1. What is The Internet?

2. Internet Vs Intranet Internet –Computers connected throughout the world. PUBLIC Network Intranet- Secure connected computers within a business, school, or other organization. PRIVATE Network Connecting to a Network – Wireless, or Digital connections tie computers together

3. Origins of the Internet The Internet grew from military need. A network of connected computers shared defense information to all U.S. military bases around the world. The private network, called ARPNET, was created in the 1960s. Eventually, the idea of a worldwide network was used by non-military.

4. Internet Growth When computers became smaller and affordable to regular folks, there was an explosion in demand for internet service. The Internet YOU know, came to be in 1992, when Microsoft released a program called Internet Explorer that allowed people to get around the internet. The Internet was MUCH slower than it is today, but was navigated by using Hyperlinks, just like today.

5. Internet in the 1990s In the beginning, people mostly used AOL (America Online), an internet service provider (ISP) that gave access to the few places available. There was no google.com, no youtube.com, no Facebook.com (computers weren’t fast enough to handle these kinds of activities) The most popular sites were www.altavista.com (a search engine site), and www.napster.com, a site for downloading free musicwww.altavista.comwww.napster.com Mostly used for E-mail by the few public subscribers

6. Internet 2000-2011 This decade is known for the explosion in popularity of social networking sites Google is now the most influential company in technology. Every part of our lives are impacted by and accessible through internet technologies, (banking, entertainment, research, education, and general communication).

7. Internet (2011 and beyond) Emerging internet technologies are no longer confined to computers Cell phones are now smart phones Digital readers (Kindle, Nook, etc.) are slowly replacing traditional print books. The music industry has changed as the demand for CD’s (or other stored music formats) are being replaced with music downloads to mp3 players. Studies show that your generation, within 3-5 years, will be watching TV on line, MORE than watching TV on…TV.

8. Anatomy of a Web Address http://www.espn.com --- Part 1 http://www.espn.com The web address is broken down into a series of parts. http: represents Hypetext Protocol Language, that your computer can recognize---it is a basic software program that computers use to communicate with each other. www: represents the World Wide Web, this is the part of the Internet that is traditionally for CONSUMERS and the general public.

9. Anatomy of a Web Address http://www.espn.com --- Part 2 http://www.espn.com In this web address, this represents the “DOMAIN NAME”…this is traditionally the name of the host computer on the Internet. Domain names are proprietary, in that the first person to buy the domain name gets it. (example www.ua.edu is the University of Alabama –not Arkansas, Alaska, or Argentina  because Alabama bought it first). You could even buy your name---if no one has already www.ua.edu

10. Anatomy of a Web Address http://www.espn.com --- Part 3 http://www.espn.com The letters after the domain name are an EXTENSION of the domain that tells what kind of site it is:.com – a commercial entity that provides products or services for profit.edu – an educational entity (typically college/university).gov – a government entity.mil – military network for armed services.net – an entity that is a group of networked computers.org – a non-profit organization

11. Internet or NOT This is not an easy answer…IF the address has “www,” it is on the Internet. However, there is another component on the Internet that is NOT on the World Wide Web. This includes the military presence (Us and other); medical institutions, higher education, and some business sectors). We do not have access to many parts of the Internet (these are considered Intranet elements). Example – U.S. troop movements in Afghanistan would not be on line for you to see)
