Question: 1 / 525

The PC-1600 RAM specification corresponds to which DDR standard?

DDR-100

DDR-200

The PC-1600 RAM specification corresponds to the DDR-200 standard. This designation is based on the actual data transfer rate that the memory can support. In DDR (Double Data Rate) terminology, the "PC" notation signifies the peak bandwidth or data rate that the RAM can facilitate. Specifically, PC-1600 indicates that the memory module can handle a theoretical maximum bandwidth of 1.6 GB/s.

To align this with DDR specifications, you take the bandwidth number (1.6 GB/s) and divide it by 8 (to convert from bytes per second to bits per second), which yields a data rate of 200 MT/s (Mega transfers per second). This matches the characteristics defined by the DDR-200 standard, making it the correct answer.
