Word scramble
Unscramble the letters and write each key term on the line.
1
MSERBELAS
A translator that converts an assembly language program into machine code, so the CPU can run it. Each mnemonic becomes one machine code instruction.
2
LTNTARAOSR
Software that converts high-level or assembly code into machine code, because the CPU can only run machine code. Types: assembler, compiler, interpreter.
3
XYATSN ORRRE
Code that breaks the rules of the language, like a missing bracket. The translator reports it and its line. A run-time error only occurs when the program runs.
4
MLPORCIE
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.
5
LUBEEEAXCT EIFL
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.
6
PROELCMI RORER PTEORR
A list of every error found after the compiler checks the whole program, with line numbers and error types. No executable is made and nothing runs until all are fixed.
7
EETRRRNPETI
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.
8
PSSTO TA RIFTS RRREO
An interpreter runs code line by line and halts at the first error it finds, reporting only that one. Earlier lines have already run. Later errors stay hidden until you fix it and run again.
9
IPCMOEDL APRROMG
A program translated all at once into an executable. It runs faster, needs no compiler to run, keeps the source code private, and gives a whole-program error report.
