DEFINITION 4
The megabyte is a multiple of the unit byte for digital
information storage or transmission with three different
values depending on context: bytes (106, see prefix mega-)
generally for computer storage or transmission rates; bytes
(220, 1024 kilobytes or a mebibyte) generally for computer
memory; and in rare cases () bytes.
