All of which is not as big a deal today with these huge drives. When we had
only 'MBs', and not many of them it was a much bigger issue because whatever
we could get onto a 20-40mb drive we would.....:-)

Hehe. Yes. But it's still just as confusing to the uninitiated.

I think you mean "pseudo" binary, since you are the only person who
ever calls it that.

I call it pseudo binary because it isn't binary.

Binary looks like this... 10001001101
Decimal looks like this... 1093.456

In scientific notation, 4.5G is 4.5x10^9 or 4,500,000,000. You could also
write it as 4,500M, or 4,500x10^6. That's because each position is a power
of 10, which is why it's called 'deci'mal.

In binary, each position is a power of 2, which is why it's called 'bi'nary.

4.5G in 'computerese' pseudo binary is the hack of a decimal number times a
a binary power. I.E. 4.5 x 2^30 or 4.5 times 1073741824 = 4831838208 (in
decimal representation)

What happens if you try to write 4.5G 'computerese' pseudo binary as
4,500M? You get 4,500x2^20 or 4,500x1048576 = 4718592000 (in decimal
representation).

Notice how they aren't the same? That's because the 4.5 and 4,500 are
decimal numbers hacked into the front of a binary and they don't 'mix'.

Put another way, .5Gig <> 500Meg in 'computerese' pseudo binary because the
front number, being decimal, is multiplied by 10s and the ass end, being a
binary, is multiplied by powers of 2, and there is no integral power of 2
that equals 10.

A decimal front with a binary ass, made even worse by using a decimal
prefix to denote powers of 2, isn't "binary" nor, for that matter, is it
decimal.

The proper binary prefixes, and the abbrviations, are:

kibibyte, KiB
mebibyte, MiB
gibibyte, GiB
tebibyte, TiB
pebibyte, PiB
exbibyte, EiB
zebibyte, ZiB
yobibyte, YiB

kibi, sure
mebi, maybe
gigi, yeah she's fine... :`)
tebi and pebi.. yawn!
don't know about exbi and zebi though
and who the heck is yobi?

Sorry, I am not so serious today...
Nice explanation :)

regards,
Marcel
