- Well, "1K == 2**10" certainly doesn't carry over into the area of
- digital communications. A 9600 bps channel is commonly abbreviated
- "9.6K," and 1.544Mb/s has never meant anything but 1.544x10**6.
-
- About the only place that the 1024 base is firmly entrenched is in the
- area of computer memory, which, in a world of binary signals, is pretty
- solidly locked into powers of 2. Disks and tapes lie in a grey area.
- Marketing being what it is, that means that base 10 will win out.
-
- Actually, I once saw a computer advertised as having "4.2 Meg" of
- memory, but only once.
