BIOS stands for?

• A. Basic Input/Output System
• B. Binary Input/Output System
• C. Basic Integrated Operating System
• D. Basic Input/Operator System

Answer: (A)

BIOS stands for Basic Input/Output System. It’s firmware stored on the motherboard that runs when you power up a computer. Its job is to initialize hardware components (like the CPU, memory, storage controllers, and peripherals), perform the Power-On Self-Test to verify basic hardware is working, and provide basic services that the operating system uses to start up and interact with hardware. It isn’t a binary-focused system, an operating system, or an operator system, which is why the other expansions don’t fit. In modern systems you’ll see UEFI as the more advanced successor to BIOS, but BIOS remains the familiar term for that initial set of startup routines.
