Volatile memory loses its data when the computer is turned off, while non-volatile memory retains its data.
Volatile memory is slower than non-volatile memory in data access.
Volatile memory is used for long-term storage, while non-volatile memory is used for temporary storage.
Volatile memory is more expensive than non-volatile memory.

Answer 1

The correct answer is Option 1: Volatile memory loses its data when the computer is turned off, while non-volatile memory retains its data.

Key Points

Volatile memory requires power to maintain the stored information.
When the power is turned off, all data stored in volatile memory is lost.
Non-volatile memory, on the other hand, does not require power to maintain the stored information.
Data stored in non-volatile memory is retained even when the power is turned off.

Important Points

Volatile memory is typically used for primary storage, such as RAM (Random Access Memory).
Non-volatile memory is typically used for secondary storage, such as hard drives, SSDs (Solid State Drives), and flash drives.
Examples of volatile memory include DRAM (Dynamic RAM) and SRAM (Static RAM).
Examples of non-volatile memory include ROM (Read-Only Memory), EEPROM (Electrically Erasable Programmable Read-Only Memory), and NVRAM (Non-Volatile RAM).
