Intro to IS

I've never known anything about the versions of the web, or anything like the IP. So I was surprised to learn that I had missed so much when I attended my first IS (infocomm studies) lesson in school today. I could imagine how blank my face was when my teacher explained all about the IP and the versions of the web. But, of course, it was extremely easy to understand it and I finally got what IP was all about, and the difference between web 1.0 and 2.0. Even for someone like me whose computer knowledge was nothing to sneeze at, the concept of the IP was easy to understand. The IP was the internet pretocol, and it came in the form of numbers. However, people found it hard to remember, and so, through a series of changes, it evolved into today's URL. The versions of the Web took a bit longer, which, the difference was, Web 1.0 only allowed the creator to add information into the website, and the public could only see, while Web 2.0 allowed the creator AND the public to add in information and help make the website more informative. It was complicated, but still, I somehow or another managed to understand it. (With countless silent sniggers from my friend, of course) I have to get the hang of it though, or I'll never hear the end of it from my friend. Gotta run. G'day! ;)
