That is simply not true:

        Memory: power of 2    (bytes)
        Network: power of 10  (bits/s))
        Disk: power of 10     (bytes)
        CPU Frequency: power of 10 (cycles/s)
        SD/Flash/..: power of 10 (bytes)
        Bus speed: power of 10

Main memory is the odd one out.

Well some will say it's 24T :-)

You've not been misled unless you have your had in the sand for the last
five to ten years.
