Project Management; Databases; Multimedia. You now have three out of the five major topics in the HSC IPT course under your belt - well done! That brings us to today's lesson, where we will be getting our first taste of the fourth topic: Communications Systems.

Actually, that's only half-true. As you know very well, we have been talking about communications systems from day one of the preliminary course, let alone the HSC course. So what's different this time around? As you should expect, we are going to go into far greater levels of detail and explore the transmitting & receiving process in terms of its specific technical details. After we're done with this topic, you'll never think about a 'simple' text message the same way again!

To begin with, you need to familiarise yourself with the following diagram. Much like the information system diagram you learnt about last year, you will find this 'communications system framework' diagram very helpful in distinguishing between and understanding the various components and operations of the communications systems that are functioning around you every day.


1. For each of the following instances of communication, identify the source, transmitter, medium, receiver and destination that form the communications system.
  • You receive a postcard in the mail from a family member overseas.
  • You watch a TV show.
  • You place an order at McDonald's.
  • The person taking your order at McDonald's requests for your meal to be made.
2. In your textbook, read through pages 76-86 and answer the questions in Exercise 3.1 and 3.2 (you may skip the "Learning Activities"). The large amount of work being assigned is due to your missing a lesson on Friday for your agriculture nursery excursion.

P.S. You have missed the topic for Debate D, as it slipped off the front page rather quickly. Here's a link - good luck to teams 1 and 8!
