Which of the following statements about ROM contents is true?

The statement indicating that ROM contents are non-volatile is accurate because ROM, or Read-Only Memory, is specifically designed to retain its contents even when power is removed. This permanence is a critical characteristic of ROM, making it essential for storing firmware and essential system instructions that must be preserved across power cycles.

In contrast to ROM, volatile memory, such as RAM, loses its data when the power supply is interrupted. This distinction is fundamental in understanding the role of different types of memory in computing systems. Non-volatile memory like ROM ensures that critical data and instructions are always available for the system to function correctly after a reboot or power loss. Therefore, the reliability and stability of ROM make it a vital component in the architecture of computer systems.
