In the previous article, we met John Hancock who had just bought a new Dell
laptop from Circuit City. He also bought a wireless router and sat outside purchasing a new domain name from Godaddy.com. Enjoying the freedom of the wireless technology, John sat outside in his lounge chair and also purchased a place to host email and a new website he is going to build.
You might have noticed that John did look for the "HTTPS" instead of the "HTTP" when he made a secure transaction. This is a good thing! Kudos to John for remembering to do that. The extra "S" in the URL stands for "Secure" meaning he is making his transaction with a credit card over a secure site. This will prevent anyone else from seeing the credit card numbers on the website (Basically).
John also got a pretty good deal on the Dell laptop from Circuit City. The wireless router was not a bad price either. John can add a few more points to his "shopping karma". Godaddy.com also has some of the lowest prices around for domain registration. Way to go John!
Now, aside for saving money with those purchases, John actually did make some mistakes that could cost him in the long run. The mistakes were not due to the purchases he made. They were due to the technology he is using.
As convenient as wireless networking is, he was not aware of a few things. Namely, how insecure wireless technology can be.

Wireless networks have SO many conveniences to them. No cords to tangle up and tie you down, no running unsightly cables through walls, stairs, basements, floors or ceilings, and the ease of being able to move around - but at what cost? And, I do not mean monetary costs - or do I?
With so many reasons to want to go wireless with computers on a network, sometimes the most obvious reasons are overlooked. At what expense do people risk giving up the security of cables to go wireless? Sure, you can move around a room or floor, and you are not tied down by a cable, but the cable actually adds a layer of protection to your network.
For example, let’s say that John Hancock has a new Dell laptop he bought at Circuit City for $650.00 (on sale). It comes with a built in wireless B/G adapter in it. He buys a wireless router to go with it - at the suggestion of a co-worker. It cost John about $45.00. As one of the perks, he will be able to take his laptop out on the patio and surf the Internet, or anywhere in the house he feels like going - all with no cables to tie him down.
