Which term describes nonvolatile memory that can be erased electronically and rewritten?

• A. Nonvolatile memory that can be erased electronically and rewritten
• B. RAM
• C. BIOS
• D. Cache

Answer: (A)

Nonvolatile memory that can be erased electronically and rewritten describes EEPROM— Electrically Erasable Programmable Read-Only Memory. It keeps data without power and can be erased and reprogrammed with electrical signals, which is why it’s used for firmware updates and small data storage. RAM is volatile, so it loses data when the power is off. BIOS refers to firmware stored in ROM or flash memory, not typically rewritten during normal operation. Cache is a small, very fast memory used by the CPU and is usually volatile. So the term in question aligns with EEPROM (and its common form, flash memory).
