- 2. Software that converts high-level or assembly code into machine code, because the CPU can only run machine code. Types: assembler, compiler, interpreter. (10)
- 5. A translator that converts a whole high-level language program into machine code in one go, before the program is run. The machine code can then run without the source code. (8)
- 7. Code that breaks the rules of the language, like a missing bracket. The translator reports it and its line. A run-time ______ only occurs when the program runs. Word 1 of: ______ _____ (6)
- 9. A ______ translated all at once into an executable. It runs faster, needs no compiler to run, keeps the source code private, and gives a whole-______ error report. Word 2 of: ________ _______ (7)
- 10. Word 1 of the term in 9 Across: ________ _______ (8)

- 1. A translator that translates a high-level program one line at a time and runs each line straight away. It makes no executable file, so the source code and ______ are needed on every run. (11)
- 3. A translator that converts an assembly language program into machine code, so the CPU can run it. Each mnemonic becomes one machine code instruction. (9)
- 4. An interpreter runs code line by line and halts at the ______ error it finds, reporting only that one. Earlier lines have already run. Later errors stay hidden until you fix it and run again. Word 3 of: stops at _____ _____ (5)
- 6. The machine code program a compiler produces. It runs without the compiler or source code, needs no re-translation, and works only on the type of machine it was made for. Word 1 of: __________ file (10)
- 8. Word 2 of the term in 7 Across: ______ _____ (5)

2TRANSLATOR — Software that converts high-level or assembly code into machine code, because the CPU can only run machine code. Types: assembler, compiler, interpreter.
5COMPILER — A translator that converts a whole high-level language program into machine code in one go, before the program is run. The machine code can then run without the source code.
7SYNTAX — Code that breaks the rules of the language, like a missing bracket. The translator reports it and its line. A run-time ______ only occurs when the program runs. Word 1 of: ______ _____
9PROGRAM — A ______ translated all at once into an executable. It runs faster, needs no compiler to run, keeps the source code private, and gives a whole-______ error report. Word 2 of: ________ _______
10COMPILED — Word 1 of the term in 9 Across: ________ _______
Down
1INTERPRETER — A translator that translates a high-level program one line at a time and runs each line straight away. It makes no executable file, so the source code and ______ are needed on every run.
3ASSEMBLER — A translator that converts an assembly language program into machine code, so the CPU can run it. Each mnemonic becomes one machine code instruction.
4FIRST — An interpreter runs code line by line and halts at the ______ error it finds, reporting only that one. Earlier lines have already run. Later errors stay hidden until you fix it and run again. Word 3 of: stops at _____ _____
6EXECUTABLE — The machine code program a compiler produces. It runs without the compiler or source code, needs no re-translation, and works only on the type of machine it was made for. Word 1 of: __________ file
8ERROR — Word 2 of the term in 7 Across: ______ _____
