Indoklás? Mert egy vizsgán ilyesmiért simán kivágnak.
"Computer clock frequencies are always quoted using SI prefixes in their decimal sense. For example, the internal clock frequency of the original IBM PC was 4.77 MHz, that is, 4770000 Hz.
"When quantifying large bit rates, SI prefixes (also known as Metric prefixes or Decimal prefixes) are used, thus:
1,000 bit/s rate = 1 kbit/s (one kilobit or one thousand bits per second)
1,000,000 bit/s rate = 1 Mbit/s (one megabit or one million bits per second)
1,000,000,000 bit/s rate = 1 Gbit/s (one gigabit or one billion bits per second)
Binary prefixes have almost never been used for bitrates, although they may occasionally be seen when data rates are expressed in bytes per second (e.g. 1 kByte/s or kBps is sometimes interpreted as 1000 Byte/s, sometimes as 1024 Byte/s)."

Vagy vegyük például a Shannon-Hartley tételt, ahol tisztán látszik az adatátviteli sebesség és a sávszélesség kapcsolata.
