NSW HSC Information Processes & Technology -- Core topic 3: Communications systems

[gdt]

Just read the syllabus and it is rubbish, absolute rubbish. There's only a limited time in a high school school room. It shouldn't be spent teaching outdated irrelevancies. Here's a partial list:

Simplex, half duplex, full duplex. Synchronous and asynchronous. Error checking, including parity, checksums and CRCs. Star, bus and ring topologies. Network administration tasks, such as client installation and adding users. A/D, D/A conversions.

This stuff was written in an era of PSTN modem communications and when networking software was an add-on to operating systems rather than being an essential part of the OS.
