I once worked for a company that said Ethernet switch ports were 20 Mb/s
because they are 10 Mb/s each way.
But with that oddball exception, your statement is accurate for networks. In
other domains, not so much. Fibre Channel is marketed as x Gb/s (x = 1, 2, 4,
8, 16...) but in fact x is GBaud (rounded slightly; the original rate is 1.0625
GBaud). So the real speed is 800, 1600, ... Mb/s.
By Fibre Channel standards, the original Ethernet would have been called 20
Mb/s (since it's 20 MBaud, being Manchester encoded), and Fast Ethernet would
be 125 Mb/s (since it's 125 MBaud, with 4b/5b coding) and so on. But
networking people aren't so confused (or whatever).
