    Correct Answer
    B. Damage to the operating system (Windows) from a computer virus causes most Windows errors.
    Explanation
    Damage to the operating system (Windows) from a computer virus causes most Windows errors. This is because computer viruses can corrupt or modify important system files, leading to instability and errors in the operating system. When these files are damaged, it can result in a Blue Screen of Death (BSOD) error, which indicates a critical system failure. Therefore, the presence of a computer virus is the most likely cause of Windows errors on a typical home computer.

    Using a shorter cord can help fix many problems with USB devices because longer cords can cause signal degradation and power loss. By using a shorter cord, the device can receive a stronger and more stable signal, resulting in better performance and fewer issues.

    Rate this question:

  • 6. 

    What is the name of the system built into most hard drives that predict how long until they’ll fail?

    • A.

      Power-On Self-Theck (POST) can warn you when a device will fail.

    • B.

      Redundant Array (of) Independent Disks (RAID) can warn you when a device will fail

    • C.

      Self-Monitoring And Reporting Technology (SMART) can warn you when a device will fail.

    • D.

      Microsoft Chkdsk can warn you when a device will fail.

    Correct Answer
    C. Self-Monitoring And Reporting Technology (SMART) can warn you when a device will fail.
    Explanation
    SMART (Self-Monitoring And Reporting Technology) is a system built into most hard drives that monitors various parameters such as temperature, error rates, and bad sectors. It predicts the likelihood of drive failure and provides warnings to the user, allowing them to take necessary actions such as backing up data and replacing the drive before it fails. POST, RAID, and Microsoft Chkdsk do not have the capability to predict hard drive failure.

  • 7. 

    What is usually the easiest way to fix an application that won’t start anymore?

    • A.

      Run your virus scanner to fix the application because you probably have a virus.

    • B.

      Reboot your computer to fix the application because it’s probably a system error.

    • C.

      Uninstall and reinstall the application to reset the application completely.

    • D.

      Run Windows Registry repair software to fix the application because it’s probably a registry error.

    Correct Answer
    B. Reboot your computer to fix the application because it’s probably a system error.
    Explanation
    Often, a simple reboot of the computer can resolve issues with applications that won't start. This is because a reboot can help clear temporary system glitches or conflicts that may be preventing the application from launching.

    Option C (Uninstall and reinstall the application) is also a valid troubleshooting step. If the application's files or settings have become corrupted, reinstalling it can provide a fresh start.

    Options A and D are generally not recommended as first-line solutions. Running a virus scanner (Option A) is essential for security but may not directly fix an application launch issue. Similarly, using registry repair software (Option D) can be risky and is typically unnecessary for resolving most application startup problems.

      You should check your Windows Updates for any patches you need to install.

    Correct Answer
    C. You should check your computer memory (RAM) in case it’s starting to fail.
    Explanation
    If you are experiencing strange errors on your computer and have ruled out the possibility of a virus, checking your computer memory (RAM) is the next logical step. RAM is responsible for temporarily storing data that is actively being used by your computer. If the RAM starts to fail, it can cause various issues such as system crashes, freezing, or random errors. By checking the RAM, you can determine if it is the cause of the strange errors and take appropriate steps to resolve the issue.
