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.

Bytes (B)

Definition

A byte (B) is a unit of digital information consisting of 8 bits. It is the standard addressable unit of memory in virtually all modern computer architectures.

History

The byte was introduced in the late 1950s by Werner Buchholz during the design of the IBM Stretch computer. Originally variable in size, the 8-bit byte became the de facto standard with the IBM System/360 in the 1960s.

Current use

Bytes are the base unit for measuring file sizes, memory capacity, and storage. Character encoding schemes like ASCII use one byte per character, while modern UTF-8 uses one to four bytes per character.
