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. The World Wide Web The World Wide Web is the part of the internet that is available to the public. If a site has “www” in the address, it is a public site on the World Wide Web. We do not have access to many parts of the Internet. Example – U.S. troop movements in Afghanistan would not be available to everyone on the World Wide Web, but authorized personnel can go through the internet to access the PRIVATE intranet site with that information.

4. 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.

5. 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.

6. 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, no YouTube, and no Facebook! Computers just weren’t fast enough to handle these kinds of activities. The most popular sites were www.altavista.com a search engine, and www.napster.com, a site for downloading free musicwww.altavista.comwww.napster.com The internet was mostly used for E-mail by the few public subscribers

7. Internet 2000-2010 The first decade of the 21 st century 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).

8. Internet (2011 and beyond) Emerging internet technologies are no longer confined to computers – cell phones are now smart phones. Cell technology has evolved to Tablets with PC connectivity Cloud storage makes sharing and collaborative production available to everyone. 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.

9. Anatomy of a Web Address Part 1 http://www.espn.com/games http://www.espn.com The Uniform Resource Locator (URL), or “web address,” is broken into many 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: indicates the site is on the World Wide Web, the part of the Internet that is accessible to the general public.

10. Anatomy of a Web Address Part 2 http://www.espn.com/games This part of the address represents the “DOMAIN NAME”…this is usually the name of the entity that operates or hosts the site on the Internet. Domain names are proprietary and unique and must be leased for an annual fee through a registrar, such as GoDaddy.com. Web Hosts, such as Google Sites, often provide free registration within their service.

11. Anatomy of a Web Address Part 3 http://www.espn.com/games 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. The.com sites that do not “sell” anything make their money by letting others advertise on their site in side-bars or pop-ups..edu – an educational entity (college/university).gov – a U.S. government entity such as the FBI, Whitehouse, IRS, etc.

12. Anatomy of a Web Address Part 3 http://www.espn.com/games http://www.espn.com.mil – The U.S. military network for Armed Forces.net – an entity that is a group of networked computers. These are often large, worldwide corporations..org – a non-profit organization, such as charities, churches, and public services There are numerous other site extensions throughout the world and most give some indication of the country of origin. For example, http://www.parliment.uk is the address for the government of the United Kingdom.www.parliment.uk

13. Everything that comes behind the domain extension directs you to a very specific location (or “page”) within that domain. Each “slash” directs you onward to sub-pages within the site. Anatomy of a Web Address Part 4 http://www.espn.com/games http://www.espn.com

14. A Final Note… The “slash” ( / ) is used to indicate sections within a URL The “back-slash” ( \ ) is used ONLY in directions, or “command strings,” when writing code or accessing strings of code in the operating system of a computer. …. But that’s another story!
