A programmer can use translators, such as an interpreter and a compiler, when developing a computer program.

Mark scheme

Marking points from the official mark scheme (Oct/Nov 2021). The mark or mark type is shown in brackets.

1. 6(a) Any one from: - They both translate high-level language into machine code / low-level language; - They both check for errors; - They both report errors
2. 6(b) Four from (Max 2 per translator): - An interpreter translates and executes the code line by line; - whereas a compiler translates and executes the whole code all in one go; - An interpreter stops translating and reports an error as it finds one; - whereas a compiler produces an error report at the end of translation; - An interpreter does not produce an executable file; - but a compiler does produce an executable file; - An interpreter will execute the code until it finds an error; - whereas a compiler will not execute any code if there are errors present; - An interpreter allows correction of errors in real-time; - whereas a compiler needs to retranslate the code each time after errors are found and corrected
3. 6(c) - Assembler
