RAM vs ROM: which statement is correct about volatility and usage?

• A. RAM is non-volatile; ROM is volatile.
• B. RAM is slower than ROM.
• C. RAM is volatile and fast, used for temporary data; ROM is non-volatile, stores firmware, slower.
• D. RAM stores firmware; ROM holds working data.

Answer: (C)

Volatility and how each type of memory is used are what differentiate RAM from ROM. RAM is volatile, meaning it loses its data when the power is turned off, and it’s fast, making it ideal for the system’s temporary workspace where active programs and data reside while the computer is running. ROM is non-volatile, so it keeps its contents without power, and it’s typically used to store firmware—the essential instructions the machine needs to boot and initialize hardware. Because firmware doesn’t change often and needs to be kept reliably, ROM is slower to access compared to RAM. So the statement that RAM is volatile and fast, used for temporary data, while ROM is non-volatile, stores firmware, and is slower, best captures how these memory types function.
