SCSI high byte termination case where there is only one 16-bit (wide) device connected to one or more 8-bit (narrow) devices. Then it is possible to wire all the eight spare data bits and the ninth parity bit together and to terminate them with a single resistor circuit to TERMPOWER. So in the case of a differential SCSI bus, it is possible to terminate all 18 spare signal wires with just one resistor. This method is not considered good practice, but has been successfully used in some SCSI products. SCSI high byte termination In SCSI computer systems, there is a special case with mixed
Quantum computing Quantum computing Quantum computing is computing using quantum-mechanical phenomena, such as superposition and entanglement. A quantum computer is a device that performs quantum computing. Such a computer is different from binary digital electronic computers based on transistors. Whereas common digital computing requires that the data be encoded into binary digits (bits), each of which is always in one of two definite states (0 or 1), quantum computation uses quantum bits or qubits, which can be in superpositions of states. A quantum Turing machine is a theoretical model of such a computer and is also known as the universal quantum computer.
