FC0-U71 Tech Concepts and Terminology Practice Question
Which component of a computer stores data permanently even when the power is turned off?
⚠ Common exam trap
The trap is conflating fast memory (RAM, cache, VRAM) with permanent storage — candidates may pick RAM because it's commonly associated with 'computer memory,' forgetting it is volatile.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
SSD
An SSD (Solid State Drive) is non-volatile storage, meaning it retains data even when power is removed. It uses NAND flash memory to store data persistently, making it the correct answer for permanent storage. In contrast, CPU cache, GPU memory, and RAM are all volatile and lose their contents when power is cut.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
SSD
Why this is correct
An SSD uses non-volatile NAND flash memory, retaining stored data when power is removed, unlike DRAM which requires constant refresh. This non-volatile characteristic directly satisfies the stem's requirement for permanent data storage across power-off cycles.
- ✗
CPU cache
Why it's wrong here
CPU cache is SRAM sitting between the cores and main memory; it retains nothing once power is cut. It is tempting because cache is the fastest storage tier and holds frequently reused instructions, making it correct if the question asked where the processor keeps recently accessed data to cut latency.
- ✗
GPU
Why it's wrong here
A GPU holds only the frame buffer and shader data it is actively processing; that memory is volatile and cleared at power-off. It is tempting because GPUs contain dedicated VRAM for graphics workloads, which would be the right answer if the question asked which component accelerates parallel rendering or machine-learning computation.
- ✗
RAM
Why it's wrong here
RAM is volatile: its cells lose stored charge once power is removed, so contents vanish on shutdown. It is tempting because RAM is where active programs and working data reside during operation, making it the correct answer when a question asks which component holds data only while the computer is running.
