Which language is written in binary code and directly executed by the CPU?

• A. High-level language
• B. Interpreter
• C. Machine Language
• D. Assembler

Answer: (C)

Machine language is the form that the processor can run directly. It consists of binary instructions that encode operations and their operands, and the CPU’s control unit fetches, decodes, and executes these instructions right away, with no translation step. High-level languages like Python or Java require a compiler or interpreter to translate them into machine code before the CPU can execute them, so they aren’t directly executable in binary form. An assembler turns assembly language (which uses mnemonics) into machine code, but the assembly language itself isn’t what the CPU executes; the final binary machine instructions are. The key point is that only machine language is written in binary and executed directly by the CPU.
