What does BIOS stand for?

• A. Basic Input/Output System
• B. Bits Per Second
• C. Binary Input/Output System
• D. Basic Integrated Operating System

Answer: (A)

BIOS stands for Basic Input/Output System. It’s the firmware on the motherboard that runs when you power up a PC, performing the Power-On Self-Test, initializing hardware, and providing the first layer of communication between the CPU and devices before the operating system loads. It lives on a ROM/flash chip and stores settings in CMOS memory, which you can configure in the BIOS setup utility. The other options don’t fit because they describe data rate (bits per second), or are not the standard terms used for this firmware function.
