Machine language: The programming language that is directly recognized by computer hardware. What makes up such a program is a machine instruction, which is a binary coded instruction, that is, the code contains only a binary 0 or 1, such as 1110011000110011 is a machine instruction. Since computers are mainly composed of digital circuits, machine commands are directly memorized, transmitted, recognized, and processed by computers.

Machine languages, known as first-generation languages, are not only complex and difficult to remember, but also depend on specific models. The program is extremely difficult to write, debugging and modifying, and it is impossible to port between different models. No one has written programs in machine language for a long time.
