Subject: Re: One Peta Byte = <some useless trivia>

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
Yottabyte .... 10 to the 24th power
Googolbyte ... 10 to the 100th 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!
