Understanding the Differences Between the Internet and the World Wide Web

The Internet and the World Wide Web (WWW) are often confused, yet they refer to distinct concepts. The Internet is the global network of connected computers and routers that enables data transmission via protocols like HTTP, HTTPS, and FTP. In contrast, the World Wide Web specifically refers to the system for accessing websites and web pages through browsers using HTTP. This presentation explores the evolution of the web from simple information-distribution sites (Web 1.0) to interactive user-generated content (Web 2.0) and the interconnected data of the Semantic Web (Web 3.0).
