trit

[prev][up][next]
trit /trit/ /n./ [by analogy with `bit'] One base-3 digit; the amount of information conveyed by a selection among one of three equally likely outcomes (see also bit). Trits arise, for example, in the context of a flag that should actually be able to assume *three* values -- such as yes, no, or unknown. Trits are sometimes jokingly called `3-state bits'. A trit may be semi-seriously referred to as `a bit and a half', although it is linearly equivalent to 1.5849625 bits (that is, log2(3) bits).
