Networks, transaction processing, decision support and the automated systems that act on data.
These are the statements the Information Processes and Technology syllabus makes about Communication and Control Systems. 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.
Topologies, protocols and transmission media, and matching a network to an organisation's needs.
Real-time and batch processing, ACID properties, and what happens when a transaction fails mid-way.
Data, model and knowledge-based systems, and the limits of advice a system can give.
Sensors, actuators and feedback loops, and the fail-safe behaviour a control system needs.
Star, bus, ring and mesh, and the cabling, switching and wireless choices that follow.
Bandwidth, latency and compression, and how each constrains what a system can deliver.
Open and closed loops, set points and error correction, with industrial examples.
Mobile data, coverage and security, and the constraints that appear when a system leaves the building.
HSC Information Processes and Technology - Examination Shape is 100 marks in 180 minutes. Questions on Communication and Control Systems 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 Information Processes and Technology 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.
Communication and Control Systems is module 2 of 4 in Information Processes and Technology. Students routinely lose marks because a question spans two modules, so the neighbouring modules are worth reading next to this one.
Dux diagnoses Information Processes and Technology dot point by dot point, then writes questions in the shape this course marks. Written answers come back marked against the bands.
