tebi

Tebi (Ti) is a binary prefix in the International System of Units (SI) that represents 2^40 or 1,099,511,627,776 in decimal. It is the largest binary prefix currently in use.

The term "tebi" was first proposed in 1998 by the International Electrotechnical Commission (IEC) to provide a clear and unambiguous way to represent very large quantities of binary data. Prior to the adoption of tebi, the prefix "tera" was often used to represent 2^40, even though its official definition is 10^12. This led to confusion and ambiguity, as the same prefix could be used to represent two different values.

The adoption of tebi has helped to clarify the meaning of SI prefixes and to avoid confusion when dealing with very large quantities of binary data. It is now the preferred prefix to use when representing 2^40, and it is becoming increasingly common in technical literature and software documentation.
