1 GHz = 1000 MHz = 1,000,000 KHz = 1,000,000,000 Hz

Ahh, but much too often there is
a confusion - if you buy a computer
that is quoted as having 1Gb of
memory, you aren't likely to receive
exactly 1,000,000,000 bytes ;-)

There may be confusion about the meaning og Giga-, Mega-, and Kilo-
when it comes to memory space, just because 1024 is a handy integer
power of 2 -- but there is no such confusion when it comes to _frequency_,
which is what the original poster was talking about.

Well, you'll at least get 1,000,000,000*8 bits. The problem was that
IT handled prefixes as powers of 2. So the kb were 1024*8 bits,
the MB were 2^20*8 bits and so on.
That is why you've ment 1Gb=2^30*8 bits. AFAIK they changed the
international convention from KB,MB,GB... to KiB, MiB, GiB so that now
the old k/M/G are exactly in SI-style (1000/1000000/1000000000) and
Ki/Mi/Gi stand for the IT-version (powers of 2: 1024/2^20/2^30).

Sorry to answer to this one specific mail out of a rather
large number that I received on the subject (it just
happened to be the last I saw).
Believe me, I do know the difference between 2 and 10
based definitions of of Kilo, Mega, Giga, Tera and so on.
It was just meant to show why the question has arised in
the first place. I wonder why not one of the respondents
noticed the smiley at the end of what I wrote?
