A megabyte (MB) is a unit of digital information, meaning one million bytes.
A byte, in turn, is made up of eight bits, which are the most basic unit of information in computing. A byte is a group of bits that store data and execute instructions.
Bit is short for binary digit, which means that it can only have one of two values, 0 or 1.
Megabytes are fairly small units of data in the context of most modern uses for computers.
