Wat is Zettabyte?

Chris Van Roey
zettabyte.jpg

Een zettabyte, afgekort ZB, is veelvoud van de eenheid byte. De prefix 'zetta' wijst naar een vermenigvuldiging met de zevende macht van 1000 (10007) of de eenentwintigste macht van 10 (1021) en is dus de prefix voor een triljard. In een binaire omgeving spreekt men van een zebibyte (afgekort ZIB), de zeventigste macht van 2 (270) of 1.180.591.620.717.411.303.424 bytes.
