About these units
Block (block)
A block is a unit of data storage used by file systems, typically ranging from 512 bytes to 4096 bytes, though advanced systems may use even larger sizes (8 KB, 16 KB, etc.). Blocks form the fundamental allocation unit for disk storage—files occupy blocks on disk, and file systems track which blocks belong to which files. Block size has significant performance implications. Larger blocks improve read/write throughput but may waste space for small files (internal fragmentation). Smaller blocks offer precision but reduce I/O efficiency. Many classic file systems (FAT, ext2), modern ones (ext4, NTFS), and network storage systems (ZFS, Btrfs, distributed file systems) all rely on block-based allocation. Blocks bridge the gap between raw physical storage and abstract file structures.
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.
