- Types of program translator: Understand the role of each of the following: • assembler • compiler • interpreter. Explain the differences between compilation and interpretation. Describe situations in which each would be appropriate. Explain why an intermediate language such as bytecode is produced as the final output by some compilers and how it is subsequently used. Understand the difference between source code and object (executable) code. 74

Exam tips
- Use the translation sequence: For questions about bytecode, write the sequence clearly: source code, compiler, bytecode, then interpreter or virtual machine.
Common mistakes
- Confusing an interpreter with a compiler: State that an interpreter translates and executes source code during operation, whereas a compiler translates the source program before execution and produces translated output.
