About these units
Bit (b)
A bit is the most fundamental unit of digital information, representing a binary value of 0 or 1. In physical systems, a bit corresponds to two distinguishable states—such as high/low voltage, magnetic polarity, or light/dark in optical systems. Bits form the basis of all digital computation: CPUs manipulate bits through logic gates, memory stores bits in capacitors or magnetic cells, and communication networks transmit bits as electrical pulses or photons. Although extremely small in size, bits accumulate into vast structures—from kilobytes of text to petabytes of cloud storage. Every digital phenomenon—files, images, videos, software—ultimately reduces to sequences of bits. The bit is the "atom" of information.
Petabyte (10^15 bytes) (PB (10^15))
A decimal petabyte equals 1 quadrillion bytes, a capacity used in cloud data centers, AI training sets, and global archival projects. Organizations like scientific research institutes, major cloud providers, and financial institutions routinely manage petabyte-scale data, requiring specialized infrastructure, redundancy strategies, and data governance. The shift from terabytes to petabytes marks a tipping point where storage strategy must incorporate distributed systems, advanced compression, and scalable metadata management.
