Translators and Interpretors

Question 1

What is a compiler?

Answer 1

• Translate HLL/source code into machine code
• Will attempt to translate source code into machine code all at once
• If it succeeds, it will create object code or if it fails, generate an error report without running lines of code

Question 2

What is a Interpreter?

Answer 2

• Translates HLL/source code into machine code
• It will translate and execute one line at a time
• If error is found, the program will stop and only continue once all errors have been resolved
• No object code is produced

Question 3

What is an Assembler?

Answer 3

• Converts assembly code into machine code
• Similar to compiler, it will attempt to translate the whole program all at once
• If it succeeds, it will create object code, if it fails, it will generate an error report without running any lines of codes
