-- USSR launches Sputnik, first artificial earth satellite. Why is this relevantThe start of global telecommunications. Satellites play an important role in transmitting all sorts of data today.
In response, US forms the Advanced Research Projects Agency (ARPA) within the Department of Defense (DoD) to establish US lead in science and technology applicable to the military.
history of internet
Packet-switching (PS) networks developed Why is this relevant?As we will see later the Internet relies on packets to transfer data.
The origin is military : for utmost security in transferring information of networks (no single outage point).
plan`s of arenet were published
Birth of internetFirst node at UCLA (Los Angeles) closely followed by nodes at Stanford Research Institute, UCSB (Santa Barbara) and U of Utah (4 Nodes).
-- People communicate over a network15 nodes (23 hosts) on ARPANET.
E-mail invented -- a program to send messages across a distributed network. Why is this relevant? E-mail is still the main way of inter-person communication on the Internet today.
We will study how to use and send E-mail shortly in this course.
You will make extensive use of E-mail for the rest of your life.
-- Computers can connect more freely and easilyFirst public demonstration of ARPANET between 40 machines.
Internetworking Working Group (INWG) created to address need for establishing agreed upon protocols. Why is this relevant? Telnet specification
Telnet is still a relevant means of inter-machine connection today.
Global Networking becomes a realityFirst international connections to the ARPANET: University College of London (England) and Royal Radar Establishment (Norway)
Ethernet outlined -- this how local networks are basically connected today.
Internet ideas started.
Gateway architecture sketched on back of envelope in hotel lobby in San Francisco. Gateways define how large networks (maybe of different architecture) can be connected together.
File Transfer protocol specified -- how computers send and receive data.
-- Packets become mode of transferTransmission Control Program (TCP) specified. Packet network Intercommunication -- the basis of Internet Communication.

ContFirst MUD (Multiuser Dungeon) -- interactive multiuser sites. Interactive adventure games, board games, rich and detailed databases.
ARPA establishes the Internet Configuration Control Board (ICCB).
Packet Radio Network (PRNET) experiment starts with ARPA funding. Most communications take place between mobile vans.
News Groups bornComputer Science Department research computer network established in USA.
USENET established using UUCP.
-- Things start to come togetherBITNET, the "Because It's Time NETwork" Started as a cooperative network at the City University of New York, with the first connection to Yale Provides electronic mail and listserv servers to distribute information, as well as file transfers
CSNET (Computer Science NETwork) established to provide networking services (specially E-mail) to university scientists with no access to ARPANET. CSNET later becomes known as the Computer and Science Network.
-- TCP/IP defines future communicationDCA and ARPA establishes the Transmission Control Protocol (TCP) and Internet Protocol (IP), as the protocol suite, commonly known as TCP/IP, for ARPANET.
Why is this relevant? Leads to one of the first definitions of an internet as a connected set of networks, specifically those using TCP/IP, and Internet as connected TCP/IP internets.

Modernisation BeginsCommercial Internet eXchange (CIX) Association, Inc. formed after NSF lifts restrictions on the commercial use of the Net.
Wide Area Information Servers (WAIS) Why is relevant? Provides a mechanism for indexing and accessing information on the Internet.
Large bodies of knowledge available: E-mail messages, text, electronic books, Usenet articles, computer code, image, graphics, sound files, databases etc..
These form the basis of the index of information we see on WWW today.
-- Friendly User Interface to WWW establishedGopher released by Paul Lindner and Mark P. McCahill from the U of Minnesota. Why is relevant? Text based, menu-driven interface to access internet resources.
No need to remember or even know complex computer command. User Friendly Interface (?).
