This document discusses the evolution of the internet and web technologies from the 1960s to present. It covers the development of the early internet (TCP/IP) and Web 1.0 (static HTML pages). It then summarizes key aspects of Web 2.0 technologies like blogs, wikis, social networking, podcasting, and mashups which enabled user-generated and dynamically updated content. The document also briefly introduces semantic web technologies like RDF, ontologies, and vocabularies which aim to make web data more machine-readable.
