This page provides you with 20 MCQs of BIOS (Basic input output system) that is very useful for many exams.
BIOS
- Bios stored on the ROM Chip.
- BISO helps to start the computer
- BIOS is the First Software to on the computer.
- Related to BIOS Setting all the information is stored on the CMOS.
- CMOS (complementary Metal oxide semiconductor) is the battery to helps basic information (date and time) be saved.
Q.1 BIOS stands for?
Basics input output System
Basic input output System
Basic input outcome System
None of these
Explanation
BIOS stands for Basic Input/Output System, which is the firmware used to perform hardware initialization during the booting process.
Q.2 Where is the BIOS stored?
ROM
RAM
HDD
None of these
Explanation
The BIOS is typically stored on a Read-Only Memory (ROM) chip on the motherboard so it is available even when the power is off.
Q.3 What is another name for the BIOS?
Drivers
POST
Firmware
None of these
Explanation
BIOS is a type of firmware, which is a specific class of computer software that provides the low-level control for the device’s specific hardware.
Q.4 what does POST stand for?
Post on self Test
Power on self Test
Power on section Test
None of these
Explanation
POST stands for Power-On Self-Test, a diagnostic testing sequence that the computer’s BIOS runs to determine if the computer hardware is working correctly.
Q.5 Which chip can be reprogrammed to update its contents?
ROM
Flash ROM
RAM
None of these
Explanation
Flash ROM can be electronically erased and reprogrammed, allowing for ‘BIOS updates’ to add features or fix hardware bugs.
Q.6 Where do modern PCs store CMOS settings?
RAM
Flash ROM
HDD
None of these
Explanation
While traditionally stored in battery-backed CMOS RAM, modern PCs often store these configuration settings in Flash ROM.
Q.8 Where should you look to interpret different beep codes?
Memory manufacturer
BIOS manufacturer
CPU manufacturer
None of these
Explanation
Beep codes are specific to the BIOS firmware, so you must consult the manual from the BIOS manufacturer to understand what specific beep patterns mean.
Q.9 Where is the POST process located?
ROM
BIOS
CPU
None of these
Explanation
The Power-On Self-Test (POST) instructions are part of the BIOS code stored in the ROM chip.
Q.10 The BIOS is a set of?
Instruction
Process
Execution
None of these
Explanation
The BIOS is essentially a collection of low-level software instructions stored on a chip.
Q.11 Is the BIOS considered a 'complete' software?
Yes
No
It may be
None of these
Explanation
The BIOS is technically considered firmware rather than a standalone software application, as it serves as a bridge between hardware and the OS.
Q.12 Which of the following is a main function of the BIOS?
POST
Bootstrap Loader
Drivers
All of these
Explanation
The BIOS performs the hardware test (POST), locates/loads the OS (Bootstrap Loader), and provides low-level drivers for hardware communication.
Q.13 What is modified when changing the system start-up boot sequence?
CONFIG.SYS
Bootstrap Loader
BIOS/CMOS
None of these
Explanation
Changing the order of boot devices (e.g., HDD vs USB) requires modifying the settings stored in the BIOS/CMOS configuration.
Q.14 Where are BIOS drivers stored?
CONFIG.SYS
Bootstrap Loader
ROM
None of these
Explanation
BIOS drivers are built into the ROM chip to allow the computer to communicate with basic hardware during startup.
Q.15 What is the primary use of the BIOS?
CONFIG.SYS
Bootstrap Loader
Operating System loading
None of these
Explanation
The most critical role of the BIOS is to initialize the hardware and facilitate the loading of the Operating System into RAM.
Q.16 What is Firmware?
Software that is part of Hardware
Software stored on a flash ROM
Combination of Software & Hardware
All of the above
Explanation
Firmware is a combination of hardware and software where the code is permanently or semi-permanently programmed into a hardware device.
Q.17 What is a part of the boot startup process?
Loads system files to ROM
Loads system files to RAM
Loads system files to HDD
All of the above
Explanation
During startup, the BIOS instructions in ROM are used to initialize the hardware and prepare the system.
Q.18 What is an example of an extension name related to the booting process?
Config.sys
autoexe.bat
booting.bt
All of the above
Explanation
AUTOEXEC.BAT was a standard file used by DOS systems during the boot process to set environment variables and run startup commands.
Q.19 A BIOS password can be used to protect the?
CMOS Setting
BIOS setup program
System at boot time
None of these
Explanation
A BIOS password restricts unauthorized access to the BIOS setup utility, preventing unauthorized hardware configuration changes.
Q.20 Software used to manage hardware interactions is known as?
Operating System
BIOS
System at boot time
None of these
Explanation
An Operating System is the primary system software that manages computer hardware and software resources.
