After completing this chapter, you will be able to:

  • Define the Internet, describe how large it is, and find out how fast it is growing.

  • Know when you are really "on" the Internet.

  • List and define the eight basic Internet services of e-mail, listserv, newsgroups, chat, FTP, telnet, Gopher, and the World Wide Web.

  • Explain what is meant by client-server computing.

  • Understand the Internet naming system of domains and subdomains.

  • Provide a brief history of the Internet, explaining how it grew from its humble origins into the worldwide network that we enjoy today.

What is the Internet?

The Internet is composed of computers, all makes and models; connections such as phone lines, satellite links, digital datalines; and a common language--TCP/IP allows different computers to talk, understand and share information. It is the largest network in the world with computers in almost every country of the world.

What is the World Wide Web?

Also called "The Web," "W3," and "WWW," the World Wide Web is a global collection of multimedia documents that reside on the Internet. Web pages or documents contain links to other pages, forms to fill out, programs to be downloaded, sound files, movies and more. This system is woven around the world with hypertext and an addressing system as the glue holding it all together.

  • Hypertext - allows the user to go to related information in the same or another database
  • Address (location/URL) - identifies the location of a file. Makes linkage from one item to another possible.
  • Browser - Software on your computer that retrieves and displays Web information for you.

Everything You Wanted to Know About Hypertext....But Were Afraid to Ask

Hypertext is a type of content that forms links to other content. Usually hypertext can be identified as underlined, colored text. Behind that colored text an Internet address is invisibly embedded so that if you click on it, the document at that address will be displayed on your screen.

Knowing all the screen indicators (cursor becoming a hand, address showing at the bottom of the browser screen) are becoming increasingly important because the look and design of a Web page are often as important as content to those doing the development. As such, graphics, icons and blocks of what looks like just plain text can actually be hypertext. So, you may not have any other visual cue than the mouse pointer turning into a hand. For an example, move the cursor over text in the navigational bar on the left hand side of this page. Can you find the hypertext links?

Root Domains

Knowing something about root domains is a good starting point for dissecting URLs or web addresses. The collection of networks making up the Internet is divided into groups called domains. The domains represent either a type of organization or a geographical location. For example, a site domain ending in .edu indicates an educational institution, .com, a commercial enterprise, .gov, a U.S. government body, .mi., U.S. military, .net, networks, .org, a nonprofit organization.
Examples:
DomainType of OrganizationExample
.comCommercial organizationswww.microsoft.com
.eduEducational institutionswww.monterey.edu
.govU.S. governmentirs.ustreas.gov
.milU.S. militarynps.navy.mil
.netNetworkswww.mbay.net
.orgNonprofit organizationswww.igc.org

Geographic Names

The geographical names representing a country or state are two letters long. For examples, take a look at FAQ: International Email Accessibility
