Actually a 1 Mb/s connection is 1024000 bits/second (ie not 1000000 or 1048576 bits/second).
This came about because a basic voice channel is 64kb/s = 64000 bits/second. These are aggregated up into 32 channels at a time which is known as an E1 in Europe. An E1 is known as a 2 "meg" connection though it is 2048000 bits/s. Perhaps the correct appellation is 2 kkib/s?
Poor confused telecoms engineers ;-)
My personal view is that the kiB MiB GiB etc are very ugly but we should grin and bear it to banish this decimal binary confusion forever. Either that or put a note somewhere saying that all k, M and G are 2^10, 2^20 and 2^30 and forget about it for a generation...
