Morphology

MB = M + B

An abbreviation for 'megabyte'; the letter components do not transparently map to the unit meaning, so knowledge depends on knowing the abbreviation expansion.

Etymology

MB comes from mega (a prefix meaning 'large' or 'about a million') and byte (a unit of digital data). So an MB is a simple way to say a large amount of data—about one million bytes—used to measure file size and storage.
