hash bucket

hash bucket n.  A notional receptacle, a set of which might
   be used to apportion data items for sorting or lookup purposes.
   When you look up a name in the phone book (for example), you
   typically hash it by extracting its first letter; the hash buckets
   are the alphabetically ordered letter sections.  This term is used
   as techspeak with respect to code that uses actual hash functions;
   in jargon, it is used for human associative memory as well.  Thus,
   two things `in the same hash bucket' are more difficult to
   discriminate, and may be confused.  "If you hash English words
   only by length, you get too many common grammar words in the first
   couple of hash buckets." Compare {hash collision}.
