Internet and the Web What is the Net? Internet Web WWW Online
Cyber Net Cloud Facebook ? Google ? Apps ?
Slide 4
4 Whats the Internet: Whats the Internet: : nuts and bolts view
Millions of connected computing devices: hosts, end- systems pcs
workstations, servers PDAs phones, toasters running network apps
communication links fiber, copper, radio, satellite routers:
forward packets (chunks) of data thru network Internet: network of
networks local ISP company network regional ISP router workstation
server mobile
Slide 5
5 A closer look at network structure: network edge:
applications and hosts network core: routers network of networks
access networks, physical media communication links
Slide 6
6 The Network Core Mesh of interconnected routers How is data
transferred through net? packet-switching: data sent thru net in
discrete chunks
Slide 7
7 The network edge: end systems (hosts): run application
programs e.g., WWW, email at edge of network client/server model
client host requests, receives service from server e.g., WWW client
(browser)/ server; email client/server peer-peer model: host
interaction symmetric e.g.: teleconferencing, torrent, napster
Slide 8
8 Internet protocol stack application: supporting network
applications FTP, SMTP, HTTP transport: host-host data transfer
TCP, UDP network: routing of data packets from source to
destination IP, routing protocols link: data transfer between
neighboring network elements PPP, ethernet physical: bits on the
wire application transport network link physical

layer software) The Web 9
Slide 10
WWW (Web) is A large-scale, on-line repository of information
that users can search using interactive application program called
a browser Interactive program that permits a user to view
multimedia information as a Web document, including hyperlinks to
other Web documents 10

Open Data on the Web 57 Open Data Anyone is free to use, reuse,
and redistribute Linked Open Data (LOD) Publishing and interlinking
structured data on the WWW http://linkeddata.org/
Slide 58
Linked Open Data Rating - Available on the web (whatever
format), but with an open licence - Available as machine-readable
structured data (e.g. excel instead of image scan of a table) -
Non-proprietary format (e.g. CSV instead of excel) - All the above
plus, Use open standards from W3C (RDF) to identify things - All
the above, plus: Link your data to other peoples data (Berners-Lee,
2010) 58
