article or a book inserts a footnote symbol, we scan the bottom of the page and are
possibly directed to another page or book. Authors of Internet computer documents
can do essentially the same thing using a technique that will underline or highlight a
word, a phrase, or an image in their document.
The highlighted word or image is a clue to the reader that an associated Internet
resource, often another document, exists. This Internet document can be fetched and
displayed immediately for the reader. The document may even be on a different
computer and located in another country. David Peal, author of Access the Internet,
notes that this technique «links you to actual documents, not just references to them»
The Web also supports the storage and retrieval, or playing, of photographs,
graphics, animations, videos, and sounds. Loma, the housewife mentioned at the
outset of the previous artic le, obtained and played a short color movie of the current
theories regarding the universe. She heard the narration through her computer's audio
system.
Surfing the Net
By using a Web browser, a person can easily and quickly view information and
colorful graphics that may be stored on computers in many different countries. Using
a Web browser can be similar in some ways to actual travel, only easier. One can
visit the Web exhibits of the Dead Sea Scrolls or the Holocaust Memorial Museum.
This ability to move nimbly back and forth from one Internet Web site to another is
commonly called surfing the Net.
Businesses and other organizations have become interested in the Web as a
means to advertise their products or services as well as to offer other kinds of
information. They create a Web page, a sort of electronic storefront window. Once an
organization's Web page address is known, potential customers can use a browser to
go «shopping», or information browsing. As in any marketplace, however, not all
products, services, or information provided on the Internet are wholesome.
Researchers are trying to make the Internet secure enough for confidential and
safeguarded transactions. Another worldwide Internet-dubbed by some Internet II – is
being developed because of the increased traffic that this commercial activity has
generated.
What Is «Chat»?
Another common service of the Internet is the Internet Relay Chat, or Chat. Chat
allows a group of people, using aliases, to send messages to one another immediately.
While used by a variety of age groups, it is especially popular among young people.
Once connected, the user is brought into contact with a large number of other users
from all around the world.
So-called chat rooms, or chat channels, are created that feature a particular
theme, such as science fiction, movies, sports, or romance. All the messages typed
within a chat room appear almost simultaneous ly on the computer screens of all
participants for that chat room.
