Which of the following actions will cause data stored within an EEPROM chip to be erased?
A. Submerging the motherboard traces into a grounding solution.
B. Shutting down the central computer system power switch.
C. Exposing the chip face to high-intensity ultraviolet light rays.
D. Applying a designated electrical voltage signal to the chip control pins.
Answer: Option D
Solution (By JKSSB Mock Tests)
EEPROM stands for Electrically Erasable Programmable Read-Only Memory. It is erased and rewritten digitally by applying specific electrical currents to its pins.
Explanation:
DRAM (Dynamic RAM) uses capacitors to store bits; they leak charge and must be refreshed periodically. SRAM uses flip-flops and does not need refreshing.
Explanation:
Secondary storage (hard disks, SSDs, tapes) is used for long-term, large-capacity data storage, while primary storage (RAM) is volatile and temporary.
Explanation:
ROM is non-volatile and retains data without power. However, for long-term storage, hard disks and SSDs are more common; ROM is typically used for firmware. Among the options, ROM is non-volatile.
