Question

Which one is the primary memory device?

• A. ROM
• B. Floppy Disk
• C. DVD ROM
• D. HDD

Answer 1

Answer:

A. ROM

• ROM is a type of primary memory (along with RAM) that is directly accessed by the CPU.

• It holds essential boot instructions (like the BIOS/UEFI) and is non-volatile.

• Floppy Disk, DVD ROM, and HDD (Hard Disk Drive) are all secondary storage devices used for long-term data storage and are not directly accessed by the processor in the same way primary memory is.
