CompTIA A+ (220-901) — Question 30

A customer wants a computer for performing a single-threaded task as quickly as possible. Which of the following CPU characteristics is the MOST important?

Answer options

• A. Clock speed
• B. Hyperthreading
• C. Fan speed
• D. Number of cores

Correct answer: A

Explanation

The correct answer is A, as higher clock speeds directly enhance the performance of single-threaded tasks by allowing more instructions to be processed per second. Hyperthreading (B) and the number of cores (D) are more beneficial for multi-threaded applications, while fan speed (C) does not affect processing capability.
