  1. The Internet:Its Origin, Uses, and Services Unit 1: Orientation CGT I

  2. What is the Internet? • The Internet is made up of computers all over the world. These computers are connected to each other by phone lines or cables. • Not all computers are connected to the Internet. If your computer is connected to the Internet, it can help you get information from other computers, send messages to a friend who lives far away, or do lots of other fun things like hear a song or see a famous painting.

  3. What is the World Wide Web? • The WWW is part of the Internet. On the Web, bits of information are linked together to make things easier to find. • Imagine if all the books in the New York Public Library were thrown into a big pile, and you needed to find one book on George Washington. It might take you days to find the book! • This is how the Internet feels sometimes. There is a lot of information, but it’s hard to find.

  4. The Web makes this easier for us. Having the Web is like taking that huge pile of books, putting them in order, and putting up some nice signs that will tell you exactly where to go! That way, you can go right to the books about George Washington without wasting time. • The Web does this by creating links. Links are shortcuts to information.

  5. What is Internet Explorer?What is Firefox? • Internet Explorer, Netscape, and Firefox are browsers. A browser helps you to understand the information your computer finds for you on the Web.

  6. What do I need to have to use the Internet? • You will need a computer, of course! You computer will need to be connected to a modem. A modem is a small box that sits between your computer and the phone line coming to your house. • Once you have a computer and a modem, your family will need to find an Internet service provider (ISP). This is a company (AT&T, Comcast, etc) that will create an Internet address for you and help you connect to the Internet.

  7. What does http://www.abc123.org mean? • This is an Internet address. By reading the parts of the address, computers on the Internet know where the address is. • There are different types of web domains. These include .com, .edu, and .org. Can you think of others? • .com = company • .edu = educational institution • .org = non-profit organization

  8. Does the Internet have rules? • Yes– Netiquette!  These are manners and rules that should be followed when you’re online.
