Which term refers to non-volatile memory that is typically read-only?

• A. RAM
• B. SaaS
• C. ROM
• D. SATA

Answer: (C)

Non-volatile memory that is typically read-only is ROM. It keeps data even when power is removed, and it’s designed to be programmed once or only infrequently, so the information stored inside remains unchanged during normal operation. This makes ROM ideal for firmware and boot instructions that must be preserved across restarts and power cycles. RAM, by contrast, is volatile and loses data when power is off, so it’s used for temporary working memory. SATA is just a data interface for connecting storage devices, not a memory type. SaaS refers to software delivered over the internet, not memory.
