Correct Answer:
Option D —
ROM
Why is Firmware Stored in ROM?Firmware is a specific type of software that provides low-level control for a device's specific hardware. Unlike standard software, it needs to be available the moment a device is powered on, before the operating system even loads.
Non-Volatility: ROM is non-volatile, meaning it retains its data even when the power is turned off. If firmware were stored in RAM, the device would "forget" how to boot up every time you shut it down.
Startup Instructions: In computers, the BIOS or UEFI is a prime example of firmware. It resides on a ROM chip (usually an EPROM or Flash memory) on the motherboard and tells the computer how to initialize hardware and find the boot drive.
Security and Stability: Historically, storing firmware in Read-Only Memory prevented accidental erasure or corruption by the user or malicious software, ensuring the device remains functional.
