Attempted by 29 students.
Show answer & explanation
Correct answer: D
The Bathtub Curve is used in Hardware Reliability Engineering to represent the failure rate of hardware components over their lifetime.
Three Phases of the Bathtub Curve
1. Infant Mortality Phase
High failure rate at the beginning.
Caused by manufacturing defects.
2. Useful Life Phase
Low and nearly constant failure rate.
Hardware operates normally.
3. Wear-Out Phase
Failure rate increases with age.
Due to component aging and wear.
Since the Bathtub Curve describes hardware failure behavior over time, the correct answer is:
Answer: D) Hardware Failure Rate
