Question

Which memory is volatile in nature?

• A. HDD
• B. SSD
• C. RAM
• D. USB Drive

Hint:

Memory types: \[ \boxed{ \begin{aligned} \text{RAM} &\rightarrow \text{Volatile}\\ \text{ROM, HDD, SSD, USB} &\rightarrow \text{Non-volatile} \end{aligned} } \]

Answer 1

The Correct Option is C

Step 1: Recall what volatile means.
A volatile memory loses everything stored in it the moment power is cut off.
Step 2: Rule out the storage devices.
HDD, SSD and USB drives are all designed to keep data safe even with no power, so none of them are volatile.
Step 3: Identify the one that needs constant power.
RAM only holds data while the system is powered on, and everything in it vanishes the instant power is lost.
\[ \boxed{\text{RAM}} \]
