Mache unit A unit of radioactivity equivalent to 13.47 disintegrations per second (3.64 × 10–10 curie) per liter. It represents the concentration of radon gas per liter (when all radiation is absorbed) that will result in a saturation current of 10–3 esu (not to be confused with MACH NUMBER). machine address See ABSOLUTE ADDRESS. machine code See MACHINE LANGUAGE. machine cycle In a machine whose operation is periodic, a complete sequence constituting a period of operation. machine error In a computer or data-processing system, an error attributable to a hardware failure, rather than to a software fault. machine instruction A computer program instruction written in MACHINE LANGUAGE. machine knowledge General term for data stored in an artificially intelligent computer system, and the ability of the computer to use that data in meaningful ways. machine language Computer program instructions and data represented in binary form. In the hierarchy of programming languages, it is the lowest; the computer works directly with it. All high-level languages are translated to machine language by an assembler, compiler, interpreter, or monitor system. machine learning In artificial intelligence, a computer’s ability to learn through repeated calculations for particular problems. machine logic 1. The way that a computer’s functional parts are interrelated. 2. The facility whereby a computer solves problems. machine operation The performance by
