Because the prefixes kilo, mega, giga, etc. translate as 1,000 1,000,000, and 1,000,000,000, but a kilobyte is 1024 bytes a megabyte is 1024 * 1024 bytes and and gigabyte is 1024 * 1024 * 1024 bytes, new prefixes are being proposed. The prefixes are kibi, mebi, gibi. tebi, etc. The "bi" stands for binary.
Also Oracle's claim to support 512 petabytes, errrr... pebibytes, is theoretical until they begin supporting HPSS or some other hierarchical file system which provides for near line storage.

Byte Measured terms (roughly):
Megabyte ..... 10 to the 6th power Gigabyte ..... 10 to the 9th power (or 1024 Megabytes) Terabyte ..... 10 to the 12th power (or 1024 Gigabytes) Petabyte ..... 10 to the 15th power (or 1024 Terabytes) Exabyte ...... 10 to the 18th power (or 1024 Petabytes) Zettabyte .... 10 to the 21st power
Example: a GB (Gigabyte) is one thousand million byrtes - one million bytes. More precisely: 1,073,741,824 bytes.
I am NOT making this up! These are terms to specify data transmission rates... I just hope I do not have to manage a "Googolbyte" database during my lifetime!
