PB, which stands for PetaByte is a measure of memory or storage capacity and is 2 to the 50th power bytes in size. One PetaByte is roughly 100,000 GigaBytes. The breakdown of the "Byte" system is as follows:

B = 1 Byte = 8 bits

KB = KiloByte = 2 to the 10th power = 1,024 bytes

MB = MegaByte = 2 to the 20th = 1,048,576 bytes

GB = GigaByte = 2 to the 30th = 1,073,741,824 bytes

TB = TeraByte = 2 to the 40th = 1,099,511,627,776 bytes

PB = PetaByte = 2 to the 50th = 1,125,899,906,842,624 bytes

EB = ExaByte = 2 to the 60th = 1,152,921,504,606,846,976 bytes

ZB = ZettaByte = 2 to the 70th = 1,180,591,620,717,411,303,424 bytes

YB = YottaByte = 2 to the 80th = 1,208,925,819,614,629,174,706,176 bytes
