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.
Word (word)
A word is a unit of data whose size depends on the computer architecture, traditionally 16 bits but now often 32 or 64 bits. The word size determines the natural chunk of data a processor handles in a single operation, affecting register width, memory addressing, arithmetic precision, and overall system performance. As architectures evolved from early 8-bit systems to modern 64-bit CPUs, the meaning of "word" expanded too. Words are deeply tied to machine instructions, where addressing modes, opcodes, and data structures rely on word alignment. Thus, the word is both a conceptual and structural building block for computing hardware.
