    Which of the following devices might be found on the front or back of a computer? (Choose all correct answers.)

    • Activity lights Power switch USB ports None Activity lights

    • Power switch

    • USB ports

    • None of these options are correct

    Correct Answer(s)
    A. Activity lights Power switch USB ports None Activity lights
    A. Power switch
    A. USB ports
    Explanation
    Activity lights, power switch, and USB ports are all devices that can be found on the front or back of a computer. Activity lights are used to indicate the status of various components such as the hard drive or network connection. The power switch is used to turn the computer on or off. USB ports are used to connect external devices such as keyboards, mice, or flash drives to the computer. Therefore, all of these options are correct.

    You are working on a computer. Which of the following are considered essential? (Choose all correct answers.)

    • Motherboard

    • CPU

    • Memory

    • Video card

    • A scanner

    Correct Answer(s)
    A. Motherboard
    A. CPU
    A. Memory
    A. Video card
    Explanation
    The motherboard, CPU, memory, and video card are considered essential components of a computer. The motherboard serves as the main circuit board that connects all the other components together. The CPU (Central Processing Unit) is the brain of the computer, responsible for executing instructions and performing calculations. Memory, also known as RAM (Random Access Memory), is used to temporarily store data and instructions that the CPU needs to access quickly. The video card, or graphics card, is responsible for rendering and displaying images and videos on the computer's monitor. A scanner, on the other hand, is not an essential component as it is an external device used for inputting physical documents or images into the computer.

    What is the process of bypassing the CPU called?

    • Direct Memory Access

    • Memory Leak

    • Task Manager

    • Device Manager

    Correct Answer
    A. Direct Memory Access
    Explanation
    Direct Memory Access (DMA) is the process of bypassing the CPU and allowing external devices to directly access the system's memory. This enables faster data transfer between the device and the memory without involving the CPU in every data transfer. DMA is commonly used in devices like sound cards, network cards, and hard drives to improve performance and reduce CPU overhead.

    How do you attach the VGA cable to the video card to prevent it from losing connection?                       

    • By snapping it into the video port with both thumbs

    • By using the locking arm mechanism

    • By using a torx screwdriver

    • By turning the thumbscrews

    Correct Answer
    A. By turning the thumbscrews
    Explanation
    To prevent the VGA cable from losing connection, you should attach it to the video card by turning the thumbscrews. Thumbscrews are designed to secure the cable firmly in place, providing a stable connection. By turning the thumbscrews, you can tighten the cable and ensure that it stays securely attached to the video port, minimizing the risk of disconnection.

    Which of the following are the most commonly used Windows operating systems? (Choose the three best answers.)

    • Windows XP

    • Windows 2000

    • Windows Vista

    • Windows 98

    Correct Answer(s)
    A. Windows XP
    A. Windows 2000
    A. Windows Vista
    Explanation
    Windows XP, Windows 2000, and Windows Vista are the most commonly used Windows operating systems. These three versions of Windows have been widely adopted and used by individuals and businesses alike. Windows XP was particularly popular and widely used for a long time until its support ended in 2014. Windows 2000 was also widely used, especially in business environments. Windows Vista, although not as popular as XP, was still commonly used before the release of Windows 7.

    How do you identify the cable that connects to the floppy drive?

    • It is flat.

    • It is the longest cable.

    • There is a twist at one end.

    • None of these options are correct.

    Correct Answer
    A. There is a twist at one end.
    Explanation
    The correct answer is "There is a twist at one end." This is because floppy drive cables typically have a twist in the cable near one end. This twist is used to indicate which end of the cable should be connected to the floppy drive. The twist helps ensure that the cable is properly aligned and connected to the correct pins on the drive.

     Which of the following can help in preventing ESD? (Choose two.)

    • Touch the unpainted metal of the chassis

    • Wear sneakers

    • Remove the power supply

    • Wear an antistatic wrist strap

    Correct Answer(s)
    A. Touch the unpainted metal of the chassis
    A. Wear an antistatic wrist strap
    Explanation
    Touching the unpainted metal of the chassis helps in preventing ESD because it allows the person to discharge any static electricity they may have built up before touching sensitive electronic components. Wearing an antistatic wrist strap also helps in preventing ESD as it grounds the person and prevents the buildup of static electricity.

    Which of the following can be used in your day-to-day work on a standard Windows computer? (Choose the two best answers.)

    • CHKDSK

    • Toopath

    • Disk Defragmenter

    • Ifconfig

    Correct Answer(s)
    A. CHKDSK
    A. Disk Defragmenter
    Explanation
    CHKDSK and Disk Defragmenter are the two best answers because they are both utilities that can be used on a standard Windows computer for regular maintenance and optimization. CHKDSK (Check Disk) is used to scan and fix errors on the hard drive, while Disk Defragmenter is used to reorganize fragmented files on the hard drive, improving overall system performance.

    Which of the following steps is important to perform when opening the case to access the internal parts of a computer?

    • Check your system manual

    • Get out the screwdriver

    • Check your system manual Get out the screwdriver Check for ESD

    • None of these options are correct

    Correct Answer
    A. Check your system manual
    Explanation
    When opening the case to access the internal parts of a computer, it is important to check the system manual. This is because the manual provides specific instructions and guidelines for safely opening the case and accessing the internal components. It may also provide information on any special precautions that need to be taken or specific steps that need to be followed. By checking the system manual, the user can ensure that they are properly informed and can avoid any potential damage or problems when accessing the internal parts of the computer.

    Which of the following can cause a desktop computer to fail? (Choose all that apply.)

    • Overheating

    • Loose add-on cards

    • Drive failures

    • Adding more memory

    Correct Answer(s)
    A. Overheating
    A. Loose add-on cards
    A. Drive failures
    A. Adding more memory
    Explanation
    Overheating can cause a desktop computer to fail because excessive heat can damage the internal components and lead to system shutdowns or permanent damage. Loose add-on cards can also cause failure as they may become dislodged or cause connectivity issues, resulting in system instability or failure. Drive failures can cause a computer to fail as it may result in data loss or the inability to access important files. Adding more memory, however, does not typically cause a desktop computer to fail as long as it is compatible and properly installed.

    Rate this question:

  • 12. 

    Which of the following types of hardware resources do both onboard and addon card devices use? (Choose all that apply.)

    • IRQ

    • DMA

    • Memory

    • I/O port

    Correct Answer(s)
    A. IRQ
    A. DMA
    A. Memory
    A. I/O port
    Explanation
    Onboard and addon card devices both use IRQ, DMA, Memory, and I/O port as types of hardware resources. IRQ (Interrupt Request) is used to handle hardware interrupts, DMA (Direct Memory Access) allows devices to transfer data directly to and from memory without involving the CPU, Memory is used for storing data and instructions, and I/O port is used for communication between devices and the CPU.
