Question 69 of 319

Which of the following programming languages needs no translator for it to run?

  • A. High-Level Language
  • B. Low Level Language
  • C. Machine Language
  • D. Assembly Language

Correct Answer: C

Explanation
The correct option is C. Machine Language. Detailed Explanation
  1. Understanding Programming Languages:
  2. Programming languages can be categorized into different levels based on their abstraction from machine code. The two main categories are high-level languages and low-level languages.
  3. High-level languages (like Python, Java, and C++) are designed to be easy for humans to read and write. They require a translator (compiler or interpreter) to convert the code into machine language that the computer can understand.
  4. Low-level languages are closer to machine language and include assembly language and machine language itself.
  5. Machine Language:
  6. Machine language is the lowest level of programming language and consists of binary code (0s and 1s) that the computer's hardware can directly execute.
  7. Since machine language is the native language of the computer's CPU, it does not require any translation. The CPU can directly interpret and execute the instructions written in machine language.
  8. Why Other Options Are Incorrect:
  9. A. High-Level Language:
    • High-level languages are designed for ease of use and readability. They require a translator (compiler or interpreter) to convert the code into machine language before it can be executed by the computer. Therefore, they cannot run without a translator.
  10. B. Low Level Language:
    • Low-level languages include both machine language and assembly language. While machine language does not need a translator, assembly language does. Assembly language is a symbolic representation of machine language and requires an assembler to convert it into machine code. Thus, it cannot run without a translator.
  11. D. Assembly Language:
    • Assembly language is a low-level programming language that uses mnemonics and symbols to represent machine-level instructions. It is more human-readable than machine language but still requires an assembler to translate it into machine code. Therefore, it cannot run without a translator.
Summary of Key Points
  • Machine Language is the only programming language that does not require a translator to run, as it is directly executed by the CPU.
  • High-Level Languages and Assembly Language both require translation (compilation or assembly) to convert their code into machine language.
  • Understanding the hierarchy of programming languages helps clarify why machine language is unique in its ability to run without translation.
Revision Summary
  • Machine language is the only language that runs directly on the hardware without a translator.
  • High-level languages and assembly language require compilers or assemblers to convert code into machine language.
  • Machine language consists of binary code, while assembly language uses mnemonics.
  • Recognizing the differences between these language types is crucial for understanding how programs are executed on computers.
