machine code In computing, instructions that the central processing unit (CPU) of a computer can execute, without the need for translation. Machine-code statements are written in a binary-coded (low-level) computer language. Programmers usually write computer programs in a high-level language (such as FORTRAN or C), which a compiler program then translates into code for execution. See also binary system
