Understanding Interpreters, Assemblers, and Compilers

What does an interpreter do?

• Translates the entire program into machine code in one go

• Translates each line of HLL code into machine code

• Converts assembly language instructions into machine code

• Saves a copy of the translated code

What is one advantage of an interpreter?

• It translates the entire program at once.

• Errors are displayed only at the end of the process.

• It requires less main memory.

• It is not useful for debugging programs.

Why is an interpreter useful for applications on multiple platforms?

• It creates one line of machine code for each instruction.

• It translates assembly language to machine code.

• It interprets the program each time it is run.

• It saves a copy of the translated code for reuse.

What happens when an interpreter encounters an error?

• The error is ignored, and the program continues to run.

• Execution stops immediately.

• The entire program is compiled.

• The error is reported only at the end of the process.

What does an assembler do?

• Translates each line of HLL code into machine code.

• Converts assembly language instructions into machine code.

• Translates the entire program into machine code.

• Interprets the program each time it is run.

Which of the following is true about an assembler?

• It does not convert the entire program into machine code in one go.

• It creates one line of machine code for each assembly-language instruction.

• It requires more main memory to run.

• It is suitable for larger programs like computer games.

What is the key feature of a compiler?

• It translates the entire program into machine code at once.

• It interprets the program each time it is run.

• It creates one line of machine code for each instruction.

• It does not save a copy of the translated code.

Why can debugging be difficult with a compiler?

• Errors are displayed as soon as they are encountered.

• Errors are reported only at the end of the process.

• It carries out one instruction before translating the next.

• It translates only a single line of code at a time.

What is one disadvantage of a compiler?

• It takes a long time to compile the program.

• It requires more main memory than an interpreter.

• It cannot run the program on multiple platforms.

• It is not suitable for larger programs.

Why is a compiler suitable for larger programs?

• It translates only one line at a time.

• It saves a copy of the translated code for reuse.

• It encounters errors immediately while executing.

• It requires less main memory.
