What is the unit of measurement for computer memory and storage?

The unit of measurement for computer memory and storage is primarily represented in bytes, with various prefixes indicating different sizes. A megabyte corresponds to 1,024 kilobytes or 1 million bytes, making it a common measurement used for specifying file sizes and memory capacity in personal computers and devices.

While gigabytes, kilobytes, and terabytes are also valid units, the megabyte is often referenced as a standard measure in various contexts, especially for smaller files or memory capacities. Understanding these distinctions is important when discussing data size, as the larger units (gigabytes and terabytes) are typically used for larger storage capacities, while kilobytes and megabytes can refer to smaller files. The correct choice reflects a foundational knowledge of how data is quantified in computing.
