Machine code (機械語) is the collective term for computer languages written in bits that a CPU can directly decode and execute. Machine code is the lowest-level concept for representing a program.
Machine code can be used 1:1 with assembly language. In other words, in computer programming, machine code is mostly written by way of assembly language. Before assembly language was created, programs were sometimes written by entering machine code directly, and even today, though rare, some people still do so. Machine code differs depending on the type of CPU.
