8 bits = 1 Byte
What comes after the Byte ?
1024 Bytes = 1 Kilobyte
What comes after the kilobyte ?
1024 Kilobytes = 1 Megabyte
What comes after the Megabyte ?
1024 Megabytes = 1 Gigabyte
What comes after the Gigabytes ?
1024 Gigabytes = 1 Terabyte
What comes after the Terabytes?
1024 Terabytes = 1 Petabyte
What comes after the Petabytes ?
1024 Petabytes = 1 Exabyte
What comes after the Exabyte ?
1024 Exabyte = 1 zettabyte
What comes after the zettabyte ?
1024 zettabyte = 1 Yottabyte

That is wrong, but common. 1KByte is 1,000 Bytes; etc.

Yes.

No, but that's a common mistake. 1024k is 1 mebibyte, where the 'bi'
indicates use of binary math. Likewise on upward for gebi, tebi, pebi, exbi
and, presumably, yebi and zebi.

You are incorrect. 1KByte has always been about 1024 bytes. Now, the
larger disk drives have gotten, the more they want to use base 10
calculations where 1MB = 1,000,000 bytes. Yes, this is problematic as some
(most?) operating systems still use mulitples of 1024 for megabyte
calculations. THAT is 'incorrect' but it's a legacy annoyance, as is the
historical usage of kilobyte = 1024.

If only life were so simple. See:
<http://en.wikipedia.org/wiki/Byte>
<http://en.wikipedia.org/wiki/SI_prefix>
and from the NIST, we have:
<http://physics.nist.gov/cuu/Units/binary.html>
<http://physics.nist.gov/cuu/Units/prefixes.html>
Of course, standards are made to be broken:
<http://en.wikipedia.org/wiki/Non-SI_unit_prefix>
For entertainment value, try using these:
2 bits: crumb, quad, quarter, tayste, tydbit
4 bits: nibble, nybble
5 bits: nickle, nyckle
10 bits: deckle
16 bits: plate, playte, chomp, chawmp (on a 32-bit machine)
18 bits: chomp, chawmp (on a 36-bit machine)
32 bits: dinner, dynner, gawble (on a 32-bit machine)
48 bits: gobble, gawble (under circumstances that remain obscure)
I once proposed the pseudobyte as equal to 1012 bytes. That's the
arithmetic average of 1000 bits and 1024 bits, which should serve as a
suitable compromise value thus satisfying both camps. It was
summarily rejected as counterproductive by all that took me seriously.
It also gets ugly with speed abreviations, such as Bps, bps,
Bytes/sec, bits/sec, etc. I won't go there and simply suggest that
one should not abrev.
Try not to byte off more than you can chew.

This statement is also wrong, but common.
In fact /both/ are correct.

Yeah, we all know what the ISO standard is, and hands up any /real/
human that uses kibi, mibi etc.

This is a modern invention, written by the committee that invented the
camel, in order to 'deobfuscate' something that wasn't actually
complicated in the first place.

Ok, I'll byte. What comes next?

I did, once, and only once. It was in a performance test report,
where the use was appropriate. However, nobody could figure out what
I was talking about or knew what a mibibyte was, so I revised it back
to the common usage, tweaked the numbers, and never made that mistake
again.

Ummm... It's kebi (KiB), mebi (Mib), etc.
As usual, the abrevs make no sense and are guaranteed to confuse.

After you byte, you chew. Following that, you swallow. The rest of
the description is unsuitable for a family newsgroup.

Bob, you must work for Seagate.

fundamentalism, fundamentally wrong.
