FC0-U71 Tech Concepts and Terminology Practice Question
A technician is troubleshooting a computer that does not start. They suspect the BIOS may be corrupted. Which type of software is the BIOS?
⚠ Common exam trap
The trap is that candidates may think BIOS is an operating system because it manages boot, but the exam expects you to recognize it as firmware due to its storage on a chip and low-level hardware control.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Firmware
The BIOS (Basic Input/Output System) is firmware — low-level software stored on a chip on the motherboard that initializes hardware during boot and provides runtime services for the operating system. It is not an operating system, application, or device driver, though it is often confused with them due to its role in starting the system.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Operating system
Why it's wrong here
An operating system is loaded by the BIOS boot process, so it cannot itself be the BIOS firmware that runs first. It is tempting because both manage hardware and provide low-level services, but the BIOS resides in ROM on the motherboard and executes before any OS is present.
- ✗
Application software
Why it's wrong here
BIOS is firmware — low-level code stored in ROM/flash that initialises hardware before any operating system loads; application software runs atop an OS. It is tempting because BIOS ships as software, but its pre-boot, hardware-initialisation role places it in firmware, not applications.
- ✓
Firmware
Why this is correct
BIOS is firmware: low-level code stored in non-volatile ROM on the motherboard, executed before any operating system loads. This distinguishes it from application or system software, and explains why corruption prevents the machine from completing POST and starting.
- ✗
Device driver
Why it's wrong here
A device driver is software that lets the operating system communicate with a specific hardware component, so it cannot be the firmware that initialises hardware before any OS loads. It is tempting because drivers also sit between software and hardware, but they load after the OS, whereas BIOS runs from motherboard firmware at power-on.

Same concept, more angles
3 more ways this is tested on FC0-U71
These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.
Variation 1. A technician is troubleshooting a computer that fails to boot. The technician suspects corrupted firmware. Which component stores the firmware that initializes hardware during boot?
hard- A.RAM
- B.Hard drive
- ✓ C.ROM chip on motherboard
- D.CMOS battery
Why C: Firmware that initializes hardware during boot (BIOS/UEFI) is stored in a ROM chip on the motherboard, typically a flash EEPROM or SPI flash chip. This non-volatile memory retains the firmware even when power is removed, allowing the system to begin the boot process.
Variation 2. A technician is troubleshooting a computer that fails to boot. The technician checks the system's low-level software stored on a chip on the motherboard. Which type of software is being inspected?
medium- ✓ A.Firmware
- B.Device driver
- C.Application software
- D.Operating system
Why A: Firmware is low-level software stored on a chip (such as a ROM, EEPROM, or flash chip) on the motherboard that provides basic control of hardware and initializes the system during boot. The BIOS/UEFI is a prime example of firmware, so inspecting the chip on the motherboard means inspecting firmware. This is distinct from drivers, applications, and the OS, which reside on storage devices.
Variation 3. A technician is troubleshooting a computer that fails to boot. Which of the following types of firmware is responsible for initializing hardware and loading the operating system?
hard- A.Operating system kernel
- ✓ B.BIOS/UEFI
- C.Boot loader
- D.Device driver
Why B: BIOS (legacy) and UEFI (modern) are the firmware embedded on the motherboard that runs the Power-On Self-Test, initializes hardware components, and hands control to the bootloader to load the OS. This is the first code executed after power-on, making it the correct answer for 'responsible for initializing hardware and loading the operating system.'
