Web 1.0 is getting information from the Web.

This is simply using the internet like a library. It does not take much skill and is a very passive activity whereby one simply gathers and manipulates other peoples information to suit your own need. Some examples included: Britannica Online, Personal Web Sites and Directories. Web 1.0 is something that cannot be added to and cannot be continuously constructed. 

Web 2.0 is constructing knowledge collaboratively on the Web.

This means that it is a contribution-type internet. People are expected not only to gather and gain information but also to contribute and to be creative to help and expand on what information is on the web. It is a collaborative place where you can make friends from all across the world in a very easy and stress free way. Examples of Web 2.0 are one the diagram below. Programs include Wiki’s, Blogs, Flickr, Google Earth and YouTube
