Which memory type provides fast, temporary storage that is erased when the computer is turned off?

• A. ROM
• B. RAM
• C. Software
• D. Input

Answer: (B)

Fast, temporary storage that disappears when power is removed is provided by RAM. RAM, or Random Access Memory, is volatile, meaning it needs power to keep data. The CPU uses RAM as working memory to store data and instructions while programs run, so everything here is quickly accessible but wiped when you shut the computer off. ROM, by contrast, is non-volatile and holds firmware that stays even without power, so it isn’t used for the temporary workspace. Software refers to programs, not a memory type, and input describes data or signals from outside the computer, not memory either. So RAM is the best choice.
