    What is BIOS' most important role?

    • A.

      Loading the operating system

    • B.

      Initiating the microprocessor

    • C.

      Running applications

    Correct Answer
    A. Loading the operating system
    Explanation
    BIOS, or Basic Input/Output System, is responsible for initializing and configuring the hardware components of a computer system. Its most important role is to load the operating system into the computer's memory during the boot-up process. This allows the operating system to take control of the computer and start running applications. Without the BIOS loading the operating system, the computer would not be able to function properly.

    Rate this question:

  • 9. 

    BIOS is type of :

      Hardware

    • B.

      Software

    • C.

      Combination of both

    Correct Answer
    C. Combination of both
    Explanation
    BIOS, or Basic Input/Output System, is a firmware that is stored on a computer's motherboard. It is responsible for initializing and controlling the hardware components during the boot process. As it is stored on a chip, it is considered a hardware component. However, it also contains software instructions that allow it to communicate with the operating system and other software applications. Therefore, BIOS can be considered a combination of both hardware and software.

    What is the first job the Basic Input Output System(BIOS) does at start-up?

    • A.

      Run memory byte count

    • B.

      Test for parity errors

    • C.

      Load instructions to RAM

    • D.

      Run the power-on-self-test

    Correct Answer
    D. Run the power-on-self-test
    Explanation
    At start-up, the BIOS performs a power-on-self-test (POST) to check the hardware components of the computer. This test ensures that the essential hardware components are functioning properly before the operating system is loaded. It checks the CPU, memory, storage devices, and other peripherals for any errors or faults. By running the POST, the BIOS can identify any potential issues and provide error codes or messages if necessary. Therefore, the first job of the BIOS at start-up is to run the power-on-self-test.

      BIOS

    • C.

      CMOS

    • D.

      EEPROM

    Correct Answer
    A. ROM
    Explanation
    ROM (Read-Only Memory) is considered as nonvolatile permanent memory because it retains its data even when the power is turned off. It contains firmware or software instructions that are permanently written during manufacturing and cannot be modified or erased by normal computer operations. ROM is used to store critical system instructions, such as the computer's startup routines, and it is not affected by power loss or system shutdowns. Therefore, ROM is the correct answer for the given question.
