A)
ROM
B)
RAM
C)
HDD

None of these
Discuss it
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.
View Solution Q.3 What is another name for the BIOS?
A)
Drivers
B)
POST
C)
Firmware
D)
None of these
Discuss it
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.
View Solution Q.4 what does POST stand for?
A)
Post on self Test
B)
Power on self Test
C)
Power on section Test
D)
None of these
Discuss it
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.
View Solution Q.5 Which chip can be reprogrammed to update its contents?
A)
ROM
B)
Flash ROM
C)
RAM
D)
None of these
Discuss it
Explanation
Flash ROM can be electronically erased and reprogrammed, allowing for 'BIOS updates' to add features or fix hardware bugs.
View Solution Q.6 Where do modern PCs store CMOS settings?
A)
RAM
B)
Flash ROM
C)
HDD
D)
None of these
Discuss it
Explanation
While traditionally stored in battery-backed CMOS RAM, modern PCs often store these configuration settings in Flash ROM.
View Solution Q.7 CMOS stands for?
A)
Complementary metal–oxide–semiconductor
B)
Complementary meta–oxide–semiconductor
C)
Complementary metal–oxide–semicolon
D)
None of these
Discuss it
Explanation
CMOS stands for Complementary Metal-Oxide-Semiconductor, which is a technology used in microchips, including the one that stores BIOS settings.
View Solution Q.8 Where should you look to interpret different beep codes?
A)
Memory manufacturer
B)
BIOS manufacturer
C)
CPU manufacturer
D)
None of these
Discuss it
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.
View Solution Q.9 Where is the POST process located?
A)
ROM
B)
BIOS
C)
CPU
D)
None of these
Discuss it
Explanation
The Power-On Self-Test (POST) instructions are part of the BIOS code stored in the ROM chip.
View Solution Q.10 The BIOS is a set of?
A)
Instruction
B)
Process
C)
Execution
D)
None of these
Discuss it
Explanation
The BIOS is essentially a collection of low-level software instructions stored on a chip.
View Solution Q.11 Is the BIOS considered a 'complete' software?
A)
Yes
B)
No
C)
It may be
D)
None of these
Discuss it
Explanation
The BIOS is technically considered firmware rather than a standalone software application, as it serves as a bridge between hardware and the OS.
View Solution Q.12 Which of the following is a main function of the BIOS?
A)
POST
B)
Bootstrap Loader
C)
Drivers
D)
All of these
Discuss it
Explanation
The BIOS performs the hardware test (POST), locates/loads the OS (Bootstrap Loader), and provides low-level drivers for hardware communication.
View Solution Q.13 What is modified when changing the system start-up boot sequence?
A)
CONFIG.SYS
B)
Bootstrap Loader
C)
BIOS/CMOS
D)
None of these
Discuss it
Explanation
Changing the order of boot devices (e.g., HDD vs USB) requires modifying the settings stored in the BIOS/CMOS configuration.
View Solution Q.14 Where are BIOS drivers stored?
A)
CONFIG.SYS
B)
Bootstrap Loader
C)
ROM
D)
None of these
Discuss it
Explanation
BIOS drivers are built into the ROM chip to allow the computer to communicate with basic hardware during startup.
View Solution Q.15 What is the primary use of the BIOS?
A)
CONFIG.SYS
B)
Bootstrap Loader
C)
Operating System loading
D)
None of these
Discuss it
Explanation
The most critical role of the BIOS is to initialize the hardware and facilitate the loading of the Operating System into RAM.
View Solution Q.16 What is Firmware?
A)
Software that is part of Hardware
B)
Software stored on a flash ROM
C)
Combination of Software & Hardware
D)
All of the above
Discuss it
Explanation
Firmware is a combination of hardware and software where the code is permanently or semi-permanently programmed into a hardware device.
View Solution Q.17 What is a part of the boot startup process?
A)
Loads system files to ROM
B)
Loads system files to RAM
C)
Loads system files to HDD
D)
All of the above
Discuss it
Explanation
During startup, the BIOS instructions in ROM are used to initialize the hardware and prepare the system.
View Solution Q.18 What is an example of an extension name related to the booting process?
A)
Config.sys
B)
autoexe.bat
C)
booting.bt
D)
All of the above
Discuss it
