About these units
Kilobyte (10^3 bytes) (kB (10^3))
A decimal kilobyte equals 1,000 bytes, reflecting the SI prefix kilo = 10³. Storage device manufacturers standardize on this definition because it scales cleanly and simplifies marketing and specification. This creates a mismatch with binary kilobytes (1,024 bytes) historically used in RAM and file systems. As storage capacities grew, this discrepancy became increasingly noticeable, leading standards bodies to promote explicit binary prefixes (KiB, MiB) for clarity. Despite these efforts, decimal kilobytes remain dominant in contexts such as hard drives, flash memory packaging, and communication standards.
MAPM-Word (MAPM-word)
A MAPM-word refers to a word-size unit used in certain legacy mainframe and specialized computing systems; MAPM architectures often used 36-bit or 48-bit word sizes, enabling high-precision arithmetic and scientific calculation. These larger word widths were crucial before floating-point standards matured, giving scientists more numerical accuracy in simulations, engineering computations, and cryptographic calculations. Although modern systems have largely standardized on 32- and 64-bit words, MAPM-word units reflect computing's experimental phase, when designers tailored architectures to unique scientific, military, or industrial needs. Understanding such units is essential for interpreting old software, data formats, and archival system documentation.
