Yotta is a unit of measurement in the International System of Units (SI) that represents one septillion, or 10^24, of something. It is often used to quantify large amounts of data, such as in computing and data storage, where it can describe capacities like yottabytes. The term "Yotta" is derived from the Greek word "octo," meaning eight, as it is the eighth power of ten in the SI prefix system. Other related prefixes include kilo, mega, giga, tera, peta, exa, and zetta, which represent progressively smaller quantities.
