Which memory type is described as data that cannot be modified after storage?

• A. ROM Read Only Memory
• B. RAM
• C. Pixel
• D. Real Time Imaging

Answer: (A)

ROM, or Read-Only Memory, is designed to hold data that remains fixed after it is stored. It is non-volatile, so it retains its contents without power, and normal operation does not allow rewriting the data. This makes it ideal for storing firmware and essential instructions that must not change during use. In contrast, RAM is writable and volatile—its contents disappear when power is off and it’s used for temporary work and processing. Pixel isn’t a memory type, and Real Time Imaging refers to a imaging mode, not storage. Therefore, data that cannot be modified after storage is stored in ROM.
