FC0-U71 Practice Question: Which type of computer memory loses its data when…
Which type of computer memory loses its data when the power is turned off?
⚠ Common exam trap
A common mix-up: candidates confuse 'memory' with 'storage' and mistakenly think HDDs or SSDs lose data on power loss, or they assume ROM is volatile because it is 'read-only' and cannot be easily modified.

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
✓
RAM
RAM (Random Access Memory) is volatile memory, meaning it requires continuous electrical power to retain data. When the power is turned off, the electrical charges in the memory cells dissipate, causing all stored data to be lost. This is why RAM is used for temporary storage of actively running programs and data.
