    Which of the following sleep modes is the most power hungry mode?

    • S1

    • S2

    • S0

    • S3

    Correct Answer
    A. S1
    Explanation
    S1 sleep mode is the most power hungry mode among the given options. In S1 sleep mode, also known as "Standby" or "Suspend to RAM," the computer enters a low-power state where the CPU and other components are powered down, but the RAM remains active. This allows for a quick wake-up time as the system can resume from where it left off. However, since the RAM still requires power to maintain its data, S1 mode consumes more power compared to other sleep modes like S2, S0, or S3.

    Andrew has a personal computer. One morning, he starts his computer and hinds the following error message: "CMOS checksum failure. "What are the most likely causes of this error? Choose two

    • BIOS has become outdated.

    • The CMOS battery has failed.

    • The CMOS chip has failed

    • Software stored in the CMOS battery is infected by a virus.

    Correct Answer(s)
    A. The CMOS battery has failed.
    A. The CMOS chip has failed
    Explanation
    The error message "CMOS checksum failure" indicates that there is an issue with the CMOS (Complementary Metal-Oxide-Semiconductor) settings in Andrew's computer. The CMOS battery is responsible for maintaining these settings, so if it has failed, it can cause this error. Additionally, if the CMOS chip itself has failed, it can also result in a checksum failure. Therefore, the most likely causes of this error are a failed CMOS battery and a failed CMOS chip.

    Which of the following can occur if the power cable runs along with the computer network cable?

    • EMI

    • ESD

    • Broadcast Storm

    • Surge

    Correct Answer
    A. EMI
    Explanation
    If the power cable runs along with the computer network cable, it can lead to Electromagnetic Interference (EMI). EMI occurs when the electrical signals from the power cable interfere with the signals from the network cable, causing distortion or disruption in the network communication. This can result in poor network performance, data errors, or even complete network failure. It is important to keep power cables and network cables separated to minimize the risk of EMI.

    Which of the following are types of LCD monitors? Choose two

    • SVGA

    • Active Matrix

    • Passive Matrix

    • X-Matrix

    Correct Answer(s)
    A. Active Matrix
    A. Passive Matrix
    Explanation
    Active Matrix and Passive Matrix are both types of LCD monitors. Active Matrix refers to a type of display technology that uses thin film transistors (TFTs) to control each individual pixel on the screen, resulting in faster response times and better image quality. Passive Matrix, on the other hand, uses a grid of electrodes to control the pixels, which is less expensive but can lead to slower response times and lower image quality compared to Active Matrix. X-Matrix is not a recognized type of LCD monitor. SVGA refers to a resolution standard and is not specifically a type of LCD monitor.
