About these units

Byte (B)

A byte consists of 8 bits, forming the standard grouping used in computing for representing characters, numbers, and machine instructions. This 8-bit size became dominant due to hardware design choices in early microprocessors, especially the IBM System/360 architecture. Bytes allow computers to represent values from 0 to 255, enabling ASCII encoding, color values, file metadata, and vast amounts of structured data. The byte is the basis for nearly all storage units—kilobytes, megabytes, gigabytes—and remains the fundamental digital "counting unit" for memory, disk space, and network transfers.

Petabyte (PB)

A petabyte is 1 quadrillion bytes in decimal (10¹⁵) or 1,125,899,906,842,624 bytes in binary (2⁵⁰). At this size, storage enters the realm of massive data infrastructures: internet archive collections, large-scale scientific simulations, genomic sequencing databases, machine learning datasets containing billions of records, multinational cloud storage networks. A single PB can store thousands of HD films, millions of e-books, or extensive enterprise backups. Petabytes mark the transition from everyday computing into large-scale data engineering, distributed systems, and global information ecosystems.
