Q

What are the four main functions of the "BIOS" in most computers?

🔍 Key Concepts

• What the computer does immediately after you press the power button • What checks are done on hardware before the operating system loads (like RAM and basic devices) • Where very basic hardware control software is stored before any operating system drivers load

💭 Think About

• Which option lists only tasks that happen before the operating system starts loading? • Which items sound like low-level startup and hardware-check functions, not things you normally configure from inside Windows/macOS/Linux? • Which choice includes the power-on self-test, the initial loader for the OS, the tiny built‑in drivers, and the configuration menu for these settings?

✅ Before You Answer

• Identify which choice includes P.O.S.T. (Power-On Self-Test) and Bootstrap Loader together • Check which answers mention BIOS drivers (very basic built-in hardware routines) instead of high-level items like printer or USB drivers • Confirm that the four functions you select all happen before the main operating system is running
