- 5. Do You Ever Heard This ? • VICTORIAN INTERNET – What Was the “Victorian Internet” • The Telegraph • Invented in the 1840s. • Signals sent over wires that were established over vast distances • Used extensively by the U.S. Government during the American Civil War, 1861 - 1865 • Morse Code was dots and dashes, or short signals and long signals • The electronic signal standard of +/- 15 v. is still used in network interface cards today. Introduction
- 6. What Is Internet? • Internet can be defined as: – A network of networks, joining many government, university and private computers together and providing an infrastructure for the use of E-mail, bulletin boards, file archives, hypertext documents, databases and other computational resources – The vast collection of computer networks which form and act as a single huge network for transport of data and messages across distances which can be anywhere from the same office to anywhere in the world. – The largest network of networks in the world. – Uses TCP/IP protocols and packet switching . – Runs on any communications substrate. Introduction
- 7. What Can I Do On The Internet ? • Get Information • Send and receive email and chat • Join discussion groups and message boards • Get or exchange software and files • Explore the World Wide Web • Publish your own material on the web Introduction
- 8. What Can I Do On The Internet ? Introduction
- 9. Who Owns The Internet? • No organization, corporation, or government owns or runs the Internet. • Organizations work together to oversee and standardize what happens on the internet • The equipment, the computers, cables, routers, and so on, are owned by government and private organizations. Introduction
- 10. Does The Internet Create Immediately? • Other inventions in our history had to happen in order for the Internet to be created. – Telegraph – Radio – Telephone – Television Introduction No !!!
- 11. History of the Internet • Brief History of the Internet – 1968 - DARPA (Defense Advanced Research Projects Agency) contracts with BBN (Bolt, Beranek & Newman) to create ARPAnet – 1970 - First five nodes: UCLA, Stanford, UC Santa Barbara, U of Utah, and BBN – 1974 - TCP specification by Vint Cerf – 1984 – On January 1, the Internet with its 1000 hosts converts en masse to using TCP/IP for its messaging InternetHistory
- 12. A Brief History of the Internet: The Precursors I “Computers,” so to speak, have been around for thousands of years. So have networks (social networks, that is). It‟s only recently that they have come together so forcefully, altering social life as we knew it basically overnight. From the earliest abacus to the jacquard loom that led to punch card technology, computers that became permanently networked emerged in the 1960s. (click here for interactive abacus) InternetHistory
- 13. A Brief History of the Internet: The Precursors II Computers were an integral part of World War II. Their adoption as military technology created the first steps into computer networking, creating the first pattern of the Internet in the late 1960s. Technology development and the dependence on computers in both academic and business institutions in the 1980s increased public awareness and access to computers generally 1991, when Tim Berners-Lee introduced HTML, the World Wide Web (WWW), and Mosaic (which became Netscape Navigator). InternetHistory
- 14. 1958: ARPA, the Advanced Research Projects Agency, is created by the U.S. Defense Department in response to the 1957 Sputnik launch. 1962: IPTO, the Information processing Techniques Office, a branch of ARPA, creates the ARPANET under the leadership of Joseph Licklider (MIT), a minor program designed to stimulate research in interactive computing. A Brief History of the Internet: The Timeline InternetHistory
- 15. 1969: The ARPANET utilizes “packet switching” technology developed in part by Paul Baran of the RAND Corporation. The first 5 nodes in the network link UCLA, UCSB, Stanford, and Univ. of Utah and BBN 1972-4: The network expands to 15 nodes, and standardization of communication protocols ensues – TCP, or “transmission control protocol”, is developed and by 1978 the IP (inter-networking protocol) is added by Vint Cerf of Stanford, creating the network standard used today, TCP/IP. In 1974, the UNIX operating system is released by Bell labs, and set widely at universities. This begins the open source movement”. A Brief History of the Internet InternetHistory
- 16. 1977-78: U. Chicago students Christensen and Suess create MODEM software, and in 1978 they create the Computer Bulletin Board System (BBS), modeled after office bulletin boards used for public messaging. 1981-83: From the first BBS idea sprouted the USENET, a message system for the ARPA network, IBMs version, BITNET, used widely on college campuses and a private BBS, FIDONET (Tom Jennings), still widely used today (with 3 million subscribers). A Brief History of the Internet InternetHistory
- 17. 1983-88: MILNET, the military branch of the internet, splits off from ARPA-INTERNET for security purposes. In 1984, the National Science Foundation starts NSFNET, and by 1990 it replaces the obsolete ARPANET using the same “backbone” infrastructure. 1990: The Internet goes private, with a number of Internet Service Providers (ISPs) being created by business enterprises, most notably AOL (America Online). A Brief History of the Internet InternetHistory
- 18. 1991: Working at CERN, a high-energy physics lab in Switzerland, Tim Berners-Lee creates the World Wide Web, which utilizes - Hypertext Markup Language (html), - Hypertext Transport Protocol (http), and - URLs (Uniform Resource Locators). 1993- : MOSAIC, the first “web browser”, is created at the Univ. of Illinois, which later becomes Netscape Navigator. Microsoft enters the market late in 1995 with their Internet Explorer browser. A Brief History of the Internet InternetHistory

- 21. Internet Evolution • From Simple, But Significant Ideas Bigger Ones Grow 1940s to 1969 1945 1969 We can access information using electronic computers We do it reliably with “bits”, sending and receiving data We can do it cheaply by using Digital circuits etched in silicon. We can accomplish a lot by having a vast network of computers to use for accessing information and exchanging ideas We will prove that packet switching works over a WAN. Packet switching can be used to send digitized data though computer networks Hypertext can be used to allow rapid access to text data InternetEvolution

Internet Evolution • From Simple, But Significant Ideas Bigger Ones Grow 1970s to 1995 1970 1995 Ideas from 1940s to 1969 We need a protocol for Efficient and Reliable transmission of Packets over a WAN: TCP/IP The ARPANET needs to convert to a standard protocol and be renamed to The Internet Computers connected via the Internet can be used more easily if hypertext links are enabled using HTML and URLs: it‟s called World Wide Web The World Wide Web is easier to use if we have a browser that To browser web pages, running in a graphical user interface context. Great efficiencies can be accomplished if we use The Internet and the World Wide Web to conduct business. InternetEvolution
