Do ROM chips lose their contents when the power is turned off?

• A. Yes, they do
• B. No, they retain their contents
• C. Only under specific conditions
• D. Only if a reset occurs

Answer: (B)

The correct answer is that ROM chips retain their contents when the power is turned off. This characteristic is fundamental to the operation of Read-Only Memory (ROM). ROM is designed to hold data permanently, which allows it to store firmware or the software that initializes hardware during the boot process of a device. Unlike Random Access Memory (RAM), which is volatile and loses its data when power is removed, ROM is non-volatile. This means that the information written to ROM is preserved even without power, making it crucial in scenarios where data integrity during power outages is important. As a result, the contents of ROM chips remain intact until they are intentionally reprogrammed or rewritten, which is a process that typically occurs less frequently compared to the read/write operations in RAM. Other choices may imply conditions under which data might be lost, but in the case of standard ROM, those scenarios do not apply since the fundamental design of ROM is meant to securely retain information regardless of power status.
