  10. What is the Internet? • London Internet Exchange • Located in Docklands area in East London • Second large IX in Europe

  11. Malaysia and the Internet • Internet Usage Statistics:13,528,200 Internet users as of Sept/2006, 47.8% of the population, according to M.C.M.C. • Malaysia Internet Exchange (MyIX) • Established in November, 2003 • Launched on 15th December 2006 • 3 nodes connected in AIMS, NCC and TPM Jaring What is the Internet?

  25. Extranet application on global basis

  29. A standard method for exchanging and publishing information on the Internet. • Based on standard document formats such as HTML • Offers hyperlink • Supports a wide range of formatting • Can integrate graphics and animations • Make interactions possible • Benefits: • Easy to use • Provide a graphical environment • Standardization of tools and usages World Wide Web

  30. WWW-How it works Figure 3.7Information exchange between a web browser and web server

  31. E-mail Instant messaging (IM) and Internet Relay Chat (IRC) Usenet newsgroups FTP file transfer Telnet Blogs RSS (Really Simple Syndication) World Wide Web IPTV BitTorrent Internet tools

  32. An Internet standard for publishing and exchanging content using XML • Content can be published on a site that originates from another site • New method of distributing messages to subscribers Internet tools-RSS
