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

The petabit is a multiple of the unit bit for digital information or computer storage. The prefix peta (symbol P) is defined in the International System of Units (SI) as a multiplier of 1015 (1 quadrillion, short scale), and therefore 1 petabit = 1015 bits = 1 000 000 000 000 000 bits = 1000 terabits. The petabit has the unit symbol Pbit or Pb.
