DISCUSSION

How might the personalized web be detrimental to diversity and tolerance?

How might social media contribute to your own self-segregation and spiral of silence?

Where do you get your news? and how might it be filtered?

Implications of personalization

Defining Internet– three layers

1. The physical layer (the network's hardware and wires)

2. the logical layer (the protocols that determine who connects to what)

3. the content layer (the actual material delivered by the protocols over the wires

Lawrence Lessig, The Future of Ideas: The Fate of the Commons in a Connected World

1. The physical layer or infrastructure of new mediaTelephone systems/cable systemsInternet service providersComputer hardware (including routers,

modems)Mobile phonesComputer softwarePortals

gateway sites, search engines

2. The logical layer of new media

Protocols/languages/file formatsHTMLPHPMP3TCP/IP

3. Content layer

Text, images, video, software, etc.

Transformed old cultural formsweb radio, web TV, movies online, online

newspapers, web zines, itunes

Spanking new formsDigital games, blogs, tweets, re-tweets, status

updates, new video genres (remix, etc), memes

What is the Internet?

A set of standards for interconnecting networks “A network of networks”

intergalactic computer network”

1969 ARPANETprecursor to Internet

ARPANET 1971

Internet Timeline (cont)

1974 TCP (TCP/IP by 1978) Vint Cerf & Bob Kahn Enables packet switching IP – packets, TCP – connections broken and reassembled at incredible speeds, flawlessly

Principles of Internet Architecture:

distributed (no central control)end to end principle “stupid network”

Passing of packets are neutral (though some ISPs filter

open communication protocols (language)multilayered (layers isolated)compatibility between networks

“An open system of computer communication” –Castells

Internet Timeline (cont)

1983 ARPANET separates into MILNET and ARPA-INTERNET Domain Name System .edu, .gov, .com, .mil, .org, .net, .int

1984 NSF expands high speed network

1990 ARPANET decommissioned; The Internet is privatized ISPs create networks based on ARPANET’s design 1000s of ISPs cooperate with one another to create the Internet

Internet origins and values

ARPANET cooperation, openness, consensus

Shared protocolsAgreement on technical standardsDecentralized and distributed network Run by volunteersFor freeFor the public good

“The Internet cannot be regulated”Nicholas Negroponte in Being Digital (1995)

The Internet a volunteer baseddecentralized distributed network of networks

1998 ruling the root

ICANN - non profit, private corporation given authority by US Department of Commerce to

manage the Internet naming system1. Root server system management

2. IP address allocation

3. Domain name management (internet naming system)• top level domain (TLD)• country code top level domain (ccTLDs)

Root authority

Internet goes globalroot authority is challenged

Sell to highest bidder?put under US control?

Jon Postel (1943-1998)

documented and developed

key Internet standardsTCP/IP – basic Net protocolsSMTP – email transferDNS – name servers

ran the Internet naming & address system on a voluntary, free-of-charge, and public

interest basis

At 5:04pm on Jan 28th 1998 Jon Postel pulls the root! Jan 29th US Gov. and Network Solutions

secures root authorityOctober 16th 1998 Jon Postel dies (some say from stress over DNS root authority)
