Internet and Web internet: network of interconnected networks. “Traffic” on the network follows agreed upon rules to keep the flow going. o IP (internet protocol) for addressing | *ping www.cnn.com | *public and private addressing in briefwww.cnn.com o DNS (Doman Name System) names to numbers, a phonebook web: a global set of documents connected by hyperlinks using the hypertext transfer protocol ( HTTP )|a “service” that runs on the internet. There are many other services that use the internet. Ex. E- mail, DHCP o PC: open command window; at *command prompt, type: ipconfig, the ipconfig /all, ipconfig /release, ipconfig /renew Protocols use ports | 0 to 65535 | HTTP 80

Do Not Track – StanfordDo Not Track Should government step in? o Consumers don’t know that information is being collected o The danger of data being combined… “ever-growing database” o Competition among advertising platforms may not result in optimal provision of privacy

9. Filtering: Not just Adds… Filters that show the internet the way we want to see it, including the news Ex. Google, NY Times, Washington Post Experiment: Search for “Egypt” Facebook: Relevance to you! “When the result is that our favorite pizza parlor shows up first when we Google pizza, it’s useful. But when the result is that we only see the information that is aligned with our religious or social or political beliefs, it’s difficult to maintain perspective.” ---Eli Pariser, Board President and former Executive Director of MoveOn.org
