 What is the Internet?  How it Started  Important events

 The Internet (or internet ) is a global system of interconnected computer networks that use the standard Internet protocol suite ( TCP/IP ) to serve billions of users worldwide. It is a network of networks that consists of millions of private, public, academic, business, and government networks, of local to global scope, that are linked by a broad array of electronic, wireless and optical networking technologies.

 The formation of the Internet was the heating up of the Cold War. The Soviet Union's launch of the Sputnik satellite spurred the U.S. Defense Department to consider ways information could still be disseminated even after a nuclear attack. This eventually led to the formation of the ARPANET (Advanced Research Projects Agency Network), the network that ultimately evolved into what we now know as the Internet.

 1969-Arpanet was born  was developed  1973-The first transatlantic connection on Arpanet  1974-Transmission Control Protocol for Arpanet was proposed  1975-The first client, MSG, was created  1980-CERN launched ENQUIRE (hypertext and hyperlinks)  Arpanet switched over to Transmission Control Protocol  1984-The Domain Name System was created  1986-Protocol Wars began (OSI vs. Arpanet)  1989-America Online (AOL) was created  1989-The proposal for the World Wide Web was made  1990-Arpanet ceased to exist  The first web page was created

 1995-The Internet was first commercialised  1996-The first web-based service (hotmail) was created  1998-Google beta was created  2000-The year of the dotcom collapse  2001-Wikipedia was launched  2003-Skype is released to the public  2004-Social media was created  2004-Facebook was opened to college students  2005-Youtube was launched  2006-Twitter was launched  2007-The iPhone was created

 computers at Stanford and UCLA connected for the first time. In effect, they were the first hosts on what would one day become the Internet.  Arpanet made its first trans-Atlantic connection in 1973, with the University College of London  A proposal was published to link Arpa- like networks together into a so-called "inter- network", which would have no central control and would work around a transmission control protocol

 the first PC modem, developed by Dennis Hayes and Dale Heatherington, was introduced and initially sold to computer hobbyists.  Arpanet computers to switched over to the TCP/IP protocols developed by Vinton Cerf. A few hundred computers were affected by the switch. The name server was also developed in ’83.  The domain name system was created. The domain name system was important in that it made addresses on the Internet more human- friendly compared to its numerical IP address counterparts. DNS servers allowed Internet users to type in an easy-to-remember domain name and then converted it to the IP address automatically.

 There were nearly 30,000 hosts on the Internet. The original Arpanet protocol had been limited to 1,000 hosts, but the adoption of the TCP/IP standard made larger numbers of hosts possible.  The code for the World Wide Web was written by Tim Berners-Lee, based on his proposal from the year before, along with the standards for HTML, HTTP, and URLs  The first web page was created  The first widely downloaded Internet browser, Mosaic, was released  the web became commercialized SSL (Secure Sockets Layer) encryption was developed by Netscape, making it safer to conduct financial transactions (like credit card payments) online.

 HoTMaiL, the first webmail service, was launched.  Google went live, revolutionizing the way in which people find information online.  Social media–sites and web applications that allow its users to create and share content and to connect with one another–started around this period.  the iPhone was created, which was almost wholly responsible for renewed interest in mobile web applications and design.
