Internet

To begin our discussion of Internet, it is important that we understand exactly what this animal really is. The Internet is made up of all of the program ellements which allow computers to talk and exchange information with each other. Although there are lots of parts that make up the Internet, the primary ones we are most interested in are the WorldWide Web (www) and E-Mail.

The World Wide Web (known as "the web")is a part of the Internet "designed to allow easier navigation through the use of graphical user interfaces and hypertext links between different addresses." That's a fancy way of saying that the WorldWide Web is a system that allows you to travel the Internet super highway by simply entering the destination address and hyitting "Enter." It's as close to Star Trek's transporter beam as we're ever going to get!

Pages on the web are designed using a special programming language known as Hypertext Markup Language (HTML). Each page has its own specific address. Entering a page's address allows you to jump directly to that page. Addresses on the web are as specific as addresses on an envelope. The address is constucted using the following three parts seperated by periods (referred to as "dots"):

  1. the part of the Internet the site is on (in most casses, the WorldWide Web)
  2. the name of the site (normally, the entity's name, i.e. Sears)
  3. what the company does for a living
    1. com - commercial (sells you something)
    2. org - non-profit organization
    3. edu - educational
    4. gov - governmental
    5. net - network of computers
    6. mil - military
    7. the two letters of the country the site is in
