Compiler - Three from: ∞ Translates the whole program as a complete unit / at once ∞ Creates an executable file / object code ∞ A report / list of errors in the code is created ∞ Optimises the source code (to run efficiently) Interpreter - Three from: ∞ Translates a program one line of code at a time ∞ Machine code is directly executed // The interpreter is used each time the program / code is executed ∞ Will identify an error as soon as it finds one in a line of code
