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.
Kibibyte (KiB)
The kibibyte, symbol KiB, is a binary unit equal to 1,024 bytes, introduced by the International Electrotechnical Commission (IEC) in 1998. The unit addresses the difference between metric kilobytes (1,000 bytes) and binary kilobytes (1,024 bytes) in digital systems. Kibibytes are used in operating systems, file systems, and technical documentation for precise, unambiguous measurement. This clarity supports accurate handling of digital memory and storage.
