When does the computer clear RAM memory?

• A. When a program is closed
• B. When the computer is turned off
• C. When the computer is restarted
• D. When a file is saved

Answer: (B)

The correct answer indicates that RAM memory is cleared when the computer is turned off. This is because RAM (Random Access Memory) is a type of volatile memory, meaning it temporarily stores data and information that is actively being used by the CPU. Once the power is removed, such as when the computer is shut down, all data within RAM is lost.

In contrast, data stored on non-volatile memory sources, like hard drives or solid-state drives, remains intact even when the power is turned off. Other options involve actions or conditions where data may still persist in RAM. For example, when a program is closed or a computer is restarted, the contents of RAM may change or be altered, but the memory does not become wholly cleared until the power is cut off. Saving a file simply transfers data from RAM to permanent storage without affecting the volatile nature of RAM itself. Thus, the unique characteristic of RAM as volatile memory clarifies why the memory is cleared specifically when the computer is turned off.
