SLR15 | Programming Languages & Translators

Which of the following is considered a low level programming language?

• Python

• Assembly language

• Java

• Pascal

What does a compiler do?

• Executes code line by line

• Translates source code into object code

• Converts machine code to source code

• Stores data in memory

Which of the following is an example of a high level language?

• Machine code

• Assembly language

• C++

• Microcode

What is machine code?

• Human-readable instructions

• Binary instructions executed directly by the CPU

• Pseudocode for algorithms

• Source code written in Java

Which of the following best describes source code?

• The output of a compiler

• The original code written by a programmer in a high level language

• Binary code executed by the CPU

• The code produced by an assembler

What is the main function of an assembler?

• To translate high level code to machine code

• To translate assembly language into machine code

• To execute code line by line

• To optimise code for speed

Which of the following is true about object code?

• It is written by the programmer

• It is the output produced after source code is compiled

• It is always human-readable

• It is the same as source code

Which of the following is a characteristic of imperative high level languages?

• They focus on describing what the program should accomplish

• They use statements that change a program’s state

• They are only used for web development

• They cannot use variables

Which of the following best describes bytecode?

• Code that can only be run on a specific CPU

• Intermediate code that can be executed by a virtual machine

• Source code written in Python

• Machine code for a microcontroller

Which of the following is a key difference between an interpreter and a compiler?

• An interpreter translates the entire program at once, while a compiler translates line by line

• An interpreter translates and executes code line by line, while a compiler translates the entire program before execution

• Both perform the same function

• A compiler is only used for assembly language
