About these units
DVD (1 layer, 2 side) (DVD (1L, 2S))
A single-layer, double-sided DVD offers 9.4 GB, with 4.7 GB per side, requiring the user to physically flip the disc. Double-sided DVDs were ideal in early DVD-era box sets and archival applications, but their inconvenience—no label side, no artwork, and manual flipping—limited consumer adoption. They represent a transitional form of optical media designed to increase capacity before dual-layer technologies became mainstream.
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.
