• Petabytes are so 2009, Tech Briefers. Word on the street - OK, - is that there's a new measurement big enough to describe all the digital data out there - and it's called the zettabyte.

"Research published today estimates that the so-called digital universe grew by 62% last year to 800,000 petabytes - a petabyte is a million gigabytes - or 0.8 zettabytes.

The globe, combined with lightning bolt wings, signifies the Air Force's common communications heritage. The bolted wings, centered on the globe, are a design element from the Air Force Seal signifying the striking power through air, space and cyberspace. The orbits signify the space dimension of the cyberspace domain."
