Hi,
What do you know about "k" meaning "*1000" and "K" meaning"*1024?" That is
the notation I got used to.
Yes, I think the idea of using "1000" instead of "1024" comes for ease of
understanding and describing some terms of memory in digital domain.

OMG I'm surprised about you Gman! You forgot the "K = Kilo or Thousand
of...". And although "b" (bits) is rarely used for storage capacity (like
hard drives, memory, etc), it is used very often for measuring speed or
throughput (like internet speed). Hmm, ok, I'll give you that one since the
original request was talking about storage space.
You're probably gonna kill me for bringing up the fact that this whole
system gets convoluted by the fact that a "K" (or Thousand) is usually (but
not always) actually 1,024 instead of 1,000. Ok, you probably left this out
because it turns easy to understand terms (like Million, Billion, Trillion)
into a confusing issue (one thousand and what?), but I'm bringing it up now
to answer the question of "Why does my 500 GB hard drive show that it only
has 465 GB when it is empty?". Well, its because hard drive manufacturers
measure a KB = 1,000 while Windows and pretty much everything else that is
computer related uses KB = 1,024. I don't know of anyone that knows for
sure why the hard drive industry uses 1,000.

Lots of confusion surrounds these terms, so I'm really glad you asked.
b = bit which is a single 1 or 0
B = byte which is 8 bits. It takes 8 bits to represent a single character
such as 5 or Y.
M = Mega or 1 Million of ...
G = Giga or 1 Billion of ... I have two 500GB hard drives I use solely for
storage.
T = Tera or 1 Trillion of ... There are now hard drives on the market that
can hold 1TB or more of data.
So, a MB = a MegaByte which means 1 million bytes worth of data. A floppy
disk can hold up to 1.38MB of data. A typical CD holds up to 700MB and a
DVD can store about 4,700MB or 4.7GB. You will probably NEVER hear anything
described in Mb (MegaBit) format. That format is basically used only by
engineering majors.
Yes, a 990MB movie will fit comfortably on a single 4.7GB DVD disc You
could fit 4 movies of that size on there if you really wanted to. :)
Peace,
Gman
