machine language

A language that need not be modified, translated, or interpreted before it can be used by the processor for which it was designed. Note 1: The operation codes and addresses used in instructions written in machine language can be directly sensed by the arithmetic and control unit circuits of the processor for which the language is designed. Note 2: Instructions written in an assembly language or a high-level language must be translated into machine language before they can be executed by a processor. Note 3: Machine languages are usually used by computer designers rather than computer users.
