{synonym}
A <bit> is a binary classical symbol with two distinguishable values, zero and one. A uniform random <bit> has one <bit> of <information entropy>, while a biased binary symbol has less. Sending one <bit> means transmitting one symbol from this binary alphabet; the <mutual information> it carries about a particular input need not be one.
