> Another example is network media. Serialized data transfer speed is measured in {K,M,G,T}b/s (bits) or B/s (Bytes) where a Gigabit is exactly 1000000000 bits and Gigabyte is exactly 1000000000 bytes.

interesting network trivia: a LANPHY and a WANPHY 10 gigabit ethernet connection are not quite the same thing. The latter is designed to fit within legacy DWDM transport systems designed to carry OC-192 so its data rate will fit within 9953.28 Mbit/s or slightly under that.
