Gibibyte (GiB)
The gibibyte, symbol GiB, is a binary unit of digital information equal to 1,073,741,824 bytes (1,024 mebibytes). Introduced by the International Electrotechnical Commission (IEC) in 1998, it was created to clearly distinguish binary measurements from decimal-based gigabytes (GB), which can equal 1,000,000,000 bytes. Gibibytes are commonly used in operating systems, software engineering, and computer hardware specifications to ensure precise calculations for memory and storage. By using gibibytes, developers and IT professionals avoid ambiguity when reporting RAM, file sizes, and storage capacity, maintaining accuracy across platforms and systems.
Gigabyte (GB)
The gigabyte, symbol GB, represents 1,000,000,000 bytes in decimal, though in binary it is often approximated as 1,073,741,824 bytes (1,024 MiB). The unit was introduced in the 1980s as personal computers and hard drives increased capacity. Gigabytes measure larger data volumes, including software, multimedia, and storage devices, and became the standard for consumer storage, networking, and cloud computing as a scale between megabytes and terabytes.
