Question:
Which of the following languages does computer understand
Which of the following languages does computer understand
Show Hint
Every programming language, regardless of how advanced or abstract it is, must ultimately be compiled, interpreted, or assembled into binary machine language before the physical CPU can execute it.
Updated On: Jul 24, 2026
- Machine language
- C language
- Assembly language
- BASIC language

The Correct Option is A
Solution and Explanation
Step 1: Understanding the Concept:
At the hardware level, a computer's central processing unit (CPU) is composed of digital electronic circuits containing millions of transistors operating as binary switches. These circuits can only process electrical signals corresponding to two states: high voltage (represented as 1) and low voltage (represented as 0).
Step 2: Detailed Explanation:
Any instruction executed by the CPU must be provided in the form of binary sequences (strings of 0s and 1s). This fundamental level of instruction is known as machine language.
Let us review the options to understand why they differ:
Machine Language: This is the lowest level of programming language. It is the only language that the computer's CPU can directly decode and execute without any intermediate translation or compilation. It is highly hardware-specific.
Assembly Language: This is a low-level language that introduces mnemonic codes (such as ADD, SUB, MOV) in place of raw binary sequences to make programming easier for humans. However, a computer cannot run this directly; it must be translated into machine code using a utility program called anassembler.
C and BASIC Languages: These are high-level programming languages that use English-like syntax and algebraic notations. They are designed to be portable across different hardware architectures. To run on a computer, the source code must be translated into machine code using acompiler or aninterpreter.
Consequently, machine language is the only language a computer understands natively.
Step 3: Final Answer:
The language that a computer directly understands is Machine language, which is Option (A).
