Abbreviated as MByte, meg, or mbit, MB is short for megabyte. An MB is a measurement used with computer storage media that can equal to 1,048,576 (220) bytes or 1,000,000 (106) bytes depending on the manufacturer of a hardware device or the developer of software.

Tip: When the "b" is lowercase (Mb), this refers to a megabit.
