Word scramble
Unscramble the letters and write each key term on the line.
1
TNERETRREPI
Runs code line by line with no wait to compile, so unfinished programs can be tested at once. It stops at the faulty line, making errors easy to find. Source code runs on any machine with one.
2
EILN YB ELIN VYREE URN
An interpreter translates the source code again on every run, so programs run slower and need the interpreter and source code each time. Only one error is shown at a time.
3
OEOHSC A ROTLARANST
Pick an assembler for assembly code, an interpreter while testing a program, or a compiler for release to customers, then justify your choice using 'because'.
4
EDI
Integrated development environment: one program, such as IDLE, Thonny or Visual Studio, with the tools to write, run and test code. It is not a language or a translator.
5
DOEC OERTID
The part of an IDE where you type and edit source code. It shows line numbers and syntax highlighting (colour-coded keywords), which a plain text editor does not.
6
NIE-TRMU IENNNOMERVT
An IDE feature that lets you run your program and see it work, including its input and output, without leaving the IDE. It has a run button, a console and can step through code.
7
UTLIN-IB NATORARTSL
A compiler or interpreter built into an IDE, so the programmer can translate and run code from one button without needing separate translator software.
8
RORRE ICANSIDOGTS
An IDE tool that finds errors in code and tells the programmer where they are and what kind they are, using line numbers, error messages, highlighting and debugging tools.

1TNERETRREPI → interpreter — Runs code line by line with no wait to compile, so unfinished programs can be tested at once. It stops at the faulty line, making errors easy to find. Source code runs on any machine with one.
2EILN YB ELIN VYREE URN → line by line every run — An interpreter translates the source code again on every run, so programs run slower and need the interpreter and source code each time. Only one error is shown at a time.
3OEOHSC A ROTLARANST → choose a translator — Pick an assembler for assembly code, an interpreter while testing a program, or a compiler for release to customers, then justify your choice using 'because'.
