Which memory type is used to make a section of main memory read-only?

• A. Cloud Storage
• B. ROM (Read Only Memory)
• C. Data Processing
• D. RAM (Random Access Memory)

Answer: (B)

Understanding memory types and how they behave helps explain this. Read Only Memory, or ROM, is designed to hold data that isn’t meant to change during normal operation. It is non-volatile, so its contents stay even when the power is off, and the system can read from it but not (typically) write to it easily. That makes ROM ideal for storing firmware or essential startup instructions, creating a read-only area in the system’s memory map. In contrast, RAM is volatile and writable, meaning the data is lost when power is removed and the system uses it for active work. Cloud storage is external, not a primary memory type within the computer’s main memory, and data processing isn’t a memory type. So, ROM is the memory type used to provide a read-only section in the system.
