    What is used to prevent the motherboard from touching the bottom of the case when it is installed on top of stand offs?

    Explanation
    Standoffs are small metal or plastic spacers that are used to elevate and separate the motherboard from the bottom of the case. By installing the motherboard on top of standoffs, it prevents the motherboard from making direct contact with the case, which could cause electrical shorts or damage to the components. The standoffs ensure that there is enough space between the motherboard and the case, allowing for proper airflow and preventing any potential grounding issues.

    Which of the following can cause permanent damage to electrical components if you do not use proper tools and safety procedures. (choose 1 only)

    • OSHA

    • UPS

    • ESD

    • MSDS

    • Being born in Bolton

    Correct Answer
    A. ESD
    Explanation
    ESD stands for Electrostatic Discharge. It refers to the sudden flow of electricity between two electrically charged objects caused by contact, an electrical short, or dielectric breakdown. ESD can cause permanent damage to electrical components if proper tools and safety procedures are not followed. This is because the discharge can create a high voltage that exceeds the tolerance of the components, leading to their failure or degradation. Therefore, ESD is the correct answer as it highlights the potential danger and need for precautions when working with electrical components.

    Which type of ROM can only be areased with SUV light?

    • PROM

    • EPROM

    • EEPROM

    • RDROM

    • SD-DDRROM

    Correct Answer
    A. EPROM
    Explanation
    EPROM stands for Erasable Programmable Read-Only Memory. It is a type of ROM that can be erased and reprogrammed multiple times using ultraviolet (UV) light. EPROMs have a transparent quartz window on top that allows the UV light to penetrate and erase the memory contents. This makes EPROMs ideal for applications where the stored data needs to be changed or updated periodically. Unlike other types of ROMs, EPROMs require physical exposure to UV light for erasing, making them non-volatile and retaining the stored data even when power is turned off.
