MEG stands for Megabyte, which is a unit of measurement for digital information and is equal to one million bytes. BYTE stands for Binary Term, which is a unit of measurement for digital information and is equal to eight bits. BIT stands for Binary Digit, which is the smallest unit of digital information and is either a 0 or 1. MEGABYTE stands for Megabyte, which is equal to one million bytes.
