Which component is primarily used for temporary storage during program execution?

• A. ROM
• B. RAM
• C. Hard disk
• D. CD-ROM

Answer: (B)

Temporary storage during program execution is provided by RAM. This fast, volatile memory serves as the workspace where the CPU keeps the active program’s instructions and the data it’s currently using. Because RAM is volatile, its contents disappear when power is turned off, which is fine because it’s meant for quick, short-term access rather than long-term retention. ROM, on the other hand, stores firmware and isn’t used for temporary work—it’s non-volatile and read-only. A hard disk offers long-term storage for files and programs and is much slower to access than RAM. A CD-ROM is also a form of persistent storage, typically used to hold data permanently or semi-permanently and not for the immediate working set. So RAM is the component designed for the quick, temporary storage the CPU uses while a program runs.
