Zettabyte (ZB)

A Zettabyte (ZB) is a unit of digital information storage equal to one sextillion bytes, or 102110^{21}1021 bytes. To put it into perspective, one zettabyte is equivalent to 1,000 exabytes or one billion terabytes. The term is often used to quantify the massive amounts of data generated globally, especially with the growth of big data, cloud computing, and the Internet of Things (IoT). Understanding data in zettabytes highlights the scale of data storage and transfer in today’s digital landscape.
