The zettabit is a multiple of the unit bit for digital information or computer storage. The prefix zetta (symbol Z) is defined in the International System of Units (SI) as a multiplier of 1021 (1 sextillion, short scale),[1]and therefore 1 zettabit = 1021 bits = 1 000 000 000 000 000 000 000 bits = 1000 exabits. The zettabit has the unit symbol Zbit or Zb.

In computing, a nibble (often nybble or nyble to match the spelling of byte) is a four-bit aggregation, or half an octet.
