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

• A. Output Device
• B. ROM (Read Only Memory)
• C. Secondary Memory
• D. Cookies

Answer: (B)

The main idea here is memory types and how data is stored and protected. ROM stands for Read Only Memory and is designed to be non-volatile and not modified during normal operation. That’s why it’s used to hold instructions or data that should remain fixed, effectively making a section of main memory read-only. In contrast, an output device is just for displaying results, not storing memory. Secondary memory refers to long-term storage like hard drives or SSDs, which are writable and not part of the active main memory. Cookies are browser-stored data, not hardware memory.
