    Which of the following might you find as part of a tablet computer? - ProProfs

    Which of the following might you find as part of a tablet computer?

    • Flash memory

    • SATA hard drive

    • Multi-touch touchscreen

    • 24-inch display

    Correct Answer
    A. Multi-touch touchscreen
    Explanation
    A tablet computer typically includes a multi-touch touchscreen as it allows users to interact with the device by touching the screen with multiple fingers or gestures. This feature enables various touch-based interactions such as tapping, swiping, pinching, and zooming, making it easier to navigate through applications, browse the web, and perform other tasks. Flash memory is also commonly found in tablets as it provides storage for the operating system, apps, and user data. However, a SATA hard drive and a 24-inch display are less likely to be part of a tablet computer as they are typically larger components found in desktop computers or laptops.

    How should you hold RAM when installing it? - ProProfs

    How should you hold RAM when installing it?

    • By the edges

    • By the front and back

    • With tweezers

    • With a punchdown tool

    Correct Answer
    A. By the edges
    Explanation
    When installing RAM, it is important to handle it carefully to avoid any damage. Holding it by the edges is the correct method because it minimizes the risk of touching the sensitive components on the circuit board. This helps to prevent any static electricity from being transferred to the RAM, which could potentially cause damage. By holding it securely but only by the edges, you can safely insert the RAM into the appropriate slot without risking any harm to the module.

    Which of the following might be the cause of overheating of the processor when a new CPU is being installed in a computer? - ProProfs

    Which of the following might be the cause of overheating of the processor when a new CPU is being installed in a computer?

    • The CPU is not locked down.

    • The CPU is not properly seated.

    • Thermal compound was not applied.

    • The CPU is not compatible with the motherboard.

    Correct Answer
    A. Thermal compound was not applied.
    Explanation
    When a new CPU is being installed in a computer, one possible cause of overheating could be that thermal compound was not applied. Thermal compound is a substance that helps to transfer heat from the CPU to the heat sink, ensuring efficient cooling. Without thermal compound, the heat generated by the CPU may not be dissipated properly, leading to overheating.

    Which type of port would you plug speakers into? - ProProfs

    Which type of port would you plug speakers into?

    • FireWire

    • DVI

    • USB

    • PCI-X

    Correct Answer
    A. USB
    Explanation
    USB ports are commonly used to connect external devices such as speakers to a computer. USB ports provide both power and data transfer capabilities, making them suitable for connecting speakers that require power and audio signals from the computer. FireWire is typically used for high-speed data transfer between devices such as cameras and external hard drives. DVI ports are used to connect monitors or displays. PCI-X is a type of expansion slot used for high-performance peripherals in desktop computers.

    Which process of the computer checks all your components during boot? - ProProfs

    Which process of the computer checks all your components during boot?

    • CMOS

    • POST

    • BIOS

    • EEPROM

    Correct Answer
    A. BIOS
    Explanation
    The Basic Input/Output System (BIOS) is responsible for checking all the components of a computer during the boot process. It is a firmware that is stored on a chip on the motherboard. The BIOS performs the Power-On Self-Test (POST) which checks the hardware components such as the processor, memory, storage devices, and peripherals to ensure they are functioning properly. It also initializes the hardware and loads the operating system. Therefore, the correct answer is BIOS.

  • 7. 
    Which expansion bus uses lanes to transfer data? - ProProfs

    Which expansion bus uses lanes to transfer data?

    • PCI

    • DMI

    • PCIe

    • SATA

    Correct Answer
    A. PCIe
    Explanation
    PCIe (Peripheral Component Interconnect Express) is the correct answer. PCIe uses lanes to transfer data. Lanes are individual pathways within the PCIe bus that allow for high-speed data transfer between the motherboard and peripheral devices. Each lane can transfer data independently, allowing for increased bandwidth and faster communication between components.

    Which of the following could cause the POST to fail? - ProProfs

    Which of the following could cause the POST to fail?

    • CPU

    • Power supply

    • Optical drive

    • Memory

    Correct Answer
    A. CPU
    Explanation
    The CPU (Central Processing Unit) is responsible for executing instructions and performing calculations in a computer system. If the CPU is faulty or not functioning properly, it can cause the POST (Power-On Self-Test) to fail. The POST is a diagnostic test that checks the hardware components of a computer during the boot process. If the CPU is not working correctly, it can prevent the computer from completing the POST and result in a failed boot-up.

     Which kind of socket incorporates “lands” to ensure connectivity to a CPU? - ProProfs

     Which kind of socket incorporates “lands” to ensure connectivity to a CPU?

    • PGA

    • Chipset

    • LGA

    • Copper

    Correct Answer
    A. PGA
    Explanation
    PGA stands for Pin Grid Array, which is a type of socket that incorporates "lands" or pins to ensure connectivity to a CPU. This socket design consists of an array of pins on the CPU package that align with corresponding holes on the motherboard. The pins make physical contact with the lands on the motherboard, providing a secure connection between the CPU and the motherboard.
