Byte explicitly denotes a sequence of eight bits, eliminating the ambiguity of the byte. The term "byte" was coined by Werner Buchholz in June 1956, during the early design phase for the IBM Stretch computer, which had addressing to the bit and variable field length (VFL) instructions with a byte size encoded in the instruction. It is a deliberate respelling of "bite" to avoid accidental mutation to "bit". Another origin of "byte" for bit groups smaller than a machine's word size (and in particular groups of four bits) is on record by Louis G. Dooley, who claimed he coined the term
Stochastic computing of generating random biased bit streams. In practice, these streams are generated with pseudo-random number generators. Unfortunately, generating (pseudo-)random bits is fairly costly (compared to the expense of, e.g., a full adder). Therefore, the gate-level advantage of stochastic computing is typically lost. Third, the analysis of stochastic computing assumes that the bit streams are independent (uncorrelated). If this assumption does not hold, stochastic computing can fail dramatically. For instance, if we try to compute formula_19 by multiplying a bit stream for formula_3 by itself, the process fails: since formula_21, the stochastic computation would yield formula_22, which is not generally true
