Byte addressing might still need to access 8-bit data over its 64-bit address line, and have the data returned in the bottom 8 bits of its longer data line. Byte addressable memory refers to architectures where data can be accessed and addressed in units that are narrower than the bus. An eight-bit processor like the Intel 8008 addresses eight bits, but as this is the full width of the bus, this is regarded as word-addressable. The 386SX, which addresses memory in 8-bit units but can fetch and store it 16 bits at a time, is termed byte-addressable. Bytes have not always meant
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
