Memory Unit Comparison
Computer memory is measured in various units, each representing a different magnitude of data. Understanding the hierarchy helps in identifying the largest unit.
Memory Unit Hierarchy
The units provided are standard prefixes for digital information. Their order by size, from smallest to largest, is as follows:
- Petabyte (PB)
- Exabyte (EB)
- Zetabyte (ZB)
- Yottabyte (YB)
Largest Memory Unit Identification
Comparing the units:
- A Petabyte is 1000 Terabytes.
- An Exabyte is 1000 Petabytes.
- A Zetabyte is 1000 Exabytes.
- A Yottabyte is 1000 Zetabytes.
Based on this standard hierarchy, Yottabyte is significantly larger than Petabyte, Exabyte, and Zetabyte.
Therefore, Yottabyte is the largest unit of memory among the given options.
