This is a really wonderful blog. You allow for our ignorance--yes, I am pretty much in the dark about how all of this works--but not so much anymore. No one ever bothered to explain what all those acronyms mean. I turn on my PC and it works. If it doesn't I call my son. Now, though I have a better overall idea of the logic that allows my PC to connect to a network.
The only objection I have to your article is the bit about the dog. Leave the dog in the car :)
