Noun
a unit of information equal to 1024 kibibytes or 2^20 (1,048,576) bytes
Source: WordNetFor example, 1.44 MB 3½-inch HD disks have the "M" prefix peculiar to their context, coming from their capacity of 2,880 512-byte sectors (1,440 KiB), inconsistent with either a decimal megabyte nor a binary mebibyte (MiB). Source: Internet
In 1998 the International Electrotechnical Commission (IEC) proposed standards for binary prefixes requiring the use of megabyte to strictly denote 1000 2 bytes and mebibyte to denote 1024 2 bytes. Source: Internet
In the IEC system, these would be expressed as one "mebibyte" and one "gibibyte," respectively. Source: Internet
The only significant change is the addition of explicit definitions for some quantities. citation In 2009, the prefixes kibi-, mebi-, etc. were defined by ISO 80000-1 in their own right, independently of the kibibyte, mebibyte, and so on. Source: Internet
