying two numbers

Swapping two variables without a temporary variable

Which operation can be used to clear a specific bit in a binary number? Bitwise OR with all 1s Bitwise AND with all 0s Bitwise XOR with 1 Bitwise AND with a mask of 0s except the target bit

Bitwise AND with a mask of 0s except the target bit

How can bitwise operations be used in string processing? By encoding characters into binary By reversing string order By counting characters By sorting strings alphabetically

By encoding characters into binary

What does the bitwise AND operator do? Sets each bit to 1 if both bits are 1 Sets each bit to 1 if at least one bit is 1 Sets each bit to 1 if only one bit is 1 Inverts all bits

Sets each bit to 1 if both bits are 1

What is a common use of a 2D array in string operations? Storing integer values Managing a collection of strings Performing calculations Drawing graphics

Managing a collection of strings

How does strcmp determine the result when comparing two strings? By length of strings By comparing characters lexicographically By memory address By number of vowels

By comparing characters lexicographically
