BOIS Flashcards
What does BIOS stand for?
a) Basic Input/Output System
BIOS is an acronym for Basic Input/Output System, which is firmware used to perform hardware initialization during the booting process.
What is the primary function of BIOS in a computer?
b) To initialize and test hardware during booting
BIOS initializes and tests the computer’s hardware components during the boot process before handing control to the operating system.
Where is the BIOS stored?
c) On a ROM chip on the motherboard
BIOS is stored on a ROM (Read-Only Memory) chip on the motherboard, allowing it to retain its data even when the computer is powered off.
What is CMOS in relation to BIOS?
d) A chip that stores BIOS settings and system configuration
CMOS is a small chip that stores BIOS settings, such as system time, date, and hardware configuration.
What does the CMOS battery do?
c) Powers the CMOS chip to maintain BIOS settings
The CMOS battery provides power to the CMOS chip, enabling it to retain system settings even when the computer is turned off.
What happens if the CMOS battery dies?
b) The computer will lose its time and date settings
When the CMOS battery dies, the system loses its saved time, date, and BIOS settings, which must be reconfigured at each boot.
Which key is commonly used to access the BIOS setup utility during boot?
b) F2
F2, along with keys like Delete, is commonly used to access the BIOS setup utility during the computer’s boot process.
What information is typically stored in CMOS?
c) System time and date, hardware settings
CMOS stores essential system information like the time, date, and hardware configuration that the BIOS uses during startup.
What does POST stand for in relation to BIOS?
a) Power-On Self Test
POST is an acronym for Power-On Self Test, a diagnostic testing sequence that runs when the computer is powered on to ensure hardware components are working properly.
What can be changed in the BIOS settings?
b) System time and date
In BIOS, you can change various settings such as system time, date, and hardware configurations.
What is UEFI, in relation to BIOS?
b) A more advanced, modern replacement for BIOS
UEFI (Unified Extensible Firmware Interface) is a modern replacement for BIOS with more features and a user-friendly interface.
How can BIOS settings be reset to their default values?
c) By using a jumper on the motherboard or selecting “Load Defaults” in BIOS
BIOS settings can be reset by using a jumper on the motherboard or by selecting the “Load Defaults” option within the BIOS setup utility.
What is the function of the CMOS checksum error?
c) It warns that the CMOS settings may be corrupt or altered
A CMOS checksum error typically indicates that the settings in CMOS have been corrupted or altered, often due to a dying CMOS battery.
Why might a user want to update the BIOS?
d) All of the above
Updating the BIOS can improve system performance, fix hardware compatibility issues, and add support for new processors or hardware.
What is the typical voltage of a CMOS battery?
b) 3V
CMOS batteries typically have a voltage of 3 volts, which is sufficient to maintain the CMOS settings.
