A yobibyte (YiB) is a unit of digital information equal to \(2^{80}\) bytes, or \(1,208,925,819,614,629,174,706,176\) bytes. It is the binary equivalent of a decimal yottabyte (YB) and represents a massive amount of data storage, used to measure data in the realm of cloud computing and future technologies. 

Key features of a yobibyte Composition: One yobibyte is equal to 1,024 zebibytes (\(1024^{8}\) bytes).Value: It is equivalent to \(1,208,925,819,614,629,174,706,176\) bytes, or \(2^{80}\) bytes.

Purpose: The term was standardized by the International Electrotechnical Commission (IEC) to provide a precise binary measurement for extremely large data sets, distinct from the decimal yottabyte.

Context: Yobibytes are relevant in contexts like cloud computing where massive amounts of data are stored and managed, such as on Amazon Web Services (AWS).

Comparison to yottabyte: While often used interchangeably, a yottabyte is a decimal unit equal to \(10^{24}\) bytes, whereas a yobibyte is a binary unit equal to \(2^{80}\) bytes. The yobibyte is slightly larger than the yottabyte.
