Last updated Jun 23, 2026
Correct Answer:
Option C —
SRAM
The Principle: ROM (Read-Only Memory)
ROM is a type of non-volatile storage, meaning it retains its data even when the power is turned off. It is specifically designed for software that is "permanent" or rarely needs modification.
Fixed Instruction Storage: ROM is typically used to store firmware, such as the BIOS (Basic Input/Output System) of a computer, which contains the essential instructions needed to boot up the hardware.
Immutability: Unlike RAM or Flash, traditional ROM is hard-wired during manufacturing. This makes it the most reliable choice for software that must remain exactly the same throughout the life of the device.
Cost and Security: It is cost-effective for mass-produced devices (like simple calculators or microwave controllers) and provides a layer of security because the software cannot be easily altered or corrupted by viruses.
