Answer : 2. "in secondary storage"
Explanation :

The data remains the same after saving the file and turning off the computer when it is stored in secondary storage. Secondary storage devices, such as hard drives, solid-state drives, and optical discs, are non-volatile storage media. This means that they retain data even when the power is turned off. Unlike volatile memory (such as RAM), which loses its content when the computer is powered down, data stored in secondary storage remains intact until it is intentionally deleted or modified.

Answer : 4. "none of the above"
Explanation :

The key difference lies in when the loop condition is checked. In the while loop, the condition is checked before the first iteration, potentially resulting in zero iterations. In the do-while loop, the condition is checked after the first iteration, ensuring that the loop body is executed at least once.
