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.

The terabyte is a multiple of the unit byte for digital information. The prefix tera represents the fourth power of 1000, and means 1012 in the International System of Units (SI), and therefore one terabyte is one trillion (short scale) bytes, 1000 gigabytes, 1000 000 megabytes. The unit symbol for the terabyte is TB.
