Another way to move around through sites on the Internet
is to use hot links. Hot links are electronic cross-references;
they are specially designated words or images that, when
selected, will take your Web browser to a new Web site
or to a different page of the current site. Links appear
in almost every Web site. By using them, you can quickly
and easily move to new relevant destinations on the Internet.
They often appear as highlighted or underlined words or
As you travel through the Internet
and follow links to various new sites, you can retrace
your steps if you want to return to a site. Use the
"Back" and "Forward" buttons on
your Web browser's toolbar to page through the sites
Using Search Engines
If you don't know the address of a
certain Web site, or want to find a list of sites relevant
to a certain topic, you can use a search engine. A search
engine is like a card catalog for all the Web sites
on the Internet. Different companies have developed
different search engines, such as Alta Vista, Excite,
Yahoo, Infoseek, and HotBot. Each search engine offers
different features, but they all basically work the
To use a search engine, you must get
to its Web site. Type the address of the search engine
into your Web browser. (All the search engine's addresses
are similar and easy to remember; they are all in the
same format: http://www.hotbot.com, http://www.altavista.com,
etc.) At the search engine's Web site, type in a specific
topic (like American History) and click the "Search"
or "Find" button on the screen. A list of
links will then appear in order of their relevancy.
Click on a link to be transported to its Web site. If
you don't find what you are looking for using one search
engine, you may be able to find it with one of the others.
Keeping Track of Where You've Been
Sometimes you'll find it impossible
to keep track of where you've been or what your favorite
sites are. As already described, you can use your browser's
"Back" and "Forward" buttons to
page through the sites you've visited. Netscape Navigator
and Internet Explorer also have a tool called the Go
menu, which lists the recent sites you've been to.
Pull down the menu (which will be in the toolbar or
under a triangle to the right of the "Back"
button) and highlight the address you want to revisit.
With the Go menu, you do not have to page through every
visited site consecutively.
If you need to recall a site you have
visited in a previous session, or if you want to verify
a student's work, you can open the History folder.
This displays a broad history of Web site searches.
Finally, if you find a site that you
know you will want to revisit, you can bookmark
it. When you are at your selected Web site, highlight
"Make Bookmark" in one of the toolbar menus.
(The name of the menu this command is in varies depending
on which Web browser you're using; it may be "Bookmarks,"
or "Favorites" or something similar.) This
will save the site's address and title in a list of
your favorite sites. You can also change the title by
which the site is saved on your computer. In the future,
you can move directly to a bookmarked site by selecting
it from your list of bookmarks.
As you explore various Web sites, you
may be asked to download certain plug-ins. Plug-ins,
also known as "helper applications," are software
programs that permit access to certain Web sites or
allow you to download and use specific types of files.
Often, these are multimedia files, which, for example,
play sounds (such as files whose names end with .wav
or .ra) or show movies (such as files ending with .avi,
.mov, or .mpeg). Plug-ins are usually free. Check with
your network administrator or Internet Service Provider
about plug-ins that may already exist on your computer's
