In this lecture:• Development of the Internet.• Birth of the World Wide Web.• The Media and Online Entertainment• Internet and Society

What is the Internet?• “A diverse set of independent networks,

interlinked to provide its users with the appearance of a single, uniform network.”

• A mass medium incorporating elements of interpersonal, group, and mass communications.

Development of the Internet• How do we make incompatible computers talk

with each other?• How do we share information?• Can we maintain military communication after

nuclear war? (But this system was never built!)

Packet Switching• 1964: Paul Baran develops decentralized

computer network for Air Force.• Messages are broken into small data packets then

packets are sent independently across the network.

• Receiving computer reassembles message.• But Air Force doesn’t build this network.• Donald Davies proposes similar civilian network

for Britain. Also not built.

How Packet Switching Works

ARPAnet • Pentagon’s Advanced Research

Projects Agency• Networking incompatible

computers across the country• Went online in 1969, same

year as the moon landing

The Internet• TCP/IP—Transmission Control

Protocol/Internet Protocol How data are transmitted and how computers can locate each other.

• InternetInternetworking of networks.

Interpersonal Communicationon the Internet

• Electronic mail (e-mail)A message sent from one computer user to another across a network.

• Instant message (IM)An e-mail system that allows two or more users to chat with one another in real time.

Major Components of the Web• Uniform resource locator (URL)

The address of the content placed on the Web.• Hypertext transfer protocol (http)

The standard set of rules for sending Web content over the Internet.

• Hypertext markup language (HTML)The programming language used to describe the content on Web pages.

Key Web Principles• One address to take users to a document.• Everything should be accessible/linkable.• Any type of data should be available on any type

of computer.• The Web should be a tool for interaction, not just

publication.• No central control.
