Question

A CPU understands instructions that are written only in what language?

Short answer

Answer: A CPU understands instructions that are written in machine language, also known as binary code or machine code, which consists of binary digits (0s and 1s).

Step-by-step solution

Definition of CPU

CPU (Central Processing Unit) is the primary component of a computer that performs most of the processing inside the machine. It is responsible for carrying out the instructions and operations of a computer program.

Language CPU Understands

A CPU understands instructions that are written in machine language, also known as binary code or machine code. This language consists of binary digits (0s and 1s), which represent electrical signals in a digital system.

Role of Assembly Language

Although machine language is not human-readable, programmers often use an intermediate language called assembly language, which represents machine code instructions using a more readable syntax. An assembler then translates assembly language instructions into machine language, making them understandable by the CPU.
