Which measurement comes before gigabyte in data size hierarchy?

In the data size hierarchy, a gigabyte (GB) is preceded by a megabyte (MB). The hierarchy progresses from smaller units to larger units, where:

• A kilobyte (KB) is 1,024 bytes.

• A megabyte (MB) is 1,024 kilobytes.

• A gigabyte (GB) is 1,024 megabytes.

This means that in terms of scale, one gigabyte is significantly larger than one megabyte, with the relationship being that one gigabyte is equivalent to 1,024 megabytes. Therefore, megabyte is the correct answer to identify the measurement that comes directly before gigabyte in this hierarchy.
