While studying to get my CCNA, and start my new career in Networking, I took a notebook's worth of notes. I have never once, after getting the cert, reviewed them. Two years down the road, I've decided it's time to review them for accuracy/understanding, and then transcribe them here. This will help me index them faster, and it may help some other people who are just getting into networking to study too. Who knows. I'll tag those entries appropriately, so that they can be searched/indexed easily.
