  • In modern data centers, storage capacities are often measured in Pb, reflecting the vast amounts of information handled.

Examples

  • To manage the significant traffic, the network was upgraded to support speeds of up to 10Pb, enhancing overall performance.

  • Tevatron Run II produced one Higgs for every 1/pb.

  • Tevatron Run I would have required a few fb for each Higgs and only reached 150 pb, so assume it did not make one.

  • The cross-section for that at the LHC is a few pb, and at the Tevatron a few fb.

  • If the Tevatron run I production cross-section was more like 0.1 pb, as these plots suggest, then it would have started producing them around the beginning of 1993 with about 10 pb.

  • And indeed, if you look closely, the cross-section for Run I at 125 GeV is about 0.6 per pb, not 0.1.

  • The data transmission rate reached a staggering 5Pb per second, allowing for rapid communication between devices.

Surface Forms

Pb singular
Pbs plural

Morphology

Pb = bit (semi-transparent) = P + b

Formed from the SI prefix 'P' (peta, 10^15) plus 'bit'; the composition is clear but understanding the magnitude requires knowledge of SI prefixes and case-sensitivity.

Etymology

Pb for data is made from the prefix peta, meaning 'one quadrillion' (1,000,000,000,000,000), and the b for 'bit', the smallest unit of digital information. So, like GB or MB, Pb names a size of data — a very, very large number of bits called a 'petabit'.
