Hardware and Software Basics

What is a compiler?

• A compiler is a type of computer monitor

• A compiler is a hardware device used to store data

• A compiler is a tool for debugging software

• A compiler is a software program that translates code written in a high-level programming language into machine code.

Explain the difference between a compiler and an interpreter.

• A compiler translates code line by line, while an interpreter translates the entire program at once.

• A compiler directly executes the code, while an interpreter generates machine code.

• The main difference between a compiler and an interpreter is that a compiler translates the entire program into machine code before execution, while an interpreter translates and executes the code line by line.

• A compiler is used for high-level languages, while an interpreter is used for low-level languages.

Name a popular compiler used in programming languages.

• Eclipse Compiler

• Visual Studio Compiler

• LLVM (Low Level Virtual Machine)

• GCC (GNU Compiler Collection)

What is the role of an interpreter in software development?

• Interpreters are only used for debugging purposes in software development.

• The role of an interpreter in software development is to directly execute instructions written in a programming or scripting language without the need for compiling.

• Interpreters are not necessary in modern software development.

• The interpreter converts code into machine code during compilation.

How does a compiler convert source code into machine code?

• Source code analysis, code generation, optimization, translation to machine code

• Lexical analysis, syntax analysis, semantic analysis, intermediate code generation, optimization, and translation to machine code.

• Lexical analysis, syntax analysis, semantic analysis, intermediate code generation, optimization, and compilation to machine code

• Syntax analysis, semantic analysis, intermediate code generation, optimization, translation to machine code

Discuss the advantages of using a compiler over an interpreter.

• Using a compiler can result in faster execution and early error detection.

• Compilers do not support dynamic typing

• Compilers are harder to debug compared to interpreters

• Interpreters are more efficient than compilers

What is the main function of an interpreter?

• Translate and compile programming code

• Debug code errors

• Translate and execute programming code line by line

• Optimize code performance

Can a compiler and an interpreter be used together in a programming environment? If yes, explain how.

• Yes, a compiler and an interpreter can be used together in a programming environment.

• No, a compiler and an interpreter cannot work together

• Yes, but only if they are used on separate computers

• Yes, but only if they are from different programming languages

What are some examples of interpreted programming languages?

• Java

• C++

• Swift

• Python, Ruby, JavaScript, PHP

Explain the concept of Just-In-Time (JIT) compilation in relation to interpreters.

• JIT compilation in interpreters focuses on reducing memory usage rather than improving performance.

• JIT compilation in interpreters involves translating code into machine code at runtime for improved performance.

• JIT compilation translates code into assembly language directly in interpreters.

• JIT compilation involves pre-compiling code before runtime in interpreters.
