YiB

YiB is an acronym that can refer to several different terms depending on context. There is no single, universally accepted meaning for YiB, and its interpretation is usually clarified by the surrounding text or field.

In computing and data storage, YiB most commonly denotes yobibyte, a binary unit of information equal to 2^80 bytes. It is part of the IEC binary prefix family, which also includes KiB, MiB, GiB, TiB, PiB, EiB, and ZiB. One yobibyte equals 1,208,925,819,614,629,174,706,176 bytes. This unit is used mainly in technical discussions of very large storage capacities and theoretical limits, and it is distinct from decimal-based prefixes such as the exabyte.

In publishing, journalism, and organizational reporting, YiB is sometimes used as an abbreviation for Year in Brief, a concise annual summary of events, metrics, and outcomes. A Year in Brief can be produced by companies, nonprofits, or research teams to present key highlights without the length of a full annual report.

Other uses exist as well, as many local organizations, programs, or events may adopt YiB as an acronym in their names. Because the meaning of YiB varies with context, readers should rely on nearby definitions or clarifying information to determine the intended sense. Related terms include the broader set of binary prefixes used in data measurement and, in non-technical contexts, common acronyms formed from year-end or annual summaries.
