BIOS EXAM QUESTIONS WITH CORRECT ANSWERS LATEST UPDATE 2026
BIOS - Answers Basic Input/Output System
A set of computer instructions on firmware which control input and output operations. BIOS is non-
volatile firmware used to perform hardware initialization during the booting process (power-on
startup), and to provide runtime services for operating systems and programs
CMOS - Answers Complementary Metal-Oxide Semiconductor
Technology used by some RAM chips, flash memory chips, and other types of memory chips that
provides high speeds and consumes little power by using battery power to retain information even
when the power to a computer is off.
UEFI - Answers Unified Extensible Firmware Interface.
An interface between firmware on the motherboard and the operating system that improves on
legacy BIOS processes for booting, handing over the boot to the OS, and loading device drivers and
applications before the OS loads. It also manages motherboard settings and secures the boot to
ensure that no rogue operating system hijacks the system.
The main functionality of the Basic Input/Output System (BIOS) is to perform the initial hardware
checks after the computer is powered on and start up the operating system.
True or False - Answers True
POST - Answers Power(ed) On Self Test
A hardware check preformed at startup by the BIOS, it sends out a command to all the hardware
devices to check themselves. All of the devices then run their own built-in diagnostics designed by
their manufacturers.
