Question

what is the most common type of volatile memory?
○ a. flash memory
○ b. random access memory (ram)
○ c. hard disk
○ d. read-only memory (rom)

Explanation:

To solve this, we analyze each option:

• Option a: Flash memory is non - volatile (retains data without power), so it's incorrect.
• Option b: Random Access Memory (RAM) is volatile, meaning it loses data when power is off, and it's the most common type of volatile memory in computers for temporary data storage during operation.
• Option c: A hard disk is a non - volatile storage device (stores data long - term), so it's incorrect.
• Option d: Read - Only Memory (ROM) is non - volatile (retains data like firmware even without power), so it's incorrect.

Answer:

b. random access memory (RAM)
