Questions and Answers
  • 1. 

    The computer uses the .......... number system to store data and perform calculations.

    • A.

      Binary

    • B.

      Octal

    • C.

      Decimal

    • D.

      Hexadecimal

    • E.

      None of these

    Correct Answer
    A. Binary
    Explanation
    The computer uses the binary number system to store data and perform calculations. In the binary system, numbers are represented using only two digits, 0 and 1. This is because computers use electronic circuits that can only represent two states, on and off. Each digit in a binary number is called a bit, and a group of 8 bits is called a byte. The binary system is fundamental to computer architecture and is used to encode and process all types of data, including text, images, and instructions.

    The simultaneous processing of two or more programs by multiple processors is:

    • A.

      Multiprogramming

    • B.

      Multitasking

    • C.

      Time-sharing

    • D.

    Explanation
    Multiprocessing refers to the simultaneous execution of multiple programs by multiple processors. This allows for improved performance and efficiency as tasks can be divided among different processors, enabling them to work on different programs simultaneously. Unlike multitasking, which involves switching between tasks on a single processor, multiprocessing utilizes multiple processors to execute multiple programs concurrently. Time-sharing refers to the sharing of computing resources among multiple users, and multiprogramming refers to the ability of a computer to execute multiple programs concurrently, but not necessarily on multiple processors. Therefore, the correct answer is multiprocessing.

    When a computer is switched on, the booting process performs

    • A.

      Integrity Test

    • B.

      Power-On Self-Test

    • C.

      Correct Functioning Test

    • D.

      Reliability Test

    • E.

      Shut-down

    Correct Answer
    B. Power-On Self-Test
    Explanation
    When a computer is switched on, the booting process performs a Power-On Self-Test (POST). This test is designed to check the hardware components of the computer for any issues or failures. It ensures that the essential components such as the processor, memory, and input/output devices are functioning correctly. The POST is an important step in the booting process as it helps to identify and diagnose any hardware problems before the operating system is loaded.

    Which of the following does not store data permanently?

    • A.

      ROM

    • B.

      RAM

    • C.

      Floppy Disk

    • D.

      Hard Disk

    • E.

      None of these

    Correct Answer
    B. RAM
    Explanation
    RAM (Random Access Memory) does not store data permanently. It is a type of computer memory that is volatile, meaning it loses its data when the power is turned off or interrupted. RAM is used for temporary storage of data that is actively being used by the computer's processor. Once the power is turned off, the data stored in RAM is erased. In contrast, ROM (Read-Only Memory), floppy disks, and hard disks are all non-volatile storage devices that can retain data even when the power is off.

      Gigabyte

    • C.

      Kilobyte

    • D.

      Terabyte

    • E.

      Nanobyte

    Correct Answer
    E. Nanobyte
    Explanation
    A nanobyte is the smallest unit of storage among the options given. While a kilobyte is 1,000 times larger than a byte, a megabyte is 1,000 times larger than a kilobyte, and a gigabyte is 1,000 times larger than a megabyte, a terabyte is 1,000 times larger than a gigabyte. In comparison, a nanobyte is even smaller than a byte, representing a fraction of a byte. Therefore, the nanobyte is the smallest storage unit among the given options.
