**Kibibit** (Kib, Kibit) - 1024 bits (= 128 bytes).

The

SI (International System of Units) defines the prefix "kilo-" to be exactly 1 000. In computer usage this is usually approximated with 1 024 (2^10).

All goes well, until storage gets into Gigabyte magnitudes. You see, 2^30 is 1 073 741 824, which is 7% more than 1 billion. So someone came up with the idea to make a new set of prefixes for powers of two.

But not everyone is adopting these prefixes. When you see GB on a hard drive, it's 1 000 000 000 bytes (a billion bytes), but when you see it on your computer it's usually 1 073 741 824 bytes. Except GNOME, which uses Gibibytes.

Also the nickname of a chatter of #twokinds.

**Bit** Short for "binary digit", is the lowest unit of data in current electronic computers. Takyoji is wrong here. Abbreviated sometimes

**b**.

*Okay, I didn't see the post time, I usually don't look at them... but still... it's been like that for 3 years?*
**Nibble** - Half a byte (4 bits), not 1/5 - 1/8 bytes.

**Byte** - also called an

**octet**, this is 8 bits, save for some old IBM mainframes that have 9-bit bytes. Abbreviates sometimes

**B**, which also means Bel, but Bel is mostly used in decibel (dB) so....

**Kilobit** - 1000 bits. Abbreviated kb.

**Kibibit** - see above.

**Kilobyte** - Exactly 1 000 bytes, or equal to 1 Kibibyte. Abbreviated

**kB**. Notice the capitalization.

**Kibibyte** (Kib, Kibit) - 1,024 bytes.

**Megabit** (Mb) - 1 000 000 bits.

**Mebibit** (Mib, Mibit) - 1 048 576 bits, or 131 072 bytes.

**Megabyte** (MB) - 1 000 000 bytes, or equal to 1 Mebibyte.

**Mebibyte** (MiB) - 1 048 576 bytes. 1024 times larger than a Kibibyte.

**Gigabit** (Gb) - 1 000 000 000 bits.

**Gibibit** (Gib, Gibit) - 1 073 741 824 bits, or 134 217 728 bytes.

**Gigabyte** (GB) - 1 000 000 000 bytes, or equal to 1 Gibibyte.

**Gibibyte** (GiB) - 1 073 741 824 bytes. 1024 times larger than a Mebibyte.

And so we have a slew of units, each 1000 or 1024 times larger than the one before, Terabyte/Tebibyte, Petabyte/Pebibyte, Exabyte/Exbibyte, Zettabyte/Zebibyte and...

Yes, there still are units larger than Zebibyte!

**Yottabit** (Yb) - 1 000 000 000 000 000 000 000 000 bits.

**Yobibit** (Yib, Yibit) - 1 208 925 819 614 629 174 706 176 bits, or 151 115 727 451 828 646 838 272 bytes.

**Yottabyte** (YB) - 1 000 000 000 000 000 000 000 000 bytes, or equal to 1 Yobibyte.

**Yobibyte** (YiB) - 1 208 925 819 614 629 174 706 176 bytes. 1024 times larger than a Zebibyte. As you can see, it's 20% larger than a Yottabyte...

**digitalizer** - Another name for graphics tablet, as it takes real-world positions and turns them into digits.

**dB** (

Decibel) - A unit for ratio between two values in logarithmic, commonly used in electrical engineering, to describe sound volume and pressure... Umm, can I point to
