3. Internet and the Web What is the Net? Internet Web WWW Online Cyber Net Cloud Facebook ? Google ? Apps ?

4. 4 What’s the Internet: What’s the Internet: : “nuts and bolts” view Millions of connected computing devices: hosts, end- systems ◦ pc’s workstations, servers ◦ PDA’s 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

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

6. 6 The Network Core Mesh of interconnected routers How is data transferred through net? ◦ packet-switching: data sent thru net in discrete “chunks”

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

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

9.  runs on the Internet  An Internet application (an application layer software) The Web 9

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

11. World Wide Web (WWW) An Application that runs on the Internet A Global network of web documents ◦ Web Documents (HTML) ◦ Located by URLs ◦ Hyperlinks Inventor of the Web ◦ Sir Tim Berners-Lee (1990) (but Internet dates back to 1960’s) 11

56. Information Sharing ◦ Information publishing ◦ Understandable meaning ◦ Information dissemination Shared information ◦ Better utilization  Increased value Shared information put together ◦ Valuable knowledge 56

57. 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/

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 people’s data (Berners-Lee, 2010) ★ ★★ ★★★ ★★★★ ★★★★★ 58
