Byte addressing 8 bits; in fact, depending on the platform, byte sizes of 1 to 48 bits have been used in the past. Therefore, the term "octet" is used where the context makes byte-length ambiguous. For example, in the 1980s, Honeywell mainframes had 36-bit words, and were byte-addressable in 9-bit bytes, or "nonets", They used 7- or 8-bit character codes, either of which were stored one to each 9-bit byte, making characters individually addressable. To illustrate why byte addressing is useful, consider the IBM 7094, which is word-addressable and has no concept of a byte. It has 36-bit words, and stores its
Quantum computing measurement, collapsing the system of qubits into one of the formula_2 eigenstates, where each qubit is zero or one, decomposing into a classical state. The outcome can, therefore, be at most formula_1 classical bits of information (or, if the algorithm did not end with a measurement, the result is an unobserved quantum state). Quantum algorithms are often probabilistic, in that they provide the correct solution only with a certain known probability. Note that the term non-deterministic computing must not be used in that case to mean probabilistic (computing) because the term non-deterministic has a different meaning in computer science. An
