It depends on what you are talking about.
Ken Puls has given one correct answer - when referring to amounts of memory
(RAM) and when Windows XP to get drive sizes and space available, it is just
as he has said.
1024 = 1 kilobyte
1024 x 1024 = 1 megabyte
1024 x 1024 x 1024 = 1 gigabyte

But some devices are measured differently for marketing purposes. Hard disk
drives are a good example of that. A 1 Gigabyte hard drive (if you could
find one that small) would only have 1,000,000,000 (1000 x 1000 x 1000) bytes
of storage available on it. So when you got your drive home and installed
it, you would find that Windows would report it as a .93 GB drive.

For more real-world numbers, consider these:
I have a 250 GB (advertised size) drive that shows up as 220 GB in Windows
I have a 500 GB (advertised size) drive that shows up as 465 GB in Windows
