Department of BIG, Scary Numbers

The now familiar TERABYTE is 1,024 gigabytes, equivalent to all the X-ray films in a large technological hospital; the increasingly common PETABYTE is 1,024 terabytes – that’s a quadrillion bytes, equal to about half of all U.S. academic research libraries. Info inflation brings us to the EXABYTE, equal to 1,024 petabytes or half the total volume of information generated worldwide annually.

Be prepared for more, with a ZETTABYTE standing for 1,024 exabytes, and a YOTTABYTE for 1,024 zettabytes.
