<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal" style="margin-bottom:12.0pt"><br>
Hi all. One question that has come to mind recently while going through VCAA, CSE, VITTA and other SD exams is how deeply we should be covering key knowledge like...<br>
<br>
- SD U3O1 KK03 - a brief overview of the concept of the OSI model for network protocols<br>
- SD U4O2 KK01- technical underpinnings of intranets, the Internet and virtual private networks<br>
- SD U4O2 KK02- characteristics of wired and wireless networks<br clear="all">
<br>
My kids have had no more exposure to the OSI than along the lines of, "These are the OSI stages, and these a few of the main things that happen in each stage. Data to be transmitted passes through these stages like a car being methodically stripped down to
its parts, shipped overseas, and then reassembled again. This is what the physical layer does." I don't expect them to memorise the protocols that operate at each level.
<br>
<br>
For wired/wireless communication, I don't go much beyond covering the relative strengths, weaknesses and capabilities of CAT, FOC, WiFi ("Code-named 802.11 with 4 different flavours"), microwave, and infrared.<br>
I don't drill down into fine technical detail. Do you do more on OSI and networking technology than this? I'd be keen to hear.
<br>
<br>
Some questions I have seen make me wonder: I feel that they are too deep and specific for the specified key knowledge, especially when only a "brief overview" is asked for, and the only named OSI level is the physical level.<br>
I don't want to criticise authors, but I have seen questions like...<br>
<br>
- At what level of the OSI does HTTP operate?<br>
- Why would Telnet not be a good idea for secure remote access?<br>
- Which of the 802.11 protocols are compatible with each other?<br>
- What's the difference between bridges, routers, switches etc with reference to the OSI model<br>
<br>
I would find it hard to justify the time needed for such exhaustive coverage of these topics, and since the VCAA exams have not examined students in such technical detail, I doubt it's really useful.<br>
<br>
How far do you go covering the technicalities of the technologies?<br>
