nybble n. 四位元组 四位元组 nybble n 1: a small byte [ synonym: { nybble}, { nibble}] { nibble} nybble: / nib´ l/, nibble, n. [ from v. nibble by analogy with ‘ bite’ → ‘ byte’] Four bits; one hex digit; a half- byte. Though ‘ byte’ is now techspeak, this useful relative is still jargon. Compare byte; see also bit. The more mundane spelling “ nibble” is also commonly used. Apparently the ‘ nybble’ spelling is uncommon in Commonwealth Hackish, as British orthography would suggest the pronunciation / ni:´ bl/. Following ‘ bit’, ‘ byte’ and ‘ nybble’ there have been quite a few analogical attempts to construct unambiguous terms for bit blocks of other sizes. All of these are strictly jargon, not techspeak, and not very common jargon at that ( most hackers would recognize them in context but not use them spontaneously). We collect them here for reference together with the ambiguous techspeak terms ‘ word’, ‘ half- word’, ‘ double word’, and ‘ quad’ or quad word; some ( indicated) have substantial information separate entries. The fundamental motivation for most of these jargon terms ( aside from the normal hackerly enjoyment of punning wordplay) is the extreme ambiguity of the term word and its derivatives.
