Megabytes (MB)

Definition

A megabyte (MB) is a decimal unit of digital information equal to 1,000,000 bytes (10⁶ bytes) in the SI system. In computing contexts, it is sometimes loosely used to mean 1,048,576 bytes (2²⁰).

History

The megabyte became commonly used in the 1980s as floppy disks and early hard drives reached capacities in this range. Marketing and technical usage diverged, prompting the IEC to formalize the mebibyte (MiB) for the binary interpretation.

Current use

Megabytes are used daily to express image sizes, music file sizes, app sizes, and mobile data plans. Storage manufacturers, ISPs, and software developers use the decimal MB as standard.

Kilobytes (KB)

Definition

A kilobyte (KB) is a decimal unit of digital information equal to 1,000 bytes, as defined by the International System of Units (SI). It should not be confused with the kibibyte (KiB), which equals 1,024 bytes.

History

The kilobyte emerged in the early days of computing. Initially, it was informally used to mean 1,024 bytes (2¹⁰), but the IEC standardized the distinction in 1998, reserving 'kilobyte' for 1,000 bytes and introducing 'kibibyte' for 1,024 bytes.

Current use

Kilobytes are used by storage manufacturers and telecom standards to express small file sizes, cache sizes, and data transfer quantities using the decimal (SI) convention.
