    When a mouse on a surface is moved __________________________on the screen also moves. - ProProfs

    When a mouse on a surface is moved __________________________on the screen also moves.

    • Icon

    • Arrow

    • Mouse pad

    • None of these

    Correct Answer
    A. Arrow
    Explanation
    When a mouse on a surface is moved, the arrow on the screen also moves. The arrow is the graphical representation of the mouse cursor on the computer screen. As the physical mouse is moved, it sends signals to the computer, which in turn moves the arrow on the screen accordingly. This allows the user to navigate and interact with different elements and icons on the screen. The other options, such as "Icon" and "Mouse pad," do not accurately describe the direct relationship between the physical movement of the mouse and the movement of the arrow on the screen.

    A mouse is a placed in such away that the buttons should be towards the ________________

    • Monitor

    • CPU

    • Keyboard

    • All of these

    Correct Answer
    A. Monitor
    Explanation
    The correct answer is "Monitor" because typically, when using a mouse with a desktop computer setup, the mouse is placed on a flat surface near the monitor. This allows for easy access and control of the cursor on the screen. Placing the mouse towards the CPU or keyboard would not be practical or efficient for navigating the computer interface. Therefore, the buttons of the mouse should be towards the monitor.
