What is the order of digital storage sizes from largest to smallest?

The correct order of digital storage sizes from largest to smallest is Yottabyte, Zettabyte, Exabyte.

This order is based on the established hierarchy of digital storage units, where each successive term represents a factor of approximately a thousand times the previous unit, specifically in the context of binary prefixes.

A Yottabyte is the largest of the three, representing (10^{24}) bytes. Following that is the Zettabyte, which equals (10^{21}) bytes. The Exabyte comes next, corresponding to (10^{18}) bytes. This structured decrease in magnitude illustrates how data size classifications are organized, with the largest unit being at the beginning and the smallest at the end.

Understanding this hierarchy is crucial, especially when discussing data storage capabilities or cloud storage solutions in the realm of AI and cognitive project management, as it relates to the scalability and efficiency of handling large datasets.

The other options misplace the order of these storage units, indicating a potential lack of clarity on the hierarchical structure of digital storage sizes. This proper understanding is key in industry discussions and applications.
