Answer to Question #101280 in Programming & Computer Science for lily

Question

What type of optical drive is labeled with the following number sequence 16x52x32x52x

Answer 1

These numbers describe a CD-ROM performance and define its speed of data reading. The number (16, 52 or 32) define the multiple of the original speed. For a CD the "original speed" is 150 KiB/s (1x), for a DVD the original speed 1x is 1.321 MB/s. Hence, by multiplication we can calculate the speeds. The highest speed of CD-ROMs is 72x, i.e. 10800 KiB/s.
