Yottabit
Encyclopedia
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
The yottabit has the unit symbol Ybit or Yb.
The yottabit is closely related to the yobibit
, a unit multiple derived from the binary prefix
yobi of the same order of magnitude, which is equal to = , or approximately 21% larger than the yottabit.
