10.0 Introduction:

This course module covers web browsing and searching using IE7 and greater. Microsoft InternetExplorer (IE) has become the overwhelming standard for browsing web pages online with 55%

usage. All Windows-based computers come pre-installed with Internet Explorer, and versions

appear on other platforms. This prevalence (along with speed, stability, and ease of use) is whathas led to IE being the preferred web browser for both creators and users of the World Wide Web

(WWW). However, there are other good alternative browsers out there too that you can equally

use to surf the web, e.g., Apples Safari (~7%), Mozilla Firefox (~23%), Opera (~3%), Google

Chrome (~1%) and many more.

Note: before you fire that browser, do ensure that you a good antivirus and firewall solutions on

your computer to protect yourself from viruses. Also be warned that the web is like a Wild West the bad guys (hackers & cyber-criminals) lie in waiting like a lethal venomous green snake in

the grass and can hit any time while youre out & about there!

10.1 Definitions

These are some terms commonly used to reference objects on the internet or within Internet

Explorer.

URL: - Stands for Uniform Resource Locator. It is the address to a particular webpage.For example, the URL to Google search: http://www.ggogle.com

Homepage: - The homepage is the very first page that is displayed when InternetExplorer launches.

Address Bar: - The field that displays the URL of the current page. A user can type in adesired URL to display a specific page.

Shortcut: - A shortcut is a quick way to access a file or webpage. Usually a shortcut willappear as an icon on the desktop or in a menu.

Link: - A link is similar to a shortcut except links are objects within a webpage. This is

an example link to this page.

Clipboard: - The clipboard is a temporary storage place for content. A user can copy tothe clipboard within one program and paste from the clipboard in another program.

Cookies: Cookies are bits of information a website may store on a user's computer.Typical information that is stored include, items in a shopping cart, what links a user has

followed, and other information the website may need in order to customize their site to a

particular user.

Fig. 10.2: Web page layout.

Figure 10.2 shows the screenshot of the Microsoft Internet Explorer browser window the main

part of the window is taken up by the web page. If you wish to learn how to navigate around aweb page please visit the Navigation section of this lesson.

The web browser has various tools located above the displayed web page, these are known asToolbars, there are additional tools available on the left hand side of the browser called the

Explorer bar, and at the bottom of the web page is the status bar.

We will start by looking at the Toolbars, as you will see when looking at the toolbars there

operation is inter-linked with the Explorer bar.

10.2 Basic Layout of Program the Menu bar:

The Menu bar is normally located at the very top of the web browser, as you can see it has

various sections - File, Edit, View, Favorites, Tools and Help, see Fig. 10.3. When you

left click on each of these menu sections a drop down menu appears enabling you to do various


6/41




6

actions as follows. (Note that not all functions are mentioned some functions are not normallyrequired when navigating the World Wide Web - however the major functions are all discussed.)

Fig. 10.3: Menu bar.

File - The file menu deals with the current open document, from here you can open a newdocument such as another web page, save the web page, alter the page setup, print the web

page, send the web page by email and find out the properties of the web page.

Edit - The edit page enables you to copy details from a web page to your clipboard (Theclipboard saves the details so you can paste the copied material into another document). The

edit section also allows you to find (on this page) - this allows you to look for a certain wordon a web page.

View - The view section enables you to change some browser settings; you can select whattoolbars you wish to display. For example you can decide not to show the radio toolbar if you

dont use it. From this section you can also amend the text size of the web page.

Favorites - From here you can create a list of favorite web sites, the chances are that yourInternet Service Provider has already given you a starting list of web sites. If you wish to addmore to your favorites you can do it simply in this section.

Tools - The tools section provides some other useful tools, one of the most important sectionshere is the Internet Options - from this area you can control your security settings.

Help - The help sections gives you various help functions and version details.

10.2.1 The File Menu

10.2.4 View Menu

Fig. 10.6: The View menu

The view menu has a number of functions tailored to the look of Internet Explorer.

Toolbars: - A submenu with options for showing different toolbars. Experiment with thedifferent choices to see what each option does. Placing a check next to each option

enables them and makes them visible. Those options that are not checked are not enabled

and not visible. Just remember to re-check the options that were originally checked.

Status Bar: - The status bar is at the bottom of the window. It displays information aboutvarious aspects of Internet Explorer. For example, when a user clicks on a link, the

number of images left to download is displayed along with what page is loading.

Explorer Bar: - A submenu with various explorer options. Search opens a search box tosearch the internet. Favorites opens a window of all the user's saved favorites. History

opens a list of all the websites a user has visited in the last few weeks.

Go to: - A submenu for jumping to a previously viewed page. Identical functions to theback and forward buttons in the navigation bar.

Stop: - Stops the current page from loading. Identical to the stop button in the navigationbar.

Refresh: - Reloads the current page. Identical to the refresh button on the navigation bar.

Text Size: - Makes the size of the text on a current page larger or smaller. Experimentwith the different options to see their effects.

Encoding: - Allows the user to pick a language that may be displayed on the page.Usually the best option is auto select.

Source: - Shows the source HTML code for the current page.

Full Screen: - Puts Internet Explorer into kiosk mode. Try it now to see what it lookslike. Remember to press "F11" on your keyboard to return to normal mode. Sometimes

users accidentally hit the "F11" key just above the backspace button and are unable to get

Internet Explorer back to normal.

10.2.5 The Favorites Menu

Fig. 10.7: The Favorite menu

The favorites menu provides a means of saving websites that a user finds useful or interesting.

When the user wants to re-visit that site at a later date, they can simply click on the saved favoriteand it will go directly to the corresponding page.

Add To Favorites: - Opens up a box asking where to save a favorite for the currentlydisplayed page. The user may opt to categorize their favorites into subfolders.

Organize Favorites: - A box for moving favorites to various sub folders within thefavorites menu.

10.2.6 The Tools Menu

Within the tools menu is an option called Internet Options.

The Internet Options window is split up into 7 tabs.

General Tab: - Has options to set the user's homepage, clear out temp files, and clear thehistory cache.

Security Tab: - Has many different security settings. Settings set too low may leave auser vulnerable to attack by hackers, settings too high may render some sites non-

functional. As a rule of thumb, the default of medium is a safe place to leave this setting.

Privacy Tab: - Has a slider setting for the handling of cookies. Cookies are generallyharmless and a setting of medium is a good rule of thumb for the security tab.

Content Tab: - Contains settings for content filtering. Some organizations, like schools,will have additional filtering software to filter out inappropriate materials. Auto complete


10/41




10

is another option on the content tab. Auto complete is designed to save information typedin text fields like login information so that a user does not have to type it in every time.

To turn this feature on or off, check or uncheck the boxes for the different types of text

fields.

Connections: - Stores information pertaining to how a computer connects to the internet.

Programs: - Stores which programs Internet Explorer will use for each internet service.

Advanced: Has settings pertaining to various aspects of the web. A good rule of thumbhere is the default settings.

Fig. 10.8: The Tools menu

10.1.1 The Toolbars:

- The "Standard Buttons" toolbar is the primary way to navigate back and forth betweenpages, as well as refreshing and stopping the loading of pages. It has the familiar Back,

Forward, Refresh, Home buttons.

- The "Address Bar" is the primary entry for URLs (uniform resource locators) to browse topages

- The "Links" bar contains preset links to websites, and can be altered for one-click access toyour favorite sites.

Simply type in the address hit the ENTER key or click the icon to launch the website or to

cancel, see Fig. 10.12.

Fig. 10.12: The Address bar

10.3 Activating a Link

A hypertext linkon the Web, like a link in a chain, connects two points. Links can appear in two

ways: as text that you click or as a graphic that you click. A text link is a word or phrase thatusually appears in a different color or underlined, e.g., a link to Google Home page. A graphic

link is a graphic image that you click to jump to another location, e.g., click the home icon to

jump to Google home page . When you aren't sure whether text or a graphic image is a link,point to it with the mouse pointer. When you move the mouse pointer over a text or graphic link,

it changes shape from to . The pointer indicates that when you click, you will activatethat link and jump to the new location. The destination of the link appears in the status bar, and

for some graphic links a small identification box appears next to your pointer.

As shown above, the text links are usually underlined and colored. Each link gives Internet

Explorer the information needed to locate the page. When you activate a link, you jump to a new

location, called the target of the link. The target can be either another location on the active

Web page (for example, the bottom of a Web page often contains a link that targets the top), adifferent document or file on your computer, or a Web page stored on a remote Web server

anywhere in the world. The amount of time necessary to link to the target, called the responsetime, varies, depending upon the number of people trying to connect to the same site, the number

of people on the Internet at that time, speed of your internet connection and the site design.

Activating a link starts a multi-step process. Although Internet Explorer does the work for you,

following the sequence of events is important: it helps you recognize problems when they occur

and understand how to resolve them.

Figure 10.13 illustrates the string of events that occur when you link to a site, e.g., click thefollowing link to: Global Open Versity home page. When you point to a link, the status bar

displays the address of the link's target. When you click a link, the activity indicatoranimates, and the status bar displays a series of messages and progress bar indicating that Internet

Explorer is connecting to the file targeted by the link, is transferring data, and finally, is fully

done.

Fig. 10.13: Sequence of web page loading

From Figure 10.13, you can observe how the Web page is build as Internet Explorer transfers

information to your screen in multiple passes as can visualized in the Status progress bar display.

The first wave brings a few pieces to the page; with each subsequent pass, Internet Explorer fillsin more details until the Web page is complete. The progress bar fills in to indicate how much ofthe Web page has transferred. The vertical scroll box scrolls up as Internet Explorer adds more

information and detail to the page. Although you don't need to wait until the page is complete

before scrolling or clicking another link, it might be difficult to determine links and other

information until the page is mostly filled in.

10.3.1 Setting your home page:

To set your home page, do the following:

1. Select Tools > Internet Options, Fig. 10.14(a).

Fig. 10.14: Setting your Home page in IE

2. From the Internet Options dialog box Fig. 10.14(b), clickUse current button, and then clickOK to exit.

3. To go to your Home-page after a web surfing session, just click the Home icon .

10.3.2 How to Initiate a Link to a Web Page: (www.globalopenversity.org)

1. Point to the About Global Open Versity link. Notice that the pointer changes shape fromto indicating that you are pointing to a hypertext link. The status bar shows the target for

that link, as shown in Fig. 10.15.

Fig. 10.15: Initiating a web link


15/41




15

2. Click to activate the link. The status bar notes the progress of the link, although this might

happen so fast that you can't see it. When the status bar displays, "Done," the link is

complete and the Web page that is the target of the link appears.

If a message dialog box opens, the link was not successful. Click the OK button to close the dialogbox, and repeat Steps 1 and 2. After you click the hypertext link, be sure not to click anywhere

else on the page until Internet Explorer completes the link.

Note: You connected to a Web page with a single click. Using hypertext links is a simple way tomove from one Web page to another. Internet Explorer displays text links you've already visited,

or activated, in a different color so you know which links you've already tried.

10.3.3 Exiting Internet Explorer

To exit an Internet Explorer we page, do the following:

Click the Close button to close Internet Explorer.

When connecting from home, if you are prompted to choose whether or not to stay connected to

the Internet, click the Stay Connected button because if you dont click that you will be

disconnected from the internet and you need to redial in again to be connected.

10.4 Connecting to a Web Site with a URL

Clicking a hypertext link is just one way of connecting to a Web page. Clicking links, often

called "surfing," or Web browsing is an easy way to navigate the Web when you don't have

a specific destination in mind and just want to follow links. To connect to a particular site,

however, you need to know its address, called its Uniform Resource Locator or URL. A URL

is composed of a protocol identifier, a server address, and a file pathname. If the file is stored in a

folder, the folder name appears as part of the file pathname, as shown in Fig. 10.16, for an

example.

Fig. 10.16: Connecting to a web site

Web servers that serve Web pages, as shown in Fig. 10.16, use standardized procedures, called

protocols, to transmit files. Web documents travel between sites using HyperText Transfer

Protocol or HTTP, so the URL (address) for a Web page usually begins with "http://" to


16/41




16

identify its type. Another common protocol you might see is File Transfer Protocol, or FTP,

a protocol that facilitates transferring files over the Internet.

The server address contains the domain name and tells the exact location of the Internet serverand the type of organization that owns and operates it. For example, in the domain name

"www.greenafrica.org" the "www" indicates that the server is on the World Wide Web, "org"indicates the name of the organization that owns the server (Assumption greenafrica), and "org"indicates that it's an Not-for-profit site. The entire domain name tells you that

GREENAFRICAAFRICA is a non-governmental organization site on the Web. Outside the

United States, domain name types sometimes include a two-letter country code. For example,

".ke" identifies a server located in Kenya. Table 10.2 lists some common domain name types.

Table 10.2: Domain name Types

Domain Description Domain Description

.com Commercial sites .uk United Kingdom

.org Nonprofit organizations .ke Kenya

.net Networking organizations .fr France

.edu Educational organizations .ca Canada

.gov Government agencies .jp Japan

.mil US Military agencies .au Australia

The filename extension for Web pages is usually ".html" (or just ".htm"), which stands for

hypertext markup language. The greeafrica file for the Partnerships program, for example, is

named "Partnerhsip_main.htm" and is located in the Partnerships folder on the www server.

Remembering two important facts about a URL makes using a URL to access an Internet site

significantly easier:

Some servers are case-sensitive, and they might interpret the URLhttp://www.mydomain.com differently from http://www.Mydomain.com. If the server

cannot interpret case-sensitive addresses, it cannot locate a URL whose characters' cases

have been incorrectly entered. Whether you copy a URL from a magazine article orreceive it from a friend, do ensure to copy and type the characters and their cases exactly

in the Address bar.

Internet sites continuously undergo name and address changes. A network server mighthave changed names, the previously visited webpage link might be stored in a different

folder, or the page you want may no longer be available. Remember no one person ororganization controls the Internet. Organizations and individuals can add, rename, and

delete folders and files at will. Often when a URL changes, you can find the forwarding

address (URL) at the old URL. Other sites will simply vanish from servers, leaving noforwarding information.

For example, clicking the link shown in Fig. 10.17 leads to a page not found indicating

a broken link, page moved or deleted and is usually displayed with "HTTP Not Found"

page display, as shown in Fig. 10.18.


17/41




17

Fig. 10.17: Initiating a web link

Fig. 10.18: Broken link page

Before you actually enter a URL in the Address bar, you should be aware of the Internet Explorer

AutoComplete feature, which remembers Web addresses and other information that youpreviously entered. When you type a URL you've entered before, Internet Explorer attempts to

complete it for you. As you type, a list of suggested matches appears. If no suggestions match the

address you want to enter, for now simply ignore the suggestion list and continue typing the

URL.

Internet Explorer also attempts to complete URLs that you only partially type. For example, if

you type the incomplete URL "www.nasa.gov" Internet Explorer connects you to

http://www.nasa.gov/missions/index.html , the NASA- Missions page at the NASA Web

site.

Remember to access an Web site, ensure to enter the correct URL, i.e.,

Type a URL into the Address box, and click the Go icon .

or

Type a URL into the Address box, and press Enter key on your keyboard.

10.4.1 How to Connect to a Web Page using a URL:

1. Launch Internet Explorer and be sure the Standard and Address toolbars are visible and thebuttons display icons with text labels.

2. Click the Address box to highlight the current entry, which should be the URL for your homepage.

3. Type http://www.nasa.gov/missions/index.html in the Address box. Do ensure to typethe URL exactly. Notice that two forward slashes always follow the http protocol identifier.

4. Click the Go icon. Internet Explorer connects you to the Web page at the address you typed.The status bar tracks the progress of the connection and informs you when the page finishesloading.

5. Locate any link on the page and click it to access the target page or site. Now use all yourprevious negation you learned earlier to browse the website to find out what the site is allabout.

10.4.2 Aborting a Connection to a Website

When you enter a URL or click a link that targets a Web page, three outcomes are possible:

1. You successfully reach your target page. Internet Explorer contacts the server, locates thefile, transfers it from the server to your computer, and displays it on your screen.

2. The server is busy and perhaps overwhelmed with too many requests. You get a serverbusy display alert page. You'll need to try again later.

3. The URL targets a file that doesn't exist or has been moved. Documents that becomeobsolete are often removed from Web servers or moved to new locations. You get a

"HTTP Not Found" display on your screen. There are many reasons for this type of cases:

The links that point to those documents are not always updated. Web hosts are also

sometimes taken out of service. Some inactive sites supply an informational page that

tells you the site is no longer active; others let you know that the URL has changed andprovide the new URL; still others supply no forwarding information.

Like an expressway, the Internet sometimes becomes so congested that the paths cannot support

the number of users at peak times. When this happens, traffic backs up and slows to a halt, in

effect closing the road. In such cases, aborting, or interrupting, a connection is like taking

the next exit ramp on the Internet. When the response time seems too slow (longer than a few

minutes) or nothing seems to be happening, you have no way of knowing how long connectionwill take. You can tell that a link is stalled when the activity indicator is animated, but the status

bar makes no progress. Rather than wait for a site that has a long queue or is so busy it cannot

respond to your request, you can abort the connection.


19/41

10.4.2.1 How to Abort a Connection

To abort the connection, do the following:

Enter the URL or click the link whose target you want to open.

If the target does not open and the status bar shows no progress, click the Stop button .

10.4.3 Attempt to Connect to a Defunct (Obsolete) Site

If Internet Explorer cannot find the necessary Domain Name System information to locate the

server indicated by the URL, it terminates the connection and informs you that it cannot find the

page with a "HTTP Not Found" display on your screen.

10.4.4 Attempt to Connect to a Nonexistent Site

1. Enter the address www.collins.rockwell.com. This is the old Rockwell Collins web

address. You should see details regarding the location of a new address,www.rockwellcollins.com, a shown in Fig. 10.19. This is an example of a site which no

longer uses a particular address and has left provision for letting others know of the new

address.

Fig. 10.19: Redirected website from old site to a new one.


20/41




20

2. In the next example, enter the address http://www.greenafrica.com/. You should see anerror message stating that - The webpage "www.greenafrica.com" cannot be found.

This is an example of a nonexistent web site, see Fig. 10.20.

Fig. 10.20: You reached a no-existed website

10.5 Browsing the Web Pages

In Internet Explorer, you can flip through Web pages you've visited in a session as though they

were pages in a magazine this is also known Web browsing or surfing. Rather than

memorizing and retyping URLs of sites you have visited, you can use toolbar buttons to move

back one page at a time through the pages, move forward again one page at a time, or return to

the "front cover" of your home page. Internet Explorer "remembers" which pages you've

visited during your current Web session and provides navigation buttons on the Standard toolbar

so that you can easily move through those pages, see Table 10.3.

Table 10.3: Web browsing navigation tools

Button Icon Description

Back

Returns you to the Web page you were most recently viewing. If you clickBack arrow twice, you return to the page you were viewing before that, andso on, until you reach the first page you viewed in the current session. Thisbutton is active only when you have viewed more than one Web page in thecurrent session.

ForwardReverses the effect of the Back button, sending you forward to the pagefrom which you just clicked the Back button. This button is active only afteryou use the Back button.

10.5.1 Downloading & Saving Files:

One of the first things to understand while browsing the

web is that each page you go to is, in actuality, just a filelike any image, song, or program you have on your

computer. It can be viewed, edited, and downloaded off

the web to your own computer. All HTML files, images,

etc. online can be downloaded. To download a file, click

the right mouse button over the link (again, be it animage, HTML file / web page, etc.), and click "Save

Target As", as shown in Fig. 10.22. A Save Webpagedialog box should pop up prompting you to save the file

to a desired location.

10.5.2 Editing a Webpage:

Rather than downloading and saving a webpage with theabove method, there are two other ways to get right into

editing the current page in your browser. The first is to

simply select File > Edit with MSWord, see Fig.

10.23. This will open the page in MSWord for editing ina WYSIWYG (What You See Is What You Get) style.

You can also use MS FrontPage, MS Publisher, AdobeDreammeaver and many others Web Editors that you can

download and use for free.

10.5.3 Finding text on a page:

It is possible that you will come across long pages of text. To

search for a key word or phrase you are interested in, select Edit

> Find (or Ctrl+F) and enter in what you wish to search for as

shown in Fig. 10.24. The first instance of the text will behighlighted on the page. You can continue searching for more

instances on the same page.

10.6 Printing a Web Page

Although reducing paper consumption is an advantage of browsing for information online,

sometimes you'll find it useful to print a Web page. To print a Web page, clickFile > Print

(a) to access the Print dialog box (), as shown in Fig. 10.25.

Web pages can be any size; however, printers tend to use 8 1/2" X 11" or A4 paper. When you

print, Internet Explorer automatically reformats the Web page text to fit the page dimensions.

Because lines may break at different places or text size may change, the printed Web page may

be longer than you expect. You can specify the number of pages you want to print in the Print

dialog box, Fig. 10.25b.

You can also specify header text to appear at the top of the printed page or footer text to appear atthe bottom. The header and footer can contain information such as the URL, the date, the current

page number, the total pages number, and any text you want to add. You enter header and footer

text in the Page Setup dialog box. You indicate the text you want to include by typing codes like

those shown in Table 10.3.

Table 10.3: Header and Footer Codes

Code Description

&w Window title

&u URL

&d Date

&t Time

&p Current page number

&P Total number of pages

&b Centers text immediately following these characters

&b&bCenters text immediately following the first three characters, and right-justifies

text following the second &b.

Note: The Print dialog box also gives you the option to print all linked documents and a table of

links, which lists all links in the document.

6. Click the Print button to print the Web page.

You can also print a page quickly by clicking the Print button on the toolbar. However, the

Print button bypasses the Print dialog box and prints using default settings, so use the Print

button only when you don't need to limit the number of pages, choose a different printer, or

change any other print settings.

10.7 Getting Online Help

Internet Explorer's Help system is an online reference. You can open the Help window from the

Help menu or click the Help buttons found in certain dialog boxes. The Help system provides

Table of Contents, Index, and Search tabs. Similar to a book's, Internet Explorer's Table of

Contents tab lists the main topics and subtopics in the Help system, grouped by topic. The Index

tab, like a book's index, lists Help topics alphabetically. You can type a topic in the Index box to jump to indexed topics on that entry. Finally, the Search tab lets you type a keyword and then

locates all topics containing that keyword.

After you find the Help topic you want, it "floats" on top of the screen so you can refer to the

suggested steps as you work. You can click the Hide button on the Help toolbar to reduce theHelp window's size.

10.9 Using the Back and Forward Lists to Browse the Web

Recall that the Back and Forward buttons each contain arrows that you can click to open Back and

Forward lists, which show all pages going back to a certain point in time and all pages goingforward to a certain point in time. This option lets you return randomly to pages you viewed

earlier in the session with a single click. Although you can click the Back button repeatedly toreturn to a page, the Back or Forward list is usually quicker if you've navigated multiple Webpages. If you haven't yet navigated any pages in the current session, however, the Back and

Forward buttons are gray, indicating they are unavailable.

10.9.1 How to use the Back and Forward Lists:

1. Click the Recent Pages drop-down menu arrow con immediately to the right of theForward button. The Recent Pages visited are listed, as shown in Figs. 10.35. Your Recent

10.10 Using the History Explorer Bar

The Back and Forward lists only recall the sites you most recently visited in the current session(the number of sites on the menu depends on your browser's settings). To view information on all

recently visited links, including those you visited in previous sessions, you can view the History

Explorer bar. Explorer bars appear on the left of your screen and contain lists of links that helpyou find the pages you want. Internet Explorer offers four Explorer bars: Search, Favorites, and

History, all accessible from the View menu. The History Explorer bar provides a list of the

servers you've visited each day for the number of days specified in your browser's settings.

10.11 Organizing Favorite Pages in Folders

While surfing or browsing the Web, you might find an interesting or unusual site to which youwant to return. Rather than trying to remember the site's URL, you can add it to your list of

favorite pages usingAdd Favorites

icon . You can access the pages in yourFavorites

folderfrom the Favorites menu on the Start menu or from within Internet Explorer, via the Favorites

button or menu.

10.11.1 Adding a Page to the Favorites Folder

Adding a page to the Favorites folder is helpful when you want to return to a specific Web site,

try other links on that page, or show someone a certain site. You can add any Web page to yourFavorites folder by using the Add to Favorites option.

How to Add a Page to the Favorites Folder:

Fig. 10.42

10.12 Managing Favorites Folders

Most browser users organize their favorite pages into folders grouped by category so finding a

certain page is easier. The Favorites collection included with Internet Explorer comes withseveral folders that contain a variety of interesting links, but you can add your own folders. This

window lists folders, indicated by and favorite Web pages, indicated by their custom icon or theStandard toolbar, depending on how Internet Explorer was installed on your computer.


35/41

3. Press Close when done.

10.13 Dangers of Navigating Linked Pages

Recall that web pages will generally contain "links," which when clicked, bring you either to a

different portion of the site, a file to view, or to a different site all together. A link can be eithertext or an image; links will generally be noted by blue text or an underline, or will change colors

if the cursor is placed over it. By simply placing your cursor over a link (without yet clicking it),

you will notice in the bottom left-hand corner of IE, the address of the file linked to will appear


36/41




36

as text (for example, on the Green Africa Network home page, by placing the cursor over thewords "Projects" in the "Site Info" section, you will see the link pointing to

"http://www.greenafrica.org./Projects/Projects_main.htm "). By clicking that link, the browser

will then open the file you have clicked.

Links that go to files with extensions such as .htm, .html, .shtml, .jhtml, .php, .asp and theirvariants will bring you to another web page. Notice what the file extension of a link is before youclick it; any files can be linked to online.

Viruses Warning!

Note: While the vast majority of links will be other web pages (and images), you may come

across files such as .zip, and .exe. Hence, be aware of what it is, exactly, that you are clicking;

you might unintentionally click a link containing viruses which could harm your computer. Formore information, search the web on information relating with viruses, and how to defend against

them.

10.14 The Web Cache:

While viewing web pages, Internet Explorer will save files to a "Temporary Internet Files" folder

on your computer. This helps speed up the loading of pages that you visit on a regular basis.

However, this may also cause you to miss regular updates on a web page. If refreshing the pagedoes not work, you may wish to clear the cache of these temporary internet files.

To clear your browser cache, do the following:

In the Tools > Internet Options window, under the section for "Temporary Internet files",you can delete these files and start with a fresh load, see Fig. 10.46.

Fig. 10.46: Deleting cache from the Temporary Internet files.

10.14 Searching the Web- The Search Engine

To successfully search the web you need a good Search Engine. Some of the best search enginesare: Google Search, Yahoo Search, MS Bing Search and etc. There are other more specialized

web search tools like Craigslist, which great for classified ads search for jobs, apartments,volunteer, sell/buy, and just about anything over the sun. So the next question you may is: What's

the best search engine? The one you learn to use well.

Search engines can help you find information on the World Wide Web, but you'll get more chaff

than wheat unless you learn general search strategies and the particular search syntax for your

favorite search engine. In this tutorial well stick with Google Search Engine, which you canaccess by typing: www.google.com in your browser Address bar, as shown in Fig. 10.47

Fig. 10.47: Google Search Engine

So the next question you may ask is; how can I maximize my search results:

Many people think that the value of a search engine is this: Put in a little information andyou get a lot in return.

But the best searching is based on this principle: Put in a lot, and you might just get backwhat you want.

To learn the lingo for your favorite search tool, look for "Help" or "search tips" on itsmain page.

10.14.1 Performing a Simple Web Search

Now lets start by performing a simple web search, so go ahead and type UFO in the Toolbar

search and click the search icon , as shown in Fig. 10.48. As you can observer, we have both
http://www.google.com/http://www.google.com/


38/41




38

images/pictures and text links for information on UFOs. Now browse the listed sites and enjoyinglearning about UFOs.

Fig. 10.48: Google Search Engine: Search UFO keyword.

10.14.2 Tips for Searching the Web

1. Be Natural

Type in what you want to know, rather than a list of synonyms. Websites are written in

flowing language, and search engines are being taught to understand the same.

If you would've asked a fellow human "is jogging and walking healthy?"

Then query the search engine "jogging and walking" AND health rather thanjogging walking healthy


39/41




39

2. Use Rare Words

The more unusual or uncommon the keywords you use are, the more specific the results will

be. Taking a moment to think of a valid yet uncommon word is a valuable technique. You

may also use enclose your keyword(s) with " " to be more specific.

UFO turned 37,500,00 hits Apartheidfetched 47,700

Kefa Rabah fetched 2,754

And it narrows down to 1,520 hits when you enter Kefa Rabah with quotes.

It even gets better when you enter Rabah Kefa which returns only 166 hits

Note: For a few engines the word order is important, so always enter the rare word first. Andinterchanging the order of keywords could lead to better or worse results!

3. Exclude Words

This can be achieved by using a "-"to filter out unnecessary hits.

Assume that you intend to visit London this summer. You also know that theres a great Sharon Stonehairdressing salon downtown. So you decide to search the homepage of Sharon Stone.

Keyword: Sharon Stone gives 14,400,000 hits; Sharon Stone Hairdressing (914,000);Sharon Stone Hairdressing London (351,000)

Now lets try be more specific to avoid all the millions of unnecessary pages dedicated to the American actressfilm star, use this:

"Sharon Stone" hairdresser AND London -"Sharon Stone Actress" -movies -superstar pictureswill result in a manageable 1,220 hits

Note: You can add or remove phrases to improve your search experience.

4. Spell It Right

Incorrect spelling can lead to tremendous loss of information and a waste of your precious

time. Assume you intend to head to the tropical equatorial heat of the coastal city of

Mombasa Kenya. So lets search Mombassa instead

Mombassa 266,900 hitsMombasa 3,350,000 (Correct spelling) hits

Note: Its also important that you be aware of the difference between UK and American

English spelling, e.g., Program and Programme. This is very important when doing a job

search. In this case: Program Manager (American) and Programme Manager (UK) are but

the same thing. The only exception is in computer application where the spelling is the same.

In some cases, Google will prompt you for the correct spelling.


40/41




40

5. Recognize Stop Words

Avoid using common words in your keyword(s) search. Several hundreds of extremelycommon words are deemed to be "stop words". They vary from search engine to engine, but

always contain words like: the, of, who, where, about etc. Therefore, in most cases Search

Engines filters these words in order to save disk space or to speed up search results. It doesn'tmatter whether they are embedded in a phrase or if they have a + before them, they will not

be included in the search. However, you can still use them, but it is smart to be aware of the

process.

Note: Googlewill find complete phrases, including stop words, when the phrase is "within

quotes". However, a phrase without quotes will ignore the stop words

For example, "surf the web" contains two stop words: the & web.

- Consequently the search engine will only look for "surfing".

- If you are aware of this, you can add a more specific keyword to narrow your search, like: "surfing lessons"

Note: Googlewill let you know of any words it has excluded

6. Reverse Questions

In most cases, search engines will look for pieces of text that match your query. Web pagesare more likely to contain answers than questions - so search for the answer. Therefore, it is

important that you phrase your query how you would expect the answer to read - the

difference appears slight, but it makes a huge difference.

"Why do volcanoes erupt?"instead of "Volcanoes erupt because" "UNEP stands for" rather than "What does UNEP stand for?"

"When did WWII end?" rather than"WWII ended in"

7. Dead Link Solutions

Locate that hidden file on the web. Try shortening the URL to the next subheading to see if

you can access that elusive folder containing wanted file. Keep doing so until you get to the

point that works. Then browse from there to see if you can track down the file that you want.

If http://www.mycompany.com/research/rd/superproduct.html returns an error,

try http://www.mycompany.com/research/rd/

and if you still get an error, try http://www.mycompany.com/research/

keep trying until reach the root domain http://www.mycompany.com/

Note:Googlehas most of the web cached. If a link is dead, clicking on the Cached link will

bring up how it looked when it was indexed

You can also get help from: The Wayback Machine to find historical copies of web pages.

41/41


8. Not So Useful Huge Pages

At times while surfing the web, you might come across web-pages that appear at the top of

your search result, but may or may yield that useful information you so desired. In some

instances, the reason a page appears in the results is because it is one very long page of text,briefly mentioning hundreds of subjects or most searched keywords. Sometimes these are

useful, for example, in genealogical searches. Often they are not...

In general, the most useful pages will be between 10k and 80k

To locate the text or phrase within a huge page, with IE browser click from menu "Edit >

Find on this page..." then enter the phrase to find.

Note: Google results list a maximum size of 101k. Many of such huge pages will be much,

much larger and take forever to download.

9. Boolean Algebra

Named after an Irishman tradesman George Boole; a man with great gifted studious characterand active mind. Boolean phrases (algebra) are a system of logical combinations, using wordslike AND, OR & NOT. When used, it is best to always capitalize them.

Boolean Description

AND or "+"

OrangeANDMangoesANDQuaver

Orange+Mangoes+Quaver

AND requires the word to be present

OR

ColaORTea

OR allows either word to be present

NOT or "-"

ColaNOTJuice

Cola Juice

NOT excludes words. In this example results should display sites about

communism and not comedy.
