🧠 Explanation:
On boot-up, a computer’s first instructions come from ROM BIOS (Read-Only Memory Basic Input/Output System). Stored on a chip, BIOS initializes hardware and loads the operating system. It’s critical for starting a computer, ensuring components like the CPU and memory function. Understanding ROM BIOS is key in computer science, as it bridges hardware and software during startup. Its role highlights the foundational processes in computing, making it essential for tech enthusiasts and professionals studying system architecture or troubleshooting boot-related issues in modern devices.
