Question 63 CEL02 - Chief Engineer - Limited (Alt)

The Correct Answer is B **Explanation for Option B (Correct):** Option B is correct because it accurately defines the primary characteristic of Random Access Memory (RAM). RAM is a type of computer memory that requires power to maintain the stored information; this property is known as **volatility**. If the power supply is interrupted or removed (e.g., when the computer is shut down), the electrical charge used to store the data quickly dissipates, and the contents of the RAM are entirely lost. **Explanation for Other Options (Incorrect):** * **A) RAM is non-volatile memory and the contents of RAM are lost when the power is removed.** * This is incorrect because it contains a contradiction. If memory is non-volatile, the data is *not* lost when power is removed (e.g., Solid State Drives or ROM). RAM is volatile, making the first part of the statement false. * **C) RAM is non-volatile memory and the contents of RAM are not lost when the power is removed.** * This statement defines non-volatile memory (like ROM or flash memory), not RAM. RAM is volatile, meaning the data *is* lost when power is removed. * **D) RAM is volatile memory and the contents of RAM are not lost when the power is removed.** * This is incorrect because it contains a contradiction. If memory is volatile, the data *is* lost when power is removed. The two parts of the statement negate each other.
