Root Explanation

**Petabyte** → It is formed from "peta-" (from the Greek "penta", meaning five) and "byte" (a unit of digital information). The word "petabyte" refers to a unit of digital information that is equivalent to 1,024 terabytes, or 2^50 bytes, which is five orders of magnitude larger than a byte.

Memory Tip

Think of 'peta-' meaning five, and remember that a petabyte is a massive amount of data, specifically five levels larger than a byte.
