How computers represent and process information, and what that means for data quality.
These are the statements the Digital Technology Year 8 syllabus makes about Digital Systems and Data. Dux records each one against the questions you answer, so you can see which of them you have actually been tested on and which have never been asked.

Year 8 Assessment Task Shape is 50 marks in 75 minutes. Questions on Digital Systems and Data are not one shape repeated: the command word decides what the marker is looking for, and the mark value decides how much of it. These are the ones Digital Technology Year 8 uses.
Dux writes practice for this module in exactly these shapes, so the drill is the same task the paper sets — not a general knowledge quiz with the module name on it.
Digital Systems and Data opens the Digital Technology Year 8 course. Students routinely lose marks because a question spans two modules, so the neighbouring modules are worth reading next to this one.
Dux diagnoses Digital Technology Year 8 dot point by dot point, then writes questions in the shape this course marks. Written answers come back marked against the bands.
