Volatility concept: Memory that loses its contents as soon as power is removed is classified as what type of memory?

Introduction / Context:
Understanding volatility is essential when deciding where to store code versus runtime data. Volatile memory is used for temporary working data; nonvolatile memory stores information that must survive power cycles.

Given Data / Assumptions:

• Focus on behavior upon power loss.
• Examples: DRAM and SRAM are volatile; Flash/EEPROM are nonvolatile.
• Terminology “static” in SRAM does not mean nonvolatile; it means no refresh while powered.

Concept / Approach:
Volatile memory requires continuous power to maintain stored information. Once power is removed, its contents decay or reset to an undefined state. This is why systems reload code from nonvolatile storage (e.g., Flash) into volatile RAM during boot for fast execution.

Step-by-Step Solution:

Verification / Alternative check:
Observe any PC: RAM contents are lost when shut down; OS and firmware persist in Flash/ROM.

Why Other Options Are Wrong:

• Nonvolatile: Opposite behavior.
• Random: Refers to random access, not retention.
• Static: Describes refresh behavior of SRAM, not retention without power.

Common Pitfalls:
Misinterpreting “static” as nonvolatile; static RAM is still volatile.

Final Answer:
volatile
