OCR J277 2.5.1: Languages
The free BugBot lesson that teach this point, a robot to try it on, and the past-paper questions that test it.
What it covers
BugBot's processor cannot read Python. Nor can the one in your laptop. A processor understands only its own machine code: patterns of binary that mean things like "add these two numbers" or "jump to that instruction". Every program in every other language has to be translated into machine code before it can run. This lesson is about the kinds of language, and the programs that translate between them.
- High level and low level
- Assembly language
- Translators
- Which does BugBot use?

Or do it in the simulator, with tasks that mark themselves
