According to the BBC, Researchers assumed all, desde discos rígidos de computer até obsoletos disquetes e microchips de cartões de crédito.

Two zettabytes of data
"If we get all this information and store it in books, We could cover the whole area of the USA or China in three layers ", explained Martin Hilbert, the University of Southern California, the BBC. If the same information is stored digitally on CDs, the stack of disks created could reach the Moon, the researchers say.

The study results also showed that the humanity passes about 2 zettabytes of data (1 zettabyte is 1 1000 exabytes). This is equivalent to 175 newspapers per person, per day.

O armazenamento de computer tem sido tradicional medido em kilobytes, After megabytes and, now, gigabytes. Then comes terabytes, petabytes and exabytes. A exabytes equals 1 billion gigabytes.
