petabit
Massive data unit
A petabit is a unit of digital information equal to one quadrillion bits, or 10¹⁵ bits.
The prefix peta- denotes this massive scale, used primarily when measuring data transfer rates or network capacity: The undersea cable can handle several petabits per second.
Abbreviated Pb or Pbit.
