Unit 7: The Internet and the World Wide Web
This unit explores the Internet, the global network of computers that has revolutionized communication and reshaped modern society. We will trace its history from a government research project to the commercial powerhouse it is today.
We will examine the fundamental technologies and protocols that make the internet work, including TCP/IP, IP addresses, and the Domain Name System (DNS). We will then look at the most popular service that runs on the internet: the World Wide Web, and the protocols like HTTP that power it. Finally, we will discuss the enormous impact of the internet, from e-commerce and e-governance to the critical social issues of privacy and the digital divide.
