A compiler and an interpreter are two different types of translator.

Mark scheme

Marking points from the official mark scheme (May/June 2022). The mark or mark type is shown in brackets.

1. [1] They both report/check for errors
2. [4] Four from (MAX 2 per translator): An interpreter translates the code line by line (and executes each line immediately) ... whereas a compiler translates the whole code at the same time (before executing it) A compiler produces an executable file ... but an interpreter does not An interpreter is required to run the code each time if used ... whereas a compiler is not An interpreter stops and reports an error as it is encountered ... whereas a compiler creates a report of all errors at the end of translation An interpreter will run code up to the point it finds an error ... whereas a compiler will not run the code at all if an error is found
