A zettabyte (derived from the SI prefix zetta-) is a unit of information or computer storage equal to one sextillion (one long scale trilliard) bytes. It is commonly abbreviated ZB. At this time, no computer has one zettabyte of storage. When used with byte multiples, the SI prefix may indicate a power of either 1000 or 1024, so the exact number may be either: In computer science a byte (pronounced bite) is a unit of measurement of information storage, most often consisting of eight bits. ...
