The yottabit is a multiple of the unit bit for digital information or computer storage. The prefix yotta (symbol Y) is defined in the International System of Units (SI) as a multiplier of 1024 (1 septillion, short scale), and therefore 1 yottabit = 1024 bits = 1 000 000 000 000 000 000 000 000 bits = 1000 zettabits. The yottabit has the unit symbol Ybit or Yb.
The zebibit is a multiple of the bit, a unit of digital information storage, prefixed by the standards-based multiplier zebi (symbol Zi), a binary prefix meaning 270. The unit symbol of the zebibit is Zibit. 1 zebibit = 270 bits = 1 180 591 620 717 411 303 424 bits = 1024 exbibits.
