Question

question 8 of 10
which two statements help explain why digital storage of data is so reliable?

a. as copies are made, the copied data decrease in quality.

b. even if a storage device breaks, data on its memory chips can usually be recovered.

c. different amounts of digital data can be stored on different chips.

d. memory chips are sturdy and do not break easily.

Explanation:

• Option A is incorrect because digital copies do not lose quality, which is a key reliability feature, so this contradicts the question.
• Option B is correct: Data recovery from damaged storage device chips is a core reason digital storage is reliable, as it mitigates data loss from hardware failure.
• Option C is irrelevant: The variable storage capacity of different chips does not explain reliability, only storage scalability.
• Option D is correct: Sturdy, damage-resistant memory chips reduce the risk of physical failure that would cause data loss, enhancing reliability.

Answer:

B. Even if a storage device breaks, data on its memory chips can usually be recovered.
D. Memory chips are sturdy and do not break easily.
