Here's a couple of things that come to my mind.
1) What is IT? it's not just for Programming.
Go over the world of what people do in the working world of IT.
2) What is a OS?
Discuss the primary OSes and there benefits / downfalls ( start a in class flame war ) .
Microsoft - 90% market share of users and viruses.
Apple - Spendy, but less maintenance, designers use them to make Microsoft Ads.
Linux - Who? Runs Majority of super computers. Free.
** - Remember diversity is good.
3) Understanding client–server model.
"Hello World" and maybe some functions.
I haven't seen any good come out of this junk. Every time I want to watch something with some importance, I have to use Silverlight. I really get the feeling that the reason companies go with this tech is not because of application ubiquity, but because some jackass made a deal with Microsoft.
Just give me Netflix and I'll be happy!
