Networking #1 - The internet and the web / WWW

Welcome to the networking Module!!

Here we're going to learn a bit of how networks in general work (and the internet in particulad)  it's history it's inner workings, and how to fix that router at home that keeps on failing (and how to fix it)

This ties in with the previous module, as we need a computer to do any sort of networking, and how the computer works affects how it behaves on the network.

The idea here is to have a bit of an introduction. There is not necessarily any sense or direction to this first post on the subject, just a throw around of several concepts so that you can start to get an idea of how everything is tied together, a "high level view" to start with, with some more specific bits of knowledge. It will all make better sense when we go into a more granular and systematic approach.
