Internet: Practical 1
Get to know your way around your web browser
A web browser is a piece of software that
allows you to access Web sites and
navigate between them. All Web browsers
are the same in principle. The basic toolbar
buttons for web navigation are the same in
IE5 as in older version of IE, and
analogous to those in Netscape. Web
browser contains an address box, in which
you type a Web address (known as ‘URL’
or Uniform Resource Locator), and an area
in which Web pages are displayed.
The Address Box
This is where you type Web address (Try! type yahoo.com in the address box) and click on Go or press
the Return or Enter keys) to download the Web page.
Back and Forward buttons
Use the Back and Forward buttons to navigate through downloaded pages
Refresh
If a Web page is taking a long time to down load then click on Refresh button. Refreshing a web page
will seek a new copy of that page, and might load it faster as it will use a physically different Internet
route to send back the page.
Home
Use the Home button to return to your browser’s home page. This is the web page which is first
displayed when starting your web browser and can be configured to any web page you prefer.
Links
This will allow you to set up automatic links to your favourite Web sites via a button toolbar.
Task1 Understanding Web browsers
Objectives
1. Access web sites and navigate them using IE5.
2. Find out how you could easily access web sites that are visited frequently.
Method

Task 1.2: Place your cursor in the address box, and type in the address ( as in the figure below):
www.bbc.co.uk
Note that the prefix ‘http://’ will be automatically inserted. Then press<Enter>.

cursor.

Task 1.3: Add the above Web address to Link menu
(frequent visits)
To add the BBC link to the list, drag the icon located
in front of the web site address(in the address box) and
drop it on the links button.
Task 1.4: On the left side of the BBC home page, click
on the hyperlink News
A new web page will be displayed with the latest news
topics as in the right figure.
Task 1.5: To return to the home page of your browser, click on the button Home in the toolbar near the
top of the window.
Move backwards and forwards through the web pages you have just visited by using the Back and
Forward Buttons next to the Home button.
Note Next time you enter the address of the BBC web site in the Address box, a drop-down list with
possible matches of the web sites will appear. Rather than typing out the test of the web address, you
can use the arrow keys to select the right address in the menu list and press Enter.
Searching the Web
Quickest way to find information is by is by using a search engine. Which search engine ?
The Web site at www.searchenginewatch.com explains how the main search engines work and how
efficient they are. Here are the addresses of some popular search engines:
www.altavissta.com
www.excite.co.uk
www.hotpot.com
www.lycos.co.uk
www.northernlight.com www.yahoo.com
www.google.com
http://www.metacrawler.com/
Be as specific as you can in your search and tell the search engine exactly what you are looking for.
You can get tips on better searching from the engines themselves.
Searching using Internet Explorer
IE5 has in built search features that can be used as an alternative to using a search engine.
The Search Bar
The search toolbar button is used to launch Internet Explorer’s Search Assistant.
This can be also used for searching newsgroup messages and maps.
Try: select the appropriate search category, enter a keyword and click the Search button.
It is also possible to re-run previous searches, by selecting Previous searches and clicking on a
previously saved keyword entry.
Auto-Search
Search keyword can be typed directly in the Address box to invoke a search.
Related Links

you like, you can select this option to get a list of web sites similar in content to the current one.

How to refine searches with AltaVista
Search engines have rules to help you refine a search. Always use these, particularly if you search on
popular subjects, as general searches reveal hundreds of Web sites.
1.
Type’+’ before a word that must be on a Web site, ‘-‘ before one that must not.
Examples: Electronic+medical –electronic
2.
Use speechmarks when you’re searching for precise phrases, like film titles, Example: “The
Full Monty”.
3.
Use image:filename to search for pictures. Example: image:Ultra sound will find pictures
containing ‘ultra sound’ in the title.
4.
Use an asterisk ,*, to broaden a search. Example: night* will find nightmare and nightingale.
