Types of Program Translator

A program that converts assembly language into machine code is called a(n) ______.

• Compiler

• Interpreter

• Assembler

• Linker

Answer explanation

An assembler is a program that translates assembly language, which is a low-level programming language, into machine code, the binary code that a computer's processor can execute. Thus, the correct answer is 'Assembler'.

What is the main difference between a compiler and an interpreter?

• A) A compiler translates code all at once, while an interpreter translates code line by line.

• B) A compiler is faster than an interpreter.

• C) An interpreter translates code all at once, while a compiler translates code line by line.

• D) An interpreter is faster than a compiler.

Answer explanation

The main difference is that a compiler translates the entire code at once into machine code, while an interpreter translates it line by line during execution. Therefore, option A is correct.

An assembler is a type of ______.

• Compiler

• Interpreter

• Program translator

• Text editor

Answer explanation

An assembler translates assembly language into machine code, making it a type of program translator. Unlike compilers and interpreters, which handle higher-level languages, assemblers work directly with low-level code.

The role of an Assembler in programming languages is to convert (a)   to machine code.

• Converts high-level code to machine
• Converts assembly code to machine c
• Converts machine code to high-level
• Converts bytecode to machine code.

Answer explanation

An assembler translates assembly code, which is a low-level programming language, into machine code that a computer's processor can execute. This makes the correct answer "Converts assembly code to machine code."

What is the primary function of a Compiler?

• Executes code line by line

• Translates entire code to machine code at once

• Converts machine code to high-level code

• Converts bytecode to source code.

Answer explanation

The primary function of a compiler is to translate the entire source code into machine code at once, allowing the program to be executed efficiently. This distinguishes it from interpreters, which execute code line by line.

Match the following roles with their descriptions.

• Identifying grammatical mistakes in code

• Optimizing code for performance

• Improving code efficiency and speed

• Translating code to machine code

• Converting high-level language to low-level language

• Executing code line by line

• Interpreting code without prior compilation

• Checking syntax errors.

Answer explanation

The correct choice is 'Executing code line by line' because a compiler translates code into machine code, optimizes it, and checks for syntax errors, but it does not execute the code. That is the role of an interpreter.

What is the relationship between assembly language instructions and machine code instructions in an assembler?

• 1-to-2

• 1-to-1

• 2-to-1

• 1-to-3

Answer explanation

Assembly language instructions correspond directly to machine code instructions, meaning each assembly instruction translates to exactly one machine code instruction. Therefore, the relationship is 1-to-1.

Compilers translate programs written in (a)   into machine code.

• Assembly language
• High-level languages
• Machine code
• Source code

Answer explanation

Compilers primarily translate programs written in high-level languages, such as C or Java, into machine code. Assembly language is a low-level representation, while machine code is the output itself. Source code refers to the original program.

Which type of translator is said to be platform specific?

• Interpreter

• Compiler

• Assembler

• Emulator

Answer explanation

An assembler translates assembly language into machine code specific to a particular platform, making it platform-specific. In contrast, interpreters and compilers can be more portable across different systems.

What is the main difference in how compilers and interpreters handle source code errors?

• A) Compilers check errors line-by-line before translating, while interpreters begin translation immediately.

• B) Interpreters check errors line-by-line before translating, while compilers begin translation immediately.

• C) Both compilers and interpreters check errors line-by-line before translating.

• D) Neither compilers nor interpreters check errors before translating.

Answer explanation

Compilers analyze the entire source code and check for errors before translating it into machine code, while interpreters start executing the code immediately, checking for errors line-by-line during execution. Thus, A is correct.
