D)Kernel tables

Question

Quizplus · Accepted Answer

Hard drives have the least volatile data among the options given. Volatility in computing refers to the ability of a storage medium to retain data when the power is turned off. Hard drives, being non-volatile storage devices, retain data even when the power is turned off, unlike RAM (Random Access Memory) and CPU storage (such as registers and cache), which are volatile and lose their contents without power. Kernel tables, which reside in volatile memory during operation, also lose their data without power, making them more volatile than hard drives.
