Question

RAM is called volatile memory because

• A. It stores data permanently
• B. Data is lost when power is off
• C. It is slow
• D. It is expensive

Hint:

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

Answer 1

The Correct Option is B

Step 1: Recall the definition of volatile memory. Volatile memory requires continuous power to retain stored data.

Step 2: Identify the correct reason. When the power supply is switched off, \[ \boxed{\text{All stored data is lost}.} \] Therefore, RAM is called volatile memory. Hence, \[ \boxed{(B)} \] is the correct answer.
