What is ROM?
ROM stands for read-only memory and refers to storage used for persistent low-level instructions or firmware in a device.
What it is
ROM is associated with data that stays available even when power is removed.
Why it matters
It is often discussed in relation to firmware, startup instructions, or low-level device behavior.
How to think about it
It matters because devices rely on persistent startup instructions and system-level code.

ROM in simple terms
ROM stands for read-only memory. It refers to memory that stores important data or instructions that are not meant to change frequently during normal operation.
How ROM is used
ROM has historically been used to store startup instructions, firmware-like data, and other essential information needed by hardware or systems before normal software loads.
ROM vs RAM
ROM is used for more permanent or semi-permanent instructions, while RAM is used as temporary working memory while programs and systems are running.
Why ROM matters
ROM matters because it helps systems preserve critical instructions even when power is removed.
