A zettabyte is a unit of measurement used by technology professionals and the general public to describe a computer or other device's storage capacity. The number of bytes is equal to 2 to the 70th power, also expressed as 1 sextillion bytes. One zettabyte is approximately equal to one thousand exabytes or one billion terabytes. The measurement zettabyte, along with other metric amounts, is determined by the International Electrotechnical Commission (IEC), an organization responsible for International Standards and Conformity Assessment for computer and electronic technologies. They set standards across technology including measurements for computer storage.Content Continues Below
As a unit of measurement for the storage of computer information, zettabytes measure data in binary form, the language used by most computers to interpret and synthesize information. The binary system in mathematics is used to translate regular numerals and characters to a system that a computer can understand and that can easily be electronically transferred. Binary is made up of groups of digits that are all either ones or zeros, and in combinations of sets of 8. The varying combinations of sequences of bits are codes that correlate to different letters and characters.
Zettabytes are used to describe data storage of extremely large amounts of information and code, also commonly referred to by technology professionals as big data. Big data might include any large amount of structured or unstructured data that is collected daily at rapid speeds. The analysis of big data is often called data science, or the study of the internet of things (IoT). The internet of things is more specifically a collection of computer and digital interfaces that work in tandem and share massive amounts of information over huge, interconnected networks.
The scale of big data and IoT is so massive that many operations occur via artificial intelligence (AI), with little to no human intervention or direction. AI within big data systems may be able to analyze zettabytes' worth of data and perform other actions like decision-making, translating, speech recognition, pattern recognition or machine learning.
