The World Wide Web (WWW) is the newest route to travel through
the scattered information segments of the Internet, the network of
networks originally developed in 1969 by the U.S. Department of Defense for
communication in case of a nuclear attack. Through the years, the Internet
expanded and became a network connecting researchers in business and education.
However, maneuvering the massive information bases of the Internet remained
a problem for the general public who didn't have time to learn the complicated
commands needed to find information. As a result, accessing information via
the Internet did not gain popularity until the development of gopher menus
and the World Wide Web.
When Tim Berners-Lee and Robert Cailliau of the European Particle Physics
Laboratory proposed a system for organizing and documenting text, the menu-based
gopher had been under development and became the main way to tour
the Internet; however, the new system used hypertext instead of the gopher's
menu hierarchies.
Hypertext is text which contains "links" to other texts. By clicking
on a highlighted section of text with either a mouse or arrow keys, you are
taken to another document in another computer anywhere in the world. The second
document may also contain links to other documents. You don't need to know
where the referenced document is, and no command is necessary to display the
linked information. This structure allows information providers to connect
information in an infinite number of combinations from one document, unlike
the simple, tree-shaped hierarchy of the gopher menu system.
Although the WWW started in 1990, only the high-energy physics community
used the system. Then, in 1993 students at the University of Illinois designed
software, called Mosaic, which browsed, retrieved and interpreted documents
on the Web. The term browser now refers to programs like Mosaic that allow
you to navigate and view documents on the Web.
Yet hypertext isn't the only advantage of the World Wide Web. Depending
on your computer's capabilities and connection, you may be able to access
documents with audio, still graphics, and movies.
How to Access the World Wide Web
Users activate the WWW by a client called a browser. These browser are
either text- or graphic-based. Access is dependent on the connection you have.
Since it doesn't require any special software, the text-based (line-mode)
browsers such as Lynx allow a user with a basic computer and modem
to navigate the Web in text mode. Since it only deals with text, it ignores
big graphic files. As a result Lynx is popular as a high-speed way to access
the Web. Using hypertext, this browser allows you to click on a highlighted
word with the arrow and Enter keys. Lynx then automatically moves to that
document on the Internet.
Web documents using a graphic browser, such as Mosaic or Netscape Navigator,
look like pages from a book and thus are referred to as "pages." The text
usually has large titles and indented or bulleted items. In contrast, a text
browser shows letters in only one size. The graphic browser also provides
photographs or graphics in line with the text since these files are downloaded
with the text. In addition, compressed audio files and movie clips are available
with a graphic browser.
Getting Started
The best way to learn about the World Wide Web is to try it out for yourself.
Since this article was originally written in 1995, many changes have occurred
in the evolution of the web. Originally this article pointed to two search
engines, but with the explosion of competing search areas, it's necessary
to add a few more to this page. I have chosen my current favorite search engines/portals.
Each has strengths and weaknesses, but time and time again, they have provided
me with the information I've needed.
