About these units
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.
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.
