    Which type of memory transfers data twice as fast as SDRAM and increases performance by transferring data twice per cycle?

    • DDR-SDRAM

    • DRAM2

    • D-SDRAM

    • ROM

    Correct Answer
    A. DDR-SDRAM
    Explanation
    DDR-SDRAM stands for Double Data Rate Synchronous Dynamic Random Access Memory. It is a type of memory that transfers data twice as fast as SDRAM (Synchronous Dynamic Random Access Memory). DDR-SDRAM increases performance by transferring data twice per cycle, which means it can transfer data on both the rising and falling edges of the clock signal. This allows for higher data transfer rates and improved overall system performance.

    What is the maximum data speed of high-speed USB 2.0?

    • 1.5 Mbps

    • 12 Mbps

    • 380 Mbps

    • 480 Mbps

    • 480 Gbps

    • 840 Gbps

    Correct Answer
    A. 480 Mbps
    Explanation
    The maximum data speed of high-speed USB 2.0 is 480 Mbps. This is the correct answer because USB 2.0 is capable of transferring data at a maximum rate of 480 megabits per second.

    How many universal serial bus (USB) devices can be connected to a USB port?

    • 256

    • 127

    • 64

    • 128

    Correct Answer
    A. 127
    Explanation
    A USB port can support up to 127 USB devices. This is because USB technology uses a 7-bit address field, allowing for a maximum of 127 unique addresses. Each USB device connected to the port is assigned a unique address, and the port can handle communication with all of these devices simultaneously. Therefore, the correct answer is 127.

    Which type of video connector has a 24-pin or 29-pin female connector and provides compressed digital output to a monitor?

    • AAV

    • DVI

    • HDMI

    • RCA

    • VGA

    Correct Answer
    A. DVI
    Explanation
    DVI stands for Digital Visual Interface and is a video connector that has a 24-pin or 29-pin female connector. It provides compressed digital output to a monitor, making it a suitable choice for transmitting high-quality video signals. DVI cables are commonly used to connect computers to monitors or projectors, ensuring a clear and sharp display.
