Which of the following is true about a zettabyte?

A zettabyte is indeed equal to 1,000 exabytes, which is a significant measure of data storage capacity. This unit is part of a standardized set of prefixes used to denote varying amounts of digital data, where each prefix corresponds to a power of ten. To understand this in perspective, one exabyte equals 1 billion gigabytes, and a zettabyte stands at the next level, being 1,000 times larger than an exabyte.

This measurement is crucial, particularly in fields dealing with large-scale data such as cloud computing, big data analytics, and digital storage solutions. By recognizing that a zettabyte equals 1,000 exabytes, one can appreciate the vast scale associated with contemporary data generation and storage, as current global data volumes are approaching the zettabyte level.

The other options do not accurately define the zettabyte. It is not equivalent to 1 billion petabytes, nor is it a unit of storage equal to 1 billion terabytes, nor is it smaller than a gigabyte. Understanding these distinctions helps clarify the hierarchy of data measurements, reinforcing the importance of the zettabyte in the context of modern technology and data management.
