The exabit is a multiple of the unit bit for digital information or computer storage. The prefix exa (symbol E) is defined in the International System of Units (SI) as a multiplier of 1018 (1 quintillion, short scale), and therefore 1 exabit = 1018 bits = 1 000 000 000 000 000 000 bits = 1000 petabits. The exabit has the unit symbol Ebit or Eb.

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