Understanding Compilers and Interpreters

What is the primary function of a compiler in computer science?

• To execute code line by line

• To translate high-level code into machine code

• To manage memory allocation

• To interpret byte code

Which of the following is a characteristic of an interpreter?

• It translates the entire program before execution

• It executes code line by line

• It generates object code

• It requires linking and loading

What is machine code?

• A high-level programming language

• A type of byte code

• A low-level code that is directly executed by the CPU

• A code used for virtual machines

What is object code?

• The source code written by a programmer

• The output of a compiler that is not yet executable

• The code executed by an interpreter

• The code used for debugging

What is byte code?

• A type of machine code

• A code that is interpreted by a virtual machine

• A high-level programming language

• A code used for linking libraries

Put the stages of compilation into the correct order

• Optimisation

• Linking

• Lexical analysis

• Code Generation

• Syntactical analysis

What is the purpose of lexical analysis in the compilation process?

• Create object or machine code

• Optimisation

• Check code meets the language rules

• Linking

• Add libraries to the executable program

• Syntactical analysis

• Improve performance & shrink executable

• Lexical Analysis

• Analyse source code & convert to tokens

• Code Generation

What is the role of a loader in the compilation process?

• To translate high-level code into machine code

• To execute the compiled code

• To load the compiled code into memory for execution

• To check for syntax errors

What is the function of linking in the compilation process?

• To execute the code

• To combine object code with libraries

• To interpret byte code

• To perform lexical analysis

Which of the following best describes a virtual machine (VM)?

• A physical machine that executes machine code

• A software emulation of a physical computer

• A tool for debugging code

• A type of compiler
