What are programs written in binary code called?

High-level language Assembly Language Machine Language Source Code

Correct Answer:

Machine Language

Explanation:

Machine language is the set of instructions encoded in binary that a computer’s CPU can execute directly. Because the processor understands only 0s and 1s, programs ultimately run in this form after any translation from higher-level representations. Assembly language, by contrast, uses human-friendly mnemonics to represent those same instructions and must be translated into machine language by an assembler. Source code refers to the human-readable form written in high-level languages (like C or Python) or in assembly before it’s turned into machine language. High-level languages are designed for humans and require a compiler or interpreter to convert them into machine code. So, programs written in binary code are called machine language.
