A GiB, or gibibyte, is a unit of digital information storage that equals 2^30 bytes, which is 1,073,741,824 bytes. It is part of the binary system used in computing, where data is often measured in powers of two. The term "gibibyte" was introduced to provide clarity and avoid confusion with the similar-sounding term "gigabyte," which is based on the decimal system. GiB is commonly used in contexts such as computer memory, hard drives, and data transfer rates. Understanding GiB is important for accurately assessing storage capacity and performance in devices like computers, smartphones, and servers.
