Questions and Answers

What is the purpose of programming languages?

  • To allow the computer to give instructions to the programmer
  • To translate high level language into machine language
  • To enable the programmer to give instructions to the computer in a way that is understandable (correct)
  • To create a mapping between machine language and assembly language

    • Which statement best describes assembly language?

  • It does not need translation as it directly communicates with the computer
  • It requires rewriting for each machine due to differences in machine languages (correct)
  • It is translated into machine language by a program called a compiler
  • It is a high level language used for complex programming tasks

    • What does a compiler do in relation to high level languages?

  • Executes high level language directly without any translation
  • Translates high level language into machine language (correct)
  • Rewrites the program for different machines
  • Converts high level language into assembly language

    • Why were high level languages created?
