About Gigabyte (GB)

A unit of digital storage equal to 1,073,741,824 bytes (= 1,024³ = 2³⁰ bytes) in the binary (computing) convention, or 1,000,000,000 bytes (= 10⁹) in the decimal (SI marketing) convention — the difference of 7.4% explains why a hard drive marketed as '1 TB' shows as '931 GB' in operating-system reporting. Reference values: a typical modern smartphone storage 64-512 GB (iPhone 15 base 128 GB, Pro Max up to 1 TB; Galaxy S24 base 256 GB); typical laptop SSD 256 GB - 2 TB; consumer USB flash drive 16-512 GB; the entire English Wikipedia text + images compressed ~50 GB; a 4K 60-fps movie file in H.265 ~30-50 GB for a 2-hour film; a Blu-ray disc 25 GB (single layer) or 50 GB (dual layer); the Internet Archive's Wayback Machine total ~99 PB (~99,000,000 GB). The gigabyte is the dominant working unit for consumer storage in 2020s+ technology — laptops, phones, USB drives, gaming consoles (PS5 + Xbox Series X both ship with 825 GB - 1 TB internal NVMe).

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).

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). 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).
