Navigating the Web
In Lesson 3, "Introduction to the World Wide
Web," you learned a lot about how the Web works. As you read on, you put the Web on
the back burner to become familiar with some of the great things the Internet has to
offer. But now you're ready to meet the most interactive and dynamic part of the Net head
on.
In this lesson, you find the answers to the
following questions:
- How can I deal with so much information on the Web?
- How do I navigate around the Web?
- What are all those buttons for on my browser?
- Can I keep track of where I've been?
- How do I keep a permanent record of my favorite
sites?
Whether you use Netscape Navigator or Internet
Explorer, most of the information in this lesson applies. I give examples for both
browsers. For more detailed information on these two browsers, refer to Lesson 14,
"Netscape Versus Internet Explorer: Finding the Right Browser."
Coping with Information Overload
Experienced Internet users are constantly inundated
with complaints about how useless the Internet has become because too much information is
available. When one Web site can index over 50 million Web pages, you obviously can find a
lot of information.
But think about this fact for a moment. Is this
really anything new? Have you ever been to a major city or university library? Could you
handle all the information in all the guides in even one of these libraries? Probably not.
In a real sense, the Web is no different. A great
deal of information is available, yes. But, like in many of the libraries you visit, tools
are available to help you find what you need. Also, though it may not look like it at
first, the Web does have an organization that enables you to span vast distances of
resources in a short period of time.
Time Saver: Don't panic. These words made
famous by Douglas Adams in The Hitchhiker's Guide series are applicable here. Perhaps the
biggest key to conquering the Internet and the Web is simply to remain calm. If you like,
you can even take a towel!
Before you learn about some of the actual tools
you'll use to find your way around, think about how many people are able to go into a
large library without getting overwhelmed; then apply those principles to the Web. By
doing so, you can have a set of mental tools to keep in mind as you tackle the tangled
Web.
- Familiarity breeds...well, familiarity. No one has
ever gone into a library for the first time and been comfortable. You need to walk around
some, find out where different types of guides are located--get to know the place. Apply
this rule to the Web. Surf around some; just look around to get a feel for where things
are located and get a feel for what it's like.
- The right tools are invaluable. Just as you'd never
try to keep the locations of six different library guides in your head, don't try to do too
much on the Web either. Use your browser's History and guidemark features (which I describe
later in this lesson) to help you. The Web is a big place, so don't be afraid to write
things down either.
- Go ahead and ask questions. Take advantage of what
you've learned about newsgroups and e-mail to get information about the Web. Friends,
professionals, and others who are accessible electronically make up a great team of
Internet "reference librarians."
- A card catalog is the best tool to help you find
information in the library. Internet search engines, covered in Lesson 16, "Searching
the Web for Virtually Anything," are a must-have on the Internet. You will find
yourself searching the Web a lot to locate only that information you're interested in.
Exploring Navigation Basics
You must be familiar with several basics to start
exploring the Web. You must understand how individual pages on the Web can be viewed and
explored, you need to know how hyperlinks work, and you need to be familiar with browser
toolbar buttons. Once you're familiar with these important parts of the Web, you're well
on your way to becoming an experienced Web user.
Navigating Web Pages
If navigating an individual Web page seems simple
and obvious to you, you might want to skip to the next section. You might be surprised,
however, at the number of beginners who fail to realize how to get around on a Web page.
The key is in realizing that any particular Web page
can be as long or as short as the Webmaster programs it to be. Many people, when they get
on the Web for the first time, think that what appears on their screen is all there is.
The page in Figure 13.1, for example, contains a lot of text, links and
"action," but you should notice one thing right away. Note that both the
horizontal and vertical scroll bars are active, which tells you that this page is wider
and longer than will fit in the screen.
Figure 13.1.
You can probably tell that there's more than
meets the eye on this Web page.
Time Saver: Maximizing your browser window to
take up your entire monitor is always a good idea. This way, you can ensure that you view
the most possible information. The only time this may not be true is if you have a large
(17-inch or bigger) monitor, in which case adjusting your browser to take up a half screen
should be fine.
Unless the specific piece of information you want is
at the very top of a page, you should make a habit of scrolling down a Web page when you
first encounter it. By doing so, you know how much and what type of information is on the
page you're looking at.
Following That Link
The simplest and most useful tool on the Web is the
hyperlink. This underlined and colored word can take you to a page next door or halfway
around the world. The hyperlink is the key to the nonlinear nature of the Web.
The hyperlink also is the reason that the Web is so
easy to use. With a quick glance, you know immediately where you can go from any page. The
page shown in Figure 13.2 (http://www.shareware.com), for example, has text links
to New Arrivals, Search, Bag the beta, and more. Because these
words look different from other words on the page, you know you can click them to go to
another page.
Figure 13.2.
Text hyperlinks are easy to see and follow on the
Web.
Not all hyperlinks are so obvious, however. Often,
Webmasters create graphics that are themselves hyperlinks. Obvious graphical hyperlinks
have colored borders around them so that you know they are hyperlinks.
Webmasters are more commonly putting graphical
hyperlinks on their pages now to create a more realistic feel to them. If you look again
at the page in Figure 13.2, you will see a chair in the bottom-right corner. Even though
it doesn't have a border around it, the chair is a link, too.
Time Saver: When you're trying to find links
on a page with a lot of graphics, pay special attention to your cursor. Whenever it passes
over a link on a page, it turns from a cursor into a hand. When your cursor becomes a
hand, you know you're looking at a hyperlink.
You also should know about one last type of
graphical hyperlink: the image map. An image map is a special type of graphic that takes
you to different pages depending on where on the graphic you click. If you see a graphic
with a row of guides, for example, you might go to a different page depending on which guide
your cursor is over when you click.
Using Toolbar Buttons
You need to do more than simply click links to go
from one place to another. You need another set of tools to help you. Most major browsers
offer a number of toolbar buttons to help you navigate the Web. The exact names and
functions of these various buttons vary from browser to browser, but the most-used buttons
are usually always the same. Table 13.1 gives you a breakdown of the most common buttons.

These buttons, along with hyperlinks, will allow you to do a large majority of your Web
browsing. Both browsers, however, offer an additional set of buttons that let you
accomplish even more. Table 13.2 displays a few of these buttons.

Figure 13.3 shows the toolbars of both Netscape Navigator and Microsoft's Internet
Explorer. Both browsers enable you to adjust which buttons you actually display on your
screen. For more details on these two browsers, go to Lesson 14.
Figure 13.3.
Netscape Navigator and Microsoft's Internet
Explorer offer a wide variety of options to help you navigate and explore the Web.
History Does Repeat Itself
If you were to walk around a large library without
any clues as to where you were going, you would probably get lost before long.
Fortunately, many libraries have those colored lines on the floor to tell you where you're
going and where you've been.
This same type of tool comes in the form of the Go
menu in both Internet Explorer and Netscape Navigator. As you visit each page during a
particular session on the Web, your browser makes a note of where you've been in what is
sometimes called a history file.
You can access the history file through the Go menu
to go back instantly to any of the pages you've visited. Figure 13.4 shows a sports
addict's history file after a bit of cruising.
Figure 13.4.
The history file tells you everywhere you've been
during a particular session on the Web.
You need to know one more thing about how your
browser keeps track of where you've been. Obviously, the information about each page
you've been to has to be stored somewhere on your computer. This storage area is called
cache, which can be either a portion of your computer's RAM or hard drive where data is
temporarily stored for fast retrieval. Obviously, the more room available for cache, the
more links your browser can remember.
If you find that your history file never gets very
long, you can try to improve your situation by doing the following:
- Close as many open applications (besides your
browser) as you can. The memory that closing these applications frees up can often allow
your browser to keep a longer history file.
- Turn off the helpers. If you don't find yourself
using Java or some of the other built-in capabilities of your browser, disabling them may
free up more memory when you start your browser.
- Adjust your computer's virtual memory. Increasing
your virtual memory can improve performance for your browser.
CAUTION: In the Windows 95 Virtual Memory
control panel, you get this warning. These settings can adversely affect system
performance and should be adjusted by advanced users and system administrators only. Be
careful when adjusting these settings in Windows 95 or any other operating system, and
make note of the original settings so that you can restore them in case something goes
wrong.
Making a Permanent Record of Your Travels
I can think of one serious downside to the history
file. The second you quit your browser, your history is erased from the Go menu. As a
result, you start with an empty Go menu every time you start your browser.
Just A Minute: Internet Explorer does keep
the history file active between Web sessions. To view your history from past sessions,
however, you must choose Go|Open History Folder. Explorer also enables you to adjust how
far back you keep your history. Choose View|Options|Navigation and then adjust the History
setting to choose your taste.
Even if you didn't have to start over each time, you
would probably want a way to go instantly to an often-visited or favorite site without
having to find it every time. Most major browsers have this "guidemarking"
capability. Though different browsers call it by different names (as you'll learn in the
next lesson), I refer to these markers by the generic term "guidemarks" for now.
Adding guidemarks
Adding a guidemark in either Netscape or Explorer is
easy. Simply go to a site for which you want a permanent record and choose guidemarks|Add
guidemarks in Netscape or choose Favorites|Add To Favorites in Internet Explorer. That's
it.
From now on, by simply clicking the guidemarks or
Favorites menu, you see all the sites you can access with a click. When you first start to
surf the Internet with a browser, this process will be sufficient. As you become more
experienced, however, and need to keep track of more sites, you'll need to be able to do a
little more. Both browsers make modifying your guidemarks "drag-and-drop easy."
Editing guidemarks in Netscape
Soon you'll discover you've created a long list of
guidemarks that are so disorganized that you almost wish you didn't have them at all. In
Netscape, making your guidemarks more organized is easy.
After you make a few guidemarks yourself, choose
guidemarks|Go to guidemarks. A window like the one shown in Figure 13.5 then appears.
Changing the order of your guidemarks from this window is as simple as clicking a guidemark
and dragging it up or down. When you release your mouse button, the guidemark appears in
its new place.
Figure 13.5.
The guidemark editing window in Netscape is easy
to use.
You may want to complete other tasks with your
guidemarks, however, such as putting related guidemarks in the same folder or deleting
guidemarks. The following is a rundown of the most commonly used guidemark editing options.
(Figure 13.6 shows the guidemark editing window after some of these changes have been
made).
- Choosing File|Import imports guidemarks from another
browser for inclusion in your Netscape guidemark list.
- Choosing Item|Insert guidemark enables you to enter a
guidemark manually by name and URL.
- Choosing Item|Insert Folder enables you to create a
folder in your guidemark list. After you've created it, you can drag and drop related
guidemarks into the folder for easy organization.
- Choosing Edit|Delete removes a guidemark from your
list.
Figure 13.6.
All these guidemarks were edited within this
window.
Editing Favorites in Explorer
Editing favorites (guidemarks) in Internet Explorer
is also easy. Choosing Favorites|Organize Favorites takes you to a window that looks
almost identical to any other Windows 95 window, as you can see in Figure 13.7.
Figure 13.7.
Organizing favorites is similar to organizing any
other information in Windows 95.
Explorer is slightly more limited in how you can
organize and edit guidemarks. You can't simply move their order, for example, by dragging
and dropping. You can only move them from one folder to another. The basic functions are
still available, however:
- Folder Button: Clicking the Folder button at the top
of the window enables you to create a new folder into which you can move related
guidemarks.
- Delete Button: This button removes a selected
favorite from your list.
- Move Button: Clicking this button brings up a dialog
box that enables you to move your guidemark to any location.
No matter what browser you use, creating and
organizing guidemarks is simple with just a little practice. You will find that you can
organize literally hundreds of guidemarks to be available at your fingertips.
Summary
This lesson explained how the Web is similar to any
large library and how you need to apply some of the same rules when dealing with the
amount of information that's available. You also learned about many of the tools available
to help you organize the Internet.
You know that you can easily access toolbar buttons
to help you navigate and get specialized information. You also learned that Web browsers
keep an easily accessible history of where you've been. Finally, you learned how to keep
and organize a guidemark list of your favorite places on the Internet.
Workshop
The following workshop helps solidify the skills
that you learned in this lesson.
Q&A
Q I've seen the term "cookies" around
and don't know how they work. What are they?
A A cookie is a file that a server puts on
your machine when you access it. The next time you visit the server (or other
cookie-capable servers), this file can be read and additional information can be deposited
into it. Some people consider this use an invasion of privacy and don't accept cookies. To
have control over whether you choose to accept cookies, choose View|Options|Advanced and
then select the Warn Before Accepting "Cookies" option in Explorer, or choose
Options|Network Preferences|Protocols and then select the Accepting a Cookie option.
Q I am color blind and have a very difficult time
reading many of the Web pages that are out there. What can I do?
A Netscape Navigator gives you the option of
always displaying every Web page only as you want to see it. In Navigator, choose
Options|General Preferences|Colors. Choose a set of fonts and background colors that are
easy for you to read and then select the Always Use My Colors, Overriding Document option.

Activity
Your biggest task, both now and in the future, will
be to have a large and easily accessible list of guidemarks. Well, you might as well start
now. Spend an hour or so cruising the Net, making at least 10 guidemarks as you go. After
you're done, edit the guidemarks into at least two different categories. If you don't want
to keep them all, feel free to delete some of them after you've organized them.
