Question: 1 / 475

Which unit of data is considered the largest relative to digital technology?

Megabyte

Gigabyte

Terabyte

The largest unit of data among the options provided is the terabyte. In the hierarchy of digital data measurement, a terabyte is equivalent to 1,024 gigabytes. This scale shows that as we move up the measurement units, each step increases the storage capacity significantly.

A terabyte is an impressive capacity often used to measure data storage in larger systems, such as databases, cloud storage, and high-definition content. In contrast, a gigabyte is one step lower, equating to 1,024 megabytes, which means it holds less data than a terabyte.

While a pebibyte represents an even larger measurement, it is not as commonly referenced in standard data storage terminology compared to terabytes in everyday use. Therefore, in the context of general information technology and data storage, the terabyte stands out as the largest unit listed among the choices.
