The Internet
• A “network of networks”
• Origins:
– Kleinrock (1960s): click here
– ARPANET (1969): click here
• Domain name system (DNS)
– Maps numeric “IP” addresses to “domain” names
– 1982: HOSTS.TXT
– Now: distributed, hierarchical database
• Core protocols: TCP/IP

A Brief History of the WWW
CERN 1989
(Geneva European Laboratory for Particle Physics)
Initial Proposal
A common and consistent user interface
Incorporation of a wide range of technologies and document types
A “universal readership”
1990: first line browser
1992: a few browsers and 50 web sites
1993: Mosaic browser for X Windows at NCSA (UIUC), 500 web sites
Since 1994: more browsers, web sites, web servers, search engines

What makes up a website?
Three main components to every website:
1. Web server (always-on program listening
for requests from web browsers)
2. Web objects (text and binary documents)
3. Web browser
– Not really part of a website—or is it?
– If a tree falls in a forest but nobody is around
to hear it, does it make a sound?
