IPA IP 2022 Question 84
A question IPA Japan published in 令和4年度 ITパスポート試験 公開問題 問84, translated into English. ITPEC is based on the same exams.
Same question on ITPEC: Apr 2025 Q12
Which of the following is a type of device that is also used as a memory device in IoT devices, and has a lower power consumption and higher impact resistance than an HDD as it has memory media that is made of semiconductors and does not have any moving components?
Explanation
SSD — a solid-state drive stores data in flash memory, a semiconductor, with no moving parts.
An HDD reads and writes with a head moving over spinning magnetic platters, which costs power for the motor and can be damaged by a shock. An SSD keeps the data in non-volatile flash memory chips, so it has no motor or head: it draws less power, is more resistant to impact and accesses data faster. This makes it a common storage device in IoT devices, smartphones and laptops.
Answer (d)
Why not others:
- •(a) DRM — Digital Rights Management, technology that controls copying and use of digital content, not a device
- •(b) DVD — an optical disc read by a laser in a drive that spins the disc, so it has moving parts
- •(c) HDMI — an interface standard for sending digital video and audio to a display, not a storage device
Key rule: Flash-based storage (SSD, USB memory, SD cards) is non-volatile, silent and shock-resistant because nothing moves; HDDs and optical drives rely on spinning media.
