🧠Explanation:
BIOS stands for Basic Input Output System, a firmware that initializes hardware during a computer’s boot process. Stored on a motherboard’s chip, it manages basic operations like keyboard input and display output before the operating system loads. BIOS ensures communication between hardware and software, performing power-on self-tests to check system components. Essential for starting computers, it’s found in PCs and laptops, providing a foundation for system functionality. Modern systems may use UEFI, but BIOS remains a key term in computing history and functionality.
