    You are working for a small business as a computer tech. You notice that one of the users keeps shutting her computer down by pressing the power button instead of using the shutdown process of the operating system. You inform the user that this is not a good practice because? (choose 2 options)

    • A.

      It can cause a component failure.

    • B.

      The power surges to the components can cause damage.

    • C.

      It might take time for the power supply to recharge.

    • D.

      It could damage the monitor.

    Correct Answer(s)
    A. It can cause a component failure.
    B. The power surges to the components can cause damage.
    Explanation
    Shutting the computer down by pressing the power button is always not the proper process for switching off the system. This power-off could, over time, lead to premature component failure, and small power surges could damage components. Always shut down your system using the shutdown process unless your system hangs and there is no other option.

  • 3. 

    When determining if the problem is related to hardware or software, Which of the following is one of the most important questions to ask?

    • A.

      Is the computer plugged in?

    • B.

      What operating system are you using?

    • C.

      Have you recently installed any new hardware or software?

    If the mouse (cord-based mouse) pointer is moving intermittently on the screen but has not failed altogether, which of the following troubleshooting steps should you take?

    • A.

      Check its connection to the port.

    • B.

      Clean the mouse.

    • C.

      Reinstall the drivers.

    • D.

      Check for a conflict with the modem.

    Correct Answer
    A. Check its connection to the port.
    Explanation
    If the mouse pointer is moving intermittently, checking its connection to the port is a logical first step. A loose or faulty connection can cause intermittent issues with the mouse's functionality. Options B (Clean the mouse), C (Reinstall the drivers), and D (Check for a conflict with the modem) are also valid troubleshooting steps but are more relevant in other scenarios. Cleaning the mouse may be beneficial for general maintenance, reinstalling drivers can address software-related issues, and checking for conflicts with the modem is relevant if there are communication issues, but they might not directly address the specific symptom of an intermittently moving mouse pointer.

    • B.

      Her hard drive is corrupt.

    • C.

      She has a CMOS virus.

    • D.

      Her operating system is corrupt.

    Correct Answer
    A. A program trying to hog all the processes.

    Correct Answer(s)
    A. Defective spindle in the cd rom
    B. Defective hub lock
    C. Worn hub hole in disk
    Explanation
    The problem with the CD-ROM drive spinning very fast could be due to several reasons:
    A. Defective spindle in the CD-ROM: The spindle is the part of the CD-ROM drive that spins the disc. If it’s defective, it could cause the disc to spin too fast.
    B. Defective hub lock: The hub lock is responsible for holding the disc in place while it spins. If it’s defective, it could cause the disc to spin unevenly or too fast.
    C. Worn hub hole in disk: If the hole in the center of the disc (the hub hole) is worn, it could cause the disc to spin unevenly or too fast.
    So, options A, B, and C could be potential causes for the CD-ROM drive spinning very fast. However, it’s always a good idea to consult with a professional to diagnose the issue accurately.
