About Byte (B)
The standard unit of digital information storage per IEC 80000-13:2008 (Quantities and units — Information science and technology). A byte is 8 bits — the smallest addressable unit on most modern computer architectures (x86, ARM, RISC-V, POWER) and the natural unit for storing a single ASCII character (US-ASCII 1968 standard, codes 0-127) or a single byte of UTF-8 (variable-length 1-4 byte Unicode encoding per RFC 3629). The 8-bit byte became the de facto standard with IBM System/360 (1964) and was formalized by ISO/IEC 2382-1 + the C99 + C++03 language standards. Historical systems used different byte widths: 6-bit (CDC 3000, Univac 1100), 7-bit (DEC PDP-10), 9-bit (DEC PDP-12, Honeywell 6000). Reference values: 1 byte stores 1 ASCII character, 2-4 bytes for Unicode/UTF-8/UTF-16/UTF-32, 8 bytes for a 64-bit integer or double-precision float (IEEE 754).
About Petabyte (PB)
A unit of digital storage equal to 1,125,899,906,842,624 bytes (= 1,024⁵ = 2⁵⁰ bytes) in the binary (computing) convention, or 10¹⁵ = 1,000,000,000,000,000 bytes in the decimal (SI marketing) convention. Reference values: the global daily Twitter/X firehose ~6 TB/day = ~2 PB/year of public tweets; Netflix's total catalog encoding ~3 PB (about 14,000 titles × multiple resolutions and codecs); the entire printed collection of the US Library of Congress ~10 TB digitized = 0.01 PB (a single petabyte holds 100× the LoC); the Internet Archive total holdings ~99 PB (text + images + videos + software); Facebook/Meta photo storage adds ~600 TB/day = ~0.6 PB/day; YouTube uploads ~500 hours of video per minute = ~720,000 hours/day, generating estimated petabytes/day of new video at H.264 bitrates. The petabyte is the working unit for hyperscale cloud storage (AWS S3, Google Cloud Storage, Azure Blob), data-center file systems (Lustre, GPFS, IBM Spectrum Scale, Ceph), and scientific computing (LHC, SKA radio telescope, Square Kilometre Array, Vera Rubin Observatory).

Understanding Bytes
The Byte (symbol: B) is a unit of data storage. The standard unit of digital information storage per IEC 80000-13:2008 (Quantities and units — Information science and technology).
