Memory in which contents are permanent and cannot be altered; the bit pattern is burnt.

Memory in which contents are permanent and cannot be altered; the bit pattern is burnt.

• A. RAM
• B. ROM
• C. Memory
• D. Verification (data input)

Answer: (B)

This describes ROM. It’s non-volatile memory, meaning it retains data without power, and in its typical form the data are permanently set and cannot be changed during normal use. The phrase “bit pattern is burnt” refers to programming done at manufacture (or a one-time programmable form like PROM), so the contents remain fixed. RAM, by contrast, is volatile and loses its data when power is removed. The term memory is too general, and “Verification (data input)” isn’t a memory type at all.
