This document defines the web and web tools, compares web 1.0 and 2.0, and provides examples. The web is a global network of internet sites that share resources via HTTP, as introduced by Tim Berners-Lee in 1989. Web 1.0 allowed one-way sharing of information from businesses to readers, while web 2.0 enables two-way social interactions and sharing through tools like social media and wikis. Examples include Britannica Online representing the static web 1.0 and Wikipedia embodying the collaborative web 2.0.
