    What does DDR stand for in DDR4 SDRAM?

    a)
    Dynamic Data Rate
    b)
    Double Data Rate
    c)
    Direct Data Ram
    d)
    Digital Data Refresh

    Explanation

    Double Data Rate RAM achieves higher bandwidth by transferring data on both the rising and falling edges of the clock signal. This effectively doubles the data transfer rate without increasing the clock frequency. Each subsequent generation (DDR2, DDR3, DDR4, DDR5) improves speed and efficiency further.
